Slkor SL8402 – Reliable Alternative to DIODES ZXMS6005DGQ & Onsemi NCV8402 Smart Power Switches




Category: Smart Power Switches | Package: SOT-223 | Voltage: 42V | Input Voltage: 7V | RDS(ON): 0.28Ω | IIN: 20mA

High-Performance Replacement Solution

Slkor provides the SL8402, a high-reliability Smart Low-Side Power Switch designed as a direct alternative to DIODES ZXMS6005DGQ and Onsemi NCV8402.
With comparable electrical characteristics and built-in protection features, the SL8402 ensures excellent compatibility, stable performance, and cost-effective supply for both new designs and replacement needs.

Key Features & Protections

  • Low Input Current Consumption

  • Short-Circuit Protection & Voltage Clamping

  • Integrated Current Limiting Function

  • Thermal Shutdown & Auto-Recovery

  • Overvoltage Protection during Inductive Switching

  • Built-in ESD Protection for Input Pin

  • RoHS Compliant, Standard Power MOSFET

The SL8402 operates across a DC–10 kHz frequency range and can reliably drive resistive, inductive, or capacitive loads. It is particularly suitable for automotive relay driving, industrial load control, and applications requiring high reliability and protection.

How It Works

When excessive load or poor thermal dissipation causes overheating, the SL8402’s thermal shutdown circuit activates automatically to protect the device.
Once the temperature drops below the hysteresis threshold, the switch resumes operation automatically, ensuring long-term stability.
Meanwhile, its overvoltage clamping circuit safeguards the MOSFET even when the IN pin is at 0 V, ensuring full-time protection for inductive or switching loads.

Applications

  • Vehicle-specific relay drivers

  • Industrial automation systems

  • Smart power modules

  • LED lighting controls

  • Inductive or capacitive load driving

【SLKOR semiconductor】Protecting Automotive Electronics: SLKOR's SLESD5311N-2TR TVS Diode in Focus

图片
 Introduction   With the rapid advancement of technology, automobiles are making significant strides toward intelligence and connectivity. Modern in-car systems integrate numerous electronic devices such as entertainment systems, navigation systems, and autonomous driving sensors, all of which demand high voltage stability. However, during vehicle operation, various transient overvoltage threats may occur, such as those caused by engine ignition, lightning induction, and power switching. These overvoltage pulses can severely damage onboard electronics, causing system failures and negatively affecting driving safety and the overall driving experience. The transient voltage suppression  diode  ( TVS ) is an efficient overvoltage protection device that quickly responds to transient overvoltage events, clamping the voltage to a safe level and protecting automotive electronics from damage. The SL ESD 5311N-2TR, as a high-performance  TVS   diode , has broad...

 Slkor LM393: A Cost-Effective Alternative to TI LM393DR and ONSEMI LM393DR2G V cc ：±18~36V V IO ：±3mV I IB ：25nA V I ：-0.3~36V T RE ：1.3μs Package：SOP-8 Description LM393 is an integrated circuit comprising two independent, high-precision voltage comparators, characterized by low offset voltage, with a maximum of 2.0mV. It is designed to operate over a wide voltage range with single-supply voltage, though it can also function with dual-supply voltage configurations. Moreover, it maintains low power consumption regardless of the supply voltage magnitude. One of its distinctive features is its ability to operate with a single-supply voltage, with the common-mode input voltage range of the comparators approaching ground level. The main applications of the LM393 include limiters, simple analog-to-digital converters, pulse generators, square wave generators, delay generators, wideband voltage-controlled oscillators, MOS clock timers, multi-frequency oscillators, and high-level digital ...
