Product details
Overview
SM6S15-6003HE3/2D from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor in DO-218AB package, rated for 15 V stand-off voltage (VWM), 16.7–20.4 V breakdown (VBR), 26.9 V clamping at 171 A peak pulse current (10/1000 µs), and 4600 W peak pulse power. It is AEC-Q101 qualified and designed for automotive load dump protection.
For engineers reviewing the SM6S15-6003HE3/2D datasheet, SM6S15-6003HE3/2D pinout, SM6S15-6003HE3/2D application, or SM6S15-6003HE3/2D equivalent, key selection criteria include unidirectional polarity, 175 °C junction rating, low leakage (<10 µA at VWM), 0.95 °C/W thermal resistance, and ISO7637-2 compliance for automotive transients.
Technical Context
This TVS diode operates as a clamping device in series with the anode connected to the protected line and cathode grounded - its heatsink serves as the anode terminal. It delivers high surge robustness (600 A IFSM, 4600 W PPPM) under 10/1000 µs waveform while maintaining stable performance up to TJ = 175 °C.
The DO-218AB package enables high-power dissipation via metal heatsink mounting, with MSL Level 1 rating and JESD201 Class 2 whisker resistance. Its passivated anisotropic rectifier structure ensures low forward voltage drop (≤1.9 V at 100 A) and minimal leakage across temperature.

FAQ
What is the clamping voltage of SM6S15-6003HE3/2D at its rated peak pulse current?
The SM6S15-6003HE3/2D has a maximum clamping voltage (VC) of 26.9 V when subjected to its specified peak pulse current of 171 A under a 10/1000 µs waveform. This value is measured at TC = 25 °C and ensures downstream components see limited overvoltage during surge events. The SM6S15-6003HE3/2D maintains this clamping performance across its full operating temperature range due to its optimized passivated junction design.
Is SM6S15-6003HE3/2D suitable for automotive under-hood applications?
Yes, the SM6S15-6003HE3/2D is explicitly qualified to AEC-Q101 and rated for TJ = 175 °C, making it suitable for under-hood automotive applications such as engine control units and body control modules. Its DO-218AB package provides robust thermal coupling to heatsinks, and its ISO7637-2 compliance confirms suitability for load dump and switching transient protection. The SM6S15-6003HE3/2D meets MSL Level 1 and JESD201 Class 2 whisker resistance requirements for high-reliability assembly.
What does the "HE3/2D" suffix indicate in SM6S15-6003HE3/2D?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads meeting J-STD-002 and JESD22-B102 solderability standards, plus JESD201 Class 2 whisker resistance. The "/2D" indicates packaging in 13-inch plastic tape and reel, with 750 units per reel and anode orientation toward the sprocket hole. The "6003" is a Vishay internal revision code; the SM6S15-6003HE3/2D is functionally identical to SM6S15HE3/2D per datasheet 88384.
How does SM6S15-6003HE3/2D differ from bidirectional TVS diodes?
The SM6S15-6003HE3/2D is unidirectional only, with polarity defined by anode-to-heatsink and cathode-to-lead configuration - it conducts only during positive transients relative to ground. Bidirectional TVS devices (e.g., SMBJ15CA) protect both polarities but offer lower surge ratings and no AEC-Q101 qualification in comparable packages. The SM6S15-6003HE3/2D's unidirectional architecture enables higher power handling (4600 W) and tighter VBR tolerance, optimized for 12 V automotive rails.
What is the thermal resistance from junction to case for SM6S15-6003HE3/2D?
The SM6S15-6003HE3/2D has a typical thermal resistance of RθJC = 0.95 °C/W, measured from junction to the metal heatsink (cathode terminal). This low value enables effective heat transfer to the PCB copper pour or external heatsink, supporting continuous power dissipation up to 6 W at TC = 25 °C. Derating curves in the datasheet show usable power down to ~2.5 W at TC = 125 °C. The SM6S15-6003HE3/2D leverages the DO-218AB package's large metal slug to achieve this performance.
