Product details
Overview
SMCJ100AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 100 V standoff voltage, 1500 W peak pulse power, and 162 V clamping voltage at 9.3 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning-induced surges in automotive and industrial power electronics.
For engineers reviewing the SMCJ100AHE3_A/I datasheet, SMCJ100AHE3_A/I pinout, SMCJ100AHE3_A/I application, or SMCJ100AHE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 1500 W 10/1000 µs surge rating, low 0.107 %/°C VBR temperature coefficient, and RoHS-compliant matte tin-plated leads solderable per J-STD-002.
Technical Context
The SMCJ100AHE3_A/I operates as a clamping-type TVS diode with avalanche breakdown behavior, triggered when reverse voltage exceeds its 111–123 V breakdown range at 1 mA test current. Its glass-passivated junction ensures stable leakage performance (<1.0 µA at 100 V) and fast sub-nanosecond response to transient events.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads, it delivers 1500 W peak pulse power under 10/1000 µs waveform while maintaining thermal resistance of 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-lead), enabling reliable operation up to 150 °C junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A-E3/57T | Lower 400 W PPPM, SMA package (smaller footprint, higher RθJA) | Not suitable for 1500 W surge environments; limited to lower-energy interfaces | Select only if space-constrained and surge threat level is ≤400 W |
| SMCJ100CAHE3_A/I | Bidirectional variant with same VWM/VC, symmetric clamping in both polarities | Required for AC-coupled or floating signal lines where polarity reversal may occur | Choose bidirectional version only when protecting differential pairs or ungrounded buses |
Compared with SMAJ100A-E3/57T and SMCJ100CAHE3_A/I, the SMCJ100AHE3_A/I uniquely balances 1500 W surge capacity, AEC-Q101 qualification, and SMC package thermal performance-making it optimal for automotive and industrial DC power rail protection where high-energy transients and long-term reliability are critical.

FAQ
What is the breakdown voltage range of the SMCJ100AHE3_A/I?
The SMCJ100AHE3_A/I has a guaranteed breakdown voltage (VBR) range of 111 V to 123 V at 1 mA test current, measured per ANSI/IEEE C62.35 standards. This range defines the minimum and maximum voltage at which the device enters avalanche conduction, ensuring predictable clamping behavior across manufacturing lots and temperature extremes. The SMCJ100AHE3_A/I's specified VBR confirms its suitability for 100 V nominal systems where margin above operating voltage is required.
Is the SMCJ100AHE3_A/I AEC-Q101 qualified?
Yes, the SMCJ100AHE3_A/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in revision 09-Jan-2024 of document 88394. This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock-validating its use in automotive powertrain and chassis modules. The SMCJ100AHE3_A/I meets the full AEC-Q101 stress test profile, not just partial compliance.
What is the clamping voltage of the SMCJ100AHE3_A/I at its rated peak pulse current?
The SMCJ100AHE3_A/I clamps to a maximum of 162 V at its rated peak pulse current of 9.3 A, measured under the standard 10/1000 µs waveform. This clamping voltage represents the worst-case voltage imposed on the protected circuit during a full 1500 W transient event. The SMCJ100AHE3_A/I's 162 V VC ensures downstream components rated for ≥165 V withstand the surge without failure.
Does the SMCJ100AHE3_A/I have polarity marking, and how is it identified?
Yes, the SMCJ100AHE3_A/I is unidirectional and features a visible cathode band on the body-consistent with DO-214AB package conventions. The banded end is the cathode and must be connected toward the protected line; the opposite end is the anode, typically tied to ground. This marking is laser-etched or molded into the epoxy case and remains legible after reflow soldering. The SMCJ100AHE3_A/I's polarity marking eliminates misorientation risk during automated placement.
What is the thermal resistance specification for the SMCJ100AHE3_A/I?
The SMCJ100AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15 °C/W, measured on 8.0 mm × 8.0 mm copper pads per JEDEC standards. These values define heat dissipation limits under steady-state and pulsed conditions. For the SMCJ100AHE3_A/I, RθJA = 75 °C/W means a 6.5 W continuous power dissipation raises junction temperature by 488 °C above ambient-hence derating is essential, and the device relies on transient energy absorption rather than continuous power handling.
