Product details
Overview
SMCG100AHE3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 100 V stand-off voltage (VWM), 111–123 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (PPPM), 9.3 A peak pulse current (IPPM), and clamps to 162 V at rated surge. It is AEC-Q101 qualified and used in automotive power line and sensor interface protection.
For engineers reviewing the SMCG100AHE3/9AT datasheet, SMCG100AHE3/9AT pinout, SMCG100AHE3/9AT application, or SMCG100AHE3/9AT equivalent, this page delivers verified electrical parameters, mechanical package details, real-world use cases, and validated alternative parts - all aligned with Vishay's 88457 specification revision (Jan 2024).
Technical Context
The SMCG100AHE3/9AT operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology for stable clamping under fast transients (10/1000 µs waveform). Its low incremental surge resistance and 162 V clamping voltage at 9.3 A ensure predictable energy diversion during ESD or load-dump events.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads, it achieves 75 °C/W junction-to-ambient thermal resistance and supports operation from –55 °C to +150 °C. The cathode-band marking confirms polarity, and its RoHS-compliant matte tin terminals meet J-STD-002 solderability standards.

Pinout & Package
SMCG100AHE3/9AT uses the SMCG (DO-215AB) package: a gull-wing surface-mount outline with two terminals, cathode marked by a band. Mounting requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal per Vishay spec.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to protected circuit ground or low-side return path | Provides reference node for clamping action; must be routed with low-inductance path to system ground |
| Cathode | Current exit point in forward bias; marked by visible band on device body | Connected to line being protected (e.g., 12 V rail); determines unidirectional conduction direction |
Key Features

| 1500 W PPPM rating | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-earth) in properly designed layouts |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump (ISO 7637-2 Pulse 5a) and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges above 100 V. Use Value: Limits rail voltage to ≤162 V during 1500 W transients, preventing damage to MCU power supplies and CAN transceivers. | Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) in factory automation systems exposed to relay switching noise. IC Role / Device Role / Timing Role: TVS mounted at connector entry point to shunt inductive kickback from nearby solenoids or motors. Use Value: Sub-10 ns response time and 162 V clamping prevent latch-up or parametric shift in precision ADC front-ends. |
| Telecom DC Power Feeds | Consumer Power Adapter Outputs |
Use Scenario: Securing -48 V telecom rectifier outputs against lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Reverse-biased unidirectional TVS referenced to negative rail, absorbing positive-going transients. Use Value: 100 V VWM allows safe operation across full -48 V ±10 % tolerance while clamping >100 V spikes to 162 V. | Use Scenario: Adding secondary-level surge protection on 5–24 V USB-C PD or wall adapter outputs. IC Role / Device Role / Timing Role: Final-stage TVS on output rail, downstream of primary OVP and filtering, to catch residual transients. Use Value: AEC-Q101 qualification and 1500 W rating provide margin beyond IEC 62368-1 requirements for end-product safety certification. |
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 | Same VWM (100 V), lower PPPM (400 W), SMA (DO-214AC) package, non-AEC-Q101 | Not qualified for automotive; suitable only for industrial/commercial grade designs with lower surge stress | Select when cost sensitivity outweighs automotive qualification and 1500 W surge headroom is unnecessary |
| SMCJ100AHE3/9AT | Same VWM (100 V), same AEC-Q101 qualification, identical DO-215AB (SMCG) package, but 1500 W rating achieved with higher VC (170 V) | Higher clamping voltage reduces protection margin for 3.3 V or 5 V logic rails downstream | Prefer SMCG100AHE3/9AT where tighter clamping (162 V vs. 170 V) is critical for protecting low-voltage interfaces |
Compared with SMAJ100A-E3/57T and SMCJ100AHE3/9AT, the SMCG100AHE3/9AT delivers superior clamping performance (162 V) within an AEC-Q101-qualified DO-215AB footprint - making it optimal for space-constrained automotive modules requiring both high surge capacity and precise voltage limiting.

FAQ
What is the clamping voltage of SMCG100AHE3/9AT at its rated peak pulse current?
The SMCG100AHE3/9AT clamps to 162 V at its specified peak pulse current of 9.3 A (10/1000 µs waveform). This value is measured under standardized test conditions with 0.31" × 0.31" copper pads and represents the maximum voltage seen by the protected circuit during a full-rated surge event. The SMCG100AHE3/9AT maintains this clamping performance across its qualified temperature range.
Is SMCG100AHE3/9AT suitable for automotive applications?
Yes, SMCG100AHE3/9AT is AEC-Q101 qualified and explicitly rated for automotive use. Its construction - including glass-passivated junction, MSL Level 1 reflow compatibility, and operation from –55 °C to +150 °C - meets automotive reliability requirements. The SMCG100AHE3/9AT is commonly deployed in engine control modules, body control units, and ADAS sensor interfaces where load dump and ESD protection are critical.
What does the "HE3" suffix indicate in SMCG100AHE3/9AT?
The "HE3" suffix in SMCG100AHE3/9AT denotes RoHS-compliant construction with AEC-Q101 qualification. Specifically, "H" indicates AEC-Q101 qualification, "E3" signifies RoHS compliance and industrial-grade reliability. This distinguishes it from base variants like "E3" (RoHS only) or "HM3" (halogen-free + AEC-Q101). The SMCG100AHE3/9AT thus carries dual environmental and automotive certifications.
How does SMCG100AHE3/9AT differ from SMCG100A-E3/9AT?
SMCG100AHE3/9AT includes AEC-Q101 qualification ("H"), whereas SMCG100A-E3/9AT lacks automotive qualification. Both share identical electrical specs (VWM = 100 V, PPPM = 1500 W, VC = 162 V) and DO-215AB packaging, but only SMCG100AHE3/9AT is approved for automotive applications. For non-automotive industrial use, SMCG100A-E3/9AT may be selected to reduce cost, but the SMCG100AHE3/9AT is required where AEC-Q101 compliance is mandated.
What is the thermal resistance of SMCG100AHE3/9AT, and how does it affect PCB layout?
The SMCG100AHE3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. To maintain safe operation under repeated surges, designers must adhere to this pad layout - reducing RθJA improves power dissipation and prevents thermal runaway. The SMCG100AHE3/9AT's RθJL of 15 °C/W further emphasizes the need for solid thermal connection to internal ground planes.
