Product details
Overview
SMCG100AHE3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for high-energy surge protection on power and signal lines. It features a 100 V stand-off voltage (VWM), 111–123 V breakdown voltage (VBR), 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 rail and sensor interface protection.
For engineers reviewing the SMCG100AHE3/57T datasheet, SMCG100AHE3/57T pinout, SMCG100AHE3/57T application, or SMCG100AHE3/57T equivalent, this page delivers verified electrical specs, mechanical package data, real-world use cases, and validated alternative parts - all aligned with Vishay's 88457 revision (Jan 2024) specification sheet.
Technical Context
The SMCG100AHE3/57T operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology for stable breakdown and low incremental surge resistance. Its 10/1000 µs waveform response enables sub-nanosecond clamping action during ESD or lightning-induced transients.
Designed for surface-mount automated placement, it meets J-STD-020 MSL level 1 (260 °C peak reflow) and supports bidirectional variants via CA suffix - though SMCG100AHE3/57T itself is unidirectional with cathode band marking. Thermal resistance is RθJA = 75 °C/W on 8.0 mm × 8.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 111 V / 123 V at 1 mA test current - defines reliable avalanche onset window |
| VC @ IPPM | ≤162 V at 9.3 A - clamping voltage under full 1500 W surge ensures downstream IC safety |
| PPPM | 1500 W - peak pulse power handling capability per 10/1000 µs waveform |
| ID @ VWM | ≤1.0 µA - ultra-low leakage preserves system efficiency in standby modes |
| TJ max | +150 °C - extended junction temperature rating supports under-hood automotive deployment |
| Package | SMCG (DO-215AB) - low-profile SMD outline with matte tin-plated leads, RoHS-compliant and AEC-Q101 qualified |
Pinout & Package
SMCG100AHE3/57T uses the SMCG (DO-215AB) surface-mount package: 2-terminal gull-wing leaded case with cathode band marking on the unidirectional device. Dimensions are 7.87 mm × 10.16 mm × 2.41 mm (L × W × H); terminals are matte tin-plated and solderable per J-STD-002/JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to protected circuit ground or low-side reference | Must be routed to lowest-impedance ground plane to minimize clamping overshoot during surge events |
| Cathode | Current exit terminal in forward bias; marked by band; connects to line being protected | Band orientation identifies polarity - critical for correct placement on power/signal rails |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity, and surge endurance |
| Glass-passivated junction | Ensures stable VBR over lifetime and immunity to moisture-induced parameter drift |
| MSL Level 1 rating | Enables single-reflow assembly without baking; compatible with standard SMT production lines |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a) |
| UL 94 V-0 molding compound | Provides flame-retardant housing required for automotive and industrial safety certifications |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface |
|---|---|

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, RθJA = 110 °C/W | Lower surge capacity; suitable only for light-duty consumer interfaces, not automotive load dump | Select when board space is constrained and surge energy is <400 W; verify thermal margin with smaller pad layout |
| SMCJ100A-E3/57T | Same VWM (100 V), higher PPPM (1500 W), larger SMC (DO-214AB) package, RθJA = 50 °C/W | Better thermal performance but requires ~3× PCB area; not AEC-Q101 qualified in E3 variant | Choose for industrial power supplies needing superior thermal headroom; confirm qualification status if automotive use is intended |
Compared with SMAJ100A-E3/57T and SMCJ100A-E3/57T, SMCG100AHE3/57T uniquely combines AEC-Q101 qualification, 1500 W surge rating, and compact DO-215AB footprint - making it optimal for space-constrained automotive modules requiring certified reliability.

FAQ
What is the clamping voltage of SMCG100AHE3/57T at its rated peak pulse current?
The SMCG100AHE3/57T clamps to a maximum of 162 V at its rated 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 per terminal and reflects worst-case voltage seen by downstream circuitry during surge events - a key parameter for ensuring safe operation of protected ICs and power stages.
Is SMCG100AHE3/57T suitable for bidirectional signal line protection?
No - SMCG100AHE3/57T is a unidirectional TVS diode, identified by its cathode band marking and specified breakdown behavior in one polarity only. For bidirectional protection, Vishay offers the SMCG100CA variant. Using SMCG100AHE3/57T on AC-coupled or differential lines without proper polarity alignment may result in unintended conduction or failure to suppress negative-going transients.
Does SMCG100AHE3/57T require derating at elevated ambient temperatures?
Yes - SMCG100AHE3/57T must be derated above TA = 25 °C per Figure 2 in Vishay document 88457. At 85 °C ambient, its peak pulse power drops to approximately 750 W (50% derating), and at 125 °C, it falls to ~300 W. Designers must apply these derating curves when sizing for under-hood or enclosed industrial environments where sustained high temperatures occur.
What does the "HE3" suffix indicate in SMCG100AHE3/57T?
The "HE3" suffix in SMCG100AHE3/57T denotes RoHS-compliant construction with AEC-Q101 qualification - distinguishing it from base "E3" (RoHS, industrial grade) and "HM3" (halogen-free + AEC-Q101) variants. This suffix confirms that SMCG100AHE3/57T has passed automotive-specific stress tests including temperature cycling, humidity, and surge endurance, making it appropriate for qualified automotive applications.
Can SMCG100AHE3/57T be used in place of SMAJ100A in an existing design?
No - while both share 100 V VWM, SMCG100AHE3/57T has higher surge capability (1500 W vs. 400 W) and different thermal characteristics (RθJA = 75 °C/W vs. 110 °C/W), requiring updated thermal layout and potentially revised PCB trace routing. Additionally, SMCG100AHE3/57T uses DO-215AB packaging versus SMA (DO-214AC), so direct replacement would necessitate footprint redesign and requalification per AEC-Q101 if used in automotive systems.
