Product details
Overview
SMCG150AHE3/57T 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 150 V stand-off voltage (VWM), 167–185 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (PPPM), 6.2 A peak pulse current (IPPM), and clamps transients to ≤243 V at rated surge. It is AEC-Q101 qualified and used in automotive power line and sensor interface protection.
For engineers reviewing the SMCG150AHE3/57T datasheet, SMCG150AHE3/57T pinout, SMCG150AHE3/57T application, or SMCG150AHE3/57T equivalent, this page delivers verified electrical specs, thermal resistance (RθJA = 75 °C/W), junction temperature range (−55 to +150 °C), polarity marking (cathode band), and AEC-Q101 qualification status - all critical for automotive-grade circuit protection design and BOM validation.
Technical Context
This TVS diode operates as a unidirectional clamping device with glass-passivated silicon junction, optimized for fast response (<1 ns) to 10/1000 µs surge waveforms. Its low incremental surge resistance and excellent clamping ratio (VC/VBR ≈ 1.46) ensure predictable voltage limiting during ESD and load-dump events.
The SMCG150AHE3/57T uses a DO-215AB surface-mount package with matte tin-plated leads, meets JESD201 Class 2 whisker resistance, and is rated for MSL Level 1 reflow (peak 260 °C). Thermal performance is specified with 8.0 mm × 8.0 mm copper pads per terminal, yielding RθJL = 15 °C/W and RθJA = 75 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 150 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working margin for 12 V/24 V automotive systems. |
| VBR (min/max) | 167 V / 185 V at IT = 1 mA - Confirmed breakdown threshold ensures reliable triggering above normal system transients. |
| VC @ IPPM | ≤243 V at 6.2 A - Clamping voltage under full 1500 W surge; determines maximum stress on downstream ICs. |
| PPPM | 1500 W - Peak pulse power handling with 10/1000 µs waveform; validates suitability for ISO 7637-2 Pulse 5a/b load-dump suppression. |
| TJ max. | +150 °C - Maximum junction temperature rating enables operation in under-hood automotive environments. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance measured on standard 8 mm × 8 mm pads; guides PCB copper area requirements. |
| AEC-Q101 | Qualified - Certified for automotive reliability per stress test requirements including HTGB, TCT, and HTRB. |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount, low-profile gull-wing leaded package with cathode band marking on one end. Dimensions: 7.87 mm × 3.17 mm × 2.41 mm (L × W × H); terminals are matte tin-plated, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal (unidirectional) | Connected to ground or low-side return path; conducts during forward surge events (e.g., reverse battery). |
| Cathode | Clamping output terminal (marked with band) | Connected to protected line (e.g., CAN_H, LIN, or 12 V rail); sinks surge current into ground when V > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood use with extended temperature cycling, high-temperature reverse bias, and humidity testing. |
| Glass-passivated junction | Ensures stable VBR over time and immunity to moisture-induced parameter drift in harsh environments. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 10605 ESD), improving clamping fidelity. |
| MSL Level 1 rating | Allows unlimited floor life and single-reflow compatibility up to 260 °C peak, simplifying SMT manufacturing. |
| UL 94 V-0 molding compound | Provides flame-retardant encapsulation required for automotive and industrial safety compliance. |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|

IC Role / Device Role / Timing Role: Standoff-rated TVS on feed line input, coordinated with upstream MOVs. Use Value: 150 V VWM matches telecom nominal voltage; 1500 W PPPM handles multi-kA induced surges without failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ150A-E3/57T | Same VWM (150 V), lower PPPM (400 W), SMA (DO-214AC) package, RθJA = 110 °C/W | Lower surge capacity; suitable only for non-load-dump, low-energy ESD scenarios | Select if space-constrained and surge energy < 100 mJ; not AEC-Q101 qualified. |
| SMCJ150AHE3/57T | Same VWM (150 V), higher PPPM (1500 W), SMC (DO-214AB) package, RθJA = 40 °C/W, AEC-Q101 qualified | Larger footprint but superior thermal dissipation; supports higher duty-cycle surges | Select for thermally demanding layouts or repeated surge exposure; requires larger PCB pad area. |
Compared with SMAJ150A-E3/57T, SMCG150AHE3/57T offers triple the surge power rating and automotive qualification; versus SMCJ150AHE3/57T, it trades 35 % smaller footprint for 88 % higher thermal resistance - favoring compactness over sustained power handling.

FAQ
What is the clamping voltage of SMCG150AHE3/57T under maximum rated surge?
The SMCG150AHE3/57T clamps to a maximum of 243 V when subjected to its rated 6.2 A peak pulse current (IPPM) using a 10/1000 µs waveform. This value is guaranteed per the datasheet's electrical characteristics table and defines the upper voltage limit imposed on protected circuitry during worst-case transients.
Is SMCG150AHE3/57T suitable for automotive applications?
Yes, SMCG150AHE3/57T is AEC-Q101 qualified and explicitly rated for automotive use. Its construction - glass-passivated junction, MSL Level 1 reflow compatibility, −55 °C to +150 °C operating range, and UL 94 V-0 molding - meets key requirements for engine control, body electronics, and ADAS subsystems.
What does the "HE3" suffix indicate in SMCG150AHE3/57T?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads. "H" indicates AEC-Q101 qualification, "E3" specifies RoHS compliance and industrial-grade reliability - distinct from "E3" alone (non-automotive) or "HM3" (halogen-free + AEC-Q101).
How does the SMCG (DO-215AB) package compare thermally to SMA or SMC packages?
The SMCG (DO-215AB) package has RθJA = 75 °C/W (on 8 mm × 8 mm pads), higher than SMC (DO-214AB, ~40 °C/W) but lower than SMA (DO-214AC, ~110 °C/W). This positions SMCG150AHE3/57T for moderate-power, space-constrained designs where footprint matters more than ultra-low thermal resistance.
Can SMCG150AHE3/57T be used in bidirectional configurations?
No - SMCG150AHE3/57T is unidirectional, as indicated by the "A" (not "CA") suffix. Bidirectional variants like SMCG150CA exist with symmetric clamping in both directions; using SMCG150AHE3/57T in reverse-biased configurations risks permanent junction damage due to lack of reverse breakdown specification.
