Product details
Overview
SMCG150A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) diode in DO-215AB (SMCG) package, featuring 150 V standoff voltage (VWM), 167–185 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and 6.2 A peak pulse current (IPPM) at 10/1000 µs waveform - designed for robust overvoltage protection of automotive power rails and industrial sensor interfaces.
For engineers reviewing the SMCG150A-E3/57T datasheet, SMCG150A-E3/57T pinout, SMCG150A-E3/57T application, or SMCG150A-E3/57T equivalent, key selection criteria include clamping voltage (VC = 243 V), AEC-Q101 qualification, MSL Level 1 rating, low incremental surge resistance, and compatibility with automated SMT assembly on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable breakdown behavior and fast response (<1 ns) to transients. Its thermal resistance (RθJA = 75 °C/W) and junction temperature range (−55 °C to +150 °C) support operation in under-hood automotive environments.
The device meets UL 497B recognition (QVGQ2) and complies with ANSI/IEEE C62.35 surge standards. It is rated for non-repetitive 8.3 ms half-sine surge current up to 200 A (IFSM), with clamping performance validated per 10/1000 µs waveform on standard PCB pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 150 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 167 V / 185 V at IT = 1.0 mA - ensures reliable turn-on within defined tolerance band |
| VC @ IPPM | 243 V at IPPM = 6.2 A - clamping voltage limits downstream IC stress during 10/1000 µs surge |
| PPPM | 1500 W - peak transient energy absorption capability under standardized surge waveform |
| ID @ VWM | 1.0 µA - ultra-low leakage preserves signal integrity and minimizes standby power loss |
| TJ max | +150 °C - enables deployment in high-temperature automotive and industrial control enclosures |
| MSL Level | Level 1 (J-STD-020) - supports lead-free reflow without moisture-induced damage |
Pinout & Package
Package: DO-215AB (SMCG), surface-mount gull-wing configuration with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode identified by molded band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to protected circuit ground or low-side rail | Provides reference path for clamping action; must be routed with low-inductance trace to minimize overshoot |
| Cathode | Current exit terminal in forward bias; marked with band; connects to line being protected | Acts as high-impedance input until VBR exceeded; defines polarity-sensitive placement on PCB |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| Glass passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a) |
| UL 497B recognized (QVGQ2) | Meets safety requirements for telecom and industrial signal-line protectors |
| RoHS-compliant, E3 suffix | Industrial-grade lead-free finish compatible with Pb-free reflow profiles up to 260 °C peak |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

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/VBR/PPPM ratings but in smaller SMA (DO-214AC) package; RθJA = 85 °C/W vs. 75 °C/W | Limited to lower average power dissipation; unsuitable for sustained surge duty cycles in engine bay | Select when board space is constrained and thermal margin exceeds 10 °C above SMCG150A-E3/57T capability |
| SMCJ150A-E3/57T | Higher PPPM (1500 W same), but larger SMC (DO-214AB) package; VBR tighter (167–179 V); RθJA = 65 °C/W | Better thermal performance but requires 30% more PCB area; not AEC-Q101 qualified | Prefer for industrial systems needing higher thermal headroom where automotive qualification is not required |
Compared with SMAJ150A-E3/57T and SMCJ150A-E3/57T, the SMCG150A-E3/57T uniquely balances AEC-Q101 compliance, DO-215AB footprint efficiency, and 75 °C/W thermal resistance - making it optimal for space-constrained automotive modules requiring validated reliability.

FAQ
What is the clamping voltage of SMCG150A-E3/57T and how is it measured?
The SMCG150A-E3/57T has a maximum clamping voltage (VC) of 243 V, measured at peak pulse current (IPPM) of 6.2 A using a standardized 10/1000 µs double-exponential surge waveform. This value is guaranteed per Vishay's test conditions on minimum recommended 8.0 mm × 8.0 mm copper pads, ensuring consistent protection margin for downstream ICs.
Is SMCG150A-E3/57T qualified for automotive use?
Yes, SMCG150A-E3/57T carries the HE3 suffix variant for AEC-Q101 qualification, and the E3 suffix version (SMCG150A-E3/57T) shares identical die and construction. Vishay documents full AEC-Q101 compliance for the SMCG150A family, including temperature cycling, HTRB, and ESD testing - confirming suitability for under-hood and chassis-mounted automotive modules.
What does the "57T" in SMCG150A-E3/57T indicate?
The "57T" denotes the preferred packaging code: 7-inch diameter plastic tape-and-reel format containing 850 units per reel. This delivery mode supports high-speed pick-and-place assembly and is specified in Vishay's ordering information table for the SMCG series, ensuring compatibility with standard SMT line feeders.
How does SMCG150A-E3/57T differ from bidirectional variants like SMCG150CA?
SMCG150A-E3/57T is unidirectional with cathode-band polarity, intended for DC rail protection where polarity is fixed. In contrast, SMCG150CA is bidirectional, lacks polarity marking, and provides symmetrical clamping for AC or floating lines. Their VBR and VC values differ slightly due to internal structure - SMCG150A-E3/57T has VBR = 167–185 V, while SMCG150CA is rated at 167–185 V bidirectionally per Vishay's datasheet Table 1.
What is the thermal resistance of SMCG150A-E3/57T and why does it matter?
SMCG150A-E3/57T 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. This value directly determines safe power derating - for example, at 85 °C ambient, the device can dissipate ~6.5 W continuously only if heatsinking matches the test condition; exceeding this risks thermal runaway during repeated surges.
