Product details
Overview
SMCG6.0AHE3/57T 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 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (PPPM), 145.6 A peak pulse current (IPPM), and clamps to 10.3 V at IPPM - ideal for protecting MOSFETs, ICs, and sensor signal lines in automotive and industrial power rails.
For engineers reviewing the SMCG6.0AHE3/57T datasheet, SMCG6.0AHE3/57T pinout, SMCG6.0AHE3/57T application, or SMCG6.0AHE3/57T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 1500 W surge capability with 10/1000 µs waveform, low clamping ratio (VC/VBR ≈ 1.48), and RoHS-compliant HE3 suffix indicating automotive-grade reliability and MSL Level 1 moisture sensitivity.
Technical Context
This TVS diode operates as a clamping device in series with power or signal paths, activating when reverse voltage exceeds VBR to divert surge energy away from protected components. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while the DO-215AB package supports automated SMT placement and meets UL 94 V-0 flammability requirements.
The SMCG6.0AHE3/57T is rated for -55 °C to +150 °C operating junction temperature, has 75 °C/W junction-to-ambient thermal resistance (RθJA), and is specified for non-repetitive 10/1000 µs surges on 8.0 mm × 8.0 mm copper pads - enabling reliable transient suppression in high-reliability automotive ECUs and industrial motor drives without external heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum continuous reverse working voltage before clamping begins; sets upper limit for normal operation in 5 V rail protection. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - defines precise conduction threshold; tight 10.4% tolerance enables predictable turn-on behavior. |
| VC @ IPPM | 10.3 V at 145.6 A - clamping voltage under full 1500 W surge; limits stress on downstream ICs during ISO 7637-2 Pulse 1/2a events. |
| PPPM | 1500 W - peak pulse power handling with 10/1000 µs waveform; supports automotive load-dump and inductive switching transients. |
| ID @ VWM | 1000 µA max - low reverse leakage at stand-off voltage preserves power efficiency in always-on circuits. |
| TJ max | +150 °C - extended junction temperature rating allows use in under-hood automotive environments without derating. |
| AEC-Q101 | Qualified - validated for automotive electronic systems per stress test requirements including HTOL, TCT, and ESD. |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount, low-profile gull-wing leaded package with matte tin-plated terminals, UL 94 V-0 molding compound, and polarity indicated by cathode band. Complies with J-STD-002/JESD 22-B102 solderability and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to ground or lower-potential node in unidirectional configuration. | Provides reference path for surge current return; must be routed with low-inductance trace to minimize clamping overshoot. |
| Cathode | Current exit terminal in forward bias; marked with band; connected to protected line (e.g., 5 V supply or CAN_H). | Acts as the "protected side" node; voltage at this terminal is clamped to ≤10.3 V during transients. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood applications including engine control, body electronics, and ADAS sensors. |
| Glass-passivated junction | Ensures stable VBR and low leakage over temperature and lifetime; eliminates risk of junction degradation under repeated surges. |
| Low incremental surge resistance | Minimizes VC rise during high-current transients, improving clamping precision and reducing stress on protected ICs. |
| MSL Level 1 (260 °C peak) | Enables standard reflow assembly without baking; compatible with high-volume automotive PCB manufacturing. |
| 1500 W 10/1000 µs rating | Meets ISO 7637-2 Pulse 5a (load dump) requirements for 12 V systems with up to 300 V/100 ms surges. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|

Use Value: Enables compliance with IEC 61000-4-5 Level 3 (1 kV line-earth) with minimal board space and no active circuitry. | Use Scenario: Protecting PoE-powered devices (e.g., IP cameras) from surges induced on 48 V DC feeding lines in outdoor telecom cabinets. IC Role / Device Role / Timing Role: Unidirectional TVS installed on each DC feed pair to clamp common-mode and differential surges. Use Value: Withstands repetitive 10/1000 µs surges up to 1500 W while maintaining low leakage (<1 mA) to avoid quiescent current drain. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/52T | Same VWM (6.0 V) and PPPM (400 W), but lower 400 W rating and SMA (DO-214AC) package; RθJA = 85 °C/W. | Not AEC-Q101 qualified; suitable for commercial-grade consumer power supplies, not automotive. | Select only if cost-sensitive and AEC-Q101 or 1500 W surge capability is not required. |
| SMCJ6.0AHE3/57T | Same VWM (6.0 V), AEC-Q101, HE3 suffix, and DO-214AB package; higher PPPM (3000 W) and larger footprint. | Requires more PCB area; better suited for heavy-duty industrial motor drives with higher surge exposure. | Choose when >1500 W surge margin is needed and board space permits larger SMC package. |
Compared with SMAJ6.0A-E3/52T and SMCJ6.0AHE3/57T, the SMCG6.0AHE3/57T uniquely balances automotive qualification, 1500 W surge capacity, and compact DO-215AB footprint - making it optimal for space-constrained AEC-Q101 designs where 3000 W is excessive and 400 W is insufficient.

FAQ
What is the clamping voltage of SMCG6.0AHE3/57T and how is it measured?
The SMCG6.0AHE3/57T has a maximum clamping voltage (VC) of 10.3 V at its rated peak pulse current (IPPM) of 145.6 A, tested with a 10/1000 µs waveform per IEC 61000-4-5. This value is measured across the cathode and anode terminals under standardized surge conditions and reflects the actual voltage seen by protected circuitry during worst-case transients - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is SMCG6.0AHE3/57T suitable for automotive applications?
Yes, SMCG6.0AHE3/57T is AEC-Q101 qualified and carries the HE3 suffix, confirming its suitability for automotive applications including engine control modules, body control units, and ADAS sensor interfaces. It operates from -55 °C to +150 °C, withstands 1500 W surges, and meets MSL Level 1 reflow requirements - fulfilling key reliability and manufacturability demands for under-hood and chassis-mounted electronics.
What does the "HE3" suffix mean in SMCG6.0AHE3/57T?
The "HE3" suffix in SMCG6.0AHE3/57T indicates RoHS-compliant construction with AEC-Q101 qualification and industrial-grade reliability. Per Vishay's ordering nomenclature, HE3 denotes halogen-free material content, automotive qualification, and compliance with JESD 201 Class 2 whisker resistance - distinguishing it from E3 (RoHS, non-automotive) and HM3 (halogen-free + AEC-Q101) variants.
How does SMCG6.0AHE3/57T differ from bidirectional TVS diodes like SMCG6.0CAHE3/57T?
SMCG6.0AHE3/57T is unidirectional and intended for DC line protection (e.g., 5 V supply to ground), with polarity marked by a cathode band. In contrast, SMCG6.0CAHE3/57T is bidirectional, has no polarity marking, and protects AC or symmetrical signal lines. Their VWM (6.0 V) and PPPM (1500 W) match, but SMCG6.0AHE3/57T supports forward conduction and is optimized for power rail clamping, whereas the CA version handles bipolar transients.
What is the thermal resistance of SMCG6.0AHE3/57T and how does it affect layout?
The SMCG6.0AHE3/57T 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 assumes minimum recommended pad layout; reducing pad size increases thermal impedance and may require derating during repetitive surge events. Layout must maintain full copper fill under both leads and avoid thermal isolation to ensure reliable operation at TJ = 150 °C.
