Product details
Overview
SMCG60AHE3/9AT from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMCG (DO-215AB) package, featuring a 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), 15.5 A peak pulse current (IPPM), and 96 V clamping voltage (VC). It is AEC-Q101 qualified and used for automotive-level ESD and surge protection on power rails and signal lines feeding MOSFETs or microcontrollers.
For engineers reviewing the SMCG60AHE3/9AT datasheet, SMCG60AHE3/9AT pinout, SMCG60AHE3/9AT application, or SMCG60AHE3/9AT equivalent, this page delivers verified electrical parameters, mechanical package data, real-world protection use cases, and validated alternative parts - all aligned to Vishay's 88457 specification revision dated 09-Jan-2024.
Technical Context
This TVS operates as a unidirectional clamping device with cathode-band polarity marking, designed to shunt transient energy above its breakdown threshold while maintaining low leakage (<1.0 µA at VWM) and fast response time. Its glass-passivated junction ensures stable performance under repetitive surge stress.
Rated for 150 °C maximum junction temperature and 75 °C/W junction-to-ambient thermal resistance, it relies on 8.0 mm × 8.0 mm copper pad layout per terminal for full 1500 W pulse power capability. The device meets MSL Level 1 and is qualified to AEC-Q101 for automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC rail margin. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown range ensuring reliable turn-on during transients without premature conduction. |
| VC @ IPPM | 96 V at 15.5 A - Clamping voltage under 10/1000 µs surge; determines maximum voltage seen by protected IC during worst-case event. |
| PPPM | 1500 W - Peak pulse power handling capacity; enables robust protection against ISO 7637-2 Pulse 1/2/5a and IEC 61000-4-5 surges. |
| ID @ VWM | ≤1.0 µA - Reverse leakage current at rated stand-off voltage; ensures minimal power loss and signal integrity in high-impedance circuits. |
| TJ max. | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive environments. |
| RθJA | 75 °C/W - Thermal resistance from junction to ambient on standard 8 mm × 8 mm pads; informs heatsinking requirements for sustained power dissipation. |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount, low-profile gull-wing leaded case with matte tin-plated terminals, UL 94 V-0 molding compound, and AEC-Q101 qualification. Polarity marked by cathode band on unidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction (unidirectional only) | Connected to ground or lower-potential node; forms clamping path when cathode is at higher potential. |
| Cathode | Current exit point during clamping; marked with band | Connected to protected line (e.g., 12 V rail); conducts surge current to ground when transient exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity bias, and surge endurance per JESD47. |
| Glass passivated junction | Ensures stable VBR and low leakage over lifetime, even under high-humidity or high-temperature stress conditions. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving clamping precision for sensitive 3.3 V or 5 V logic interfaces. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning; eliminates moisture-related popcorning risk. |
| 1500 W 10/1000 µs pulse rating | Supports protection against severe load-dump and inductive switching events common in 12 V/24 V vehicle systems. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and cable discharge events in factory automation. IC Role / Device Role / Timing Role: Low-leakage (≤1 µA) TVS mounted at connector interface to absorb ±8 kV contact ESD per IEC 61000-4-2. Use Value: Maintains signal integrity below 60 V stand-off while clamping sub-100 ns transients without loading the 100 kΩ sensor output impedance. |
| Motor Drive Gate Protection | Telecom Line Surge Suppression |
Use Scenario: Safeguarding high-side N-channel MOSFET gates driven by isolated gate drivers in BLDC inverters. IC Role / Device Role / Timing Role: Fast-response TVS placed between gate and source to clamp Miller-induced voltage spikes during switching transitions. Use Value: With 96 V clamping and <1 ns response, prevents gate oxide rupture while allowing normal 10–15 V gate drive swing. |
Use Scenario: Front-end surge suppression on PoE-powered Ethernet ports exposed to lightning-induced surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Primary unidirectional TVS on DC input side of PD controller, coordinated with secondary GDT or MOV stages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A-E3/57T | Same VWM (60 V), but lower PPPM (400 W) and smaller SMA (DO-214AC) package; RθJA = 100 °C/W. | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or high-current load dump. | Select when board space is constrained and surge threat level is limited to IEC 61000-4-2/4-4 only. |
| SMCJ60AHE3/9AT | Identical VWM, VBR, VC, and PPPM (1500 W), but in larger SMC (DO-214AB) package with higher IFSM (200 A vs. same). | Offers identical clamping performance with greater surge endurance margin and better thermal mass for repeated events. | Prefer when long-term reliability under cyclic surge stress is critical, despite larger footprint. |
Compared with SMCG60AHE3/9AT, SMAJ60A-E3/57T trades surge capacity for compactness, while SMCJ60AHE3/9AT delivers identical protection with enhanced thermal robustness in a larger footprint - enabling design flexibility based on space versus lifetime reliability trade-offs.

FAQ
What is the clamping voltage of SMCG60AHE3/9AT under a 10/1000 µs surge?
The SMCG60AHE3/9AT has a maximum clamping voltage (VC) of 96 V at 15.5 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's Document Number 88457, ensuring predictable voltage limiting during surge events without exceeding safe thresholds for downstream 60 V-rated components.
Is SMCG60AHE3/9AT suitable for automotive applications?
Yes, SMCG60AHE3/9AT is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments up to +150 °C junction temperature. Its DO-215AB package, MSL Level 1 rating, and 1500 W surge capability meet requirements for ISO 7637-2 load dump and inductive switching protection in ECUs, body controllers, and ADAS modules.
What does the "HE3" suffix indicate in SMCG60AHE3/9AT?
The "HE3" suffix in SMCG60AHE3/9AT denotes RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering nomenclature, HE3 identifies the industrial-grade, halogen-free, and automotive-qualified variant - distinct from E3 (RoHS, non-automotive) and HM3 (halogen-free + AEC-Q101).
How does the SMCG60AHE3/9AT package differ from SMAJ or SMCJ series packages?
SMCG60AHE3/9AT uses the SMCG (DO-215AB) package - a gull-wing variant with 0.058" lead width and 0.310" body length - offering lower profile and improved thermal performance over SMA (DO-214AC) while occupying less PCB area than SMC (DO-214AB). Its RθJA is 75 °C/W (vs. 100 °C/W for SMAJ and 60 °C/W for SMCJ), balancing size and thermal efficiency.
What is the maximum reverse leakage current for SMCG60AHE3/9AT at its rated VWM?
The SMCG60AHE3/9AT exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 60 V stand-off voltage (VWM), measured at TA = 25 °C. This low leakage preserves power efficiency in always-on automotive modules and avoids false triggering in high-impedance sensor bias networks, as verified in Table 1 of Vishay's 88457 datasheet.
