Product details
Overview
SMCG60A-E3/9AT 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 maximum clamping voltage (VC). It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics against inductive switching transients.
For engineers reviewing the SMCG60A-E3/9AT datasheet, SMCG60A-E3/9AT pinout, SMCG60A-E3/9AT application, or SMCG60A-E3/9AT equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, DO-215AB mechanical data, clamping performance under 10/1000 µs surge, and direct alternatives for circuit protection design-in.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, optimized for fast response (<1 ns) to transient overvoltages. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, critical for reliable suppression of ESD and load-dump events.
Rated for -55 °C to +150 °C junction temperature, it delivers 6.5 W steady-state power dissipation at TA = 50 °C and meets J-STD-020 MSL Level 1 with 260 °C reflow peak. The device is RoHS-compliant (E3 suffix) and qualified to AEC-Q101 for automotive-grade reliability.
Key Specifications

|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected circuitry. |
| VBR (min/max) | 66.7 V / 73.7 V at IT = 1 mA - Confirmed breakdown threshold window; ensures predictable turn-on during transients. |
| VC @ IPPM | 96 V at 15.5 A (10/1000 µs) - Clamped voltage seen by downstream components; limits stress on 60 V-rated ICs or MOSFETs. |
| PPPM | 1500 W - Peak transient energy absorption capability; supports robust protection against ISO 7637-2 Pulse 1/2a/5a in automotive systems. |
| ID @ VWM | 1.0 µA - Ultra-low leakage at rated stand-off; prevents parasitic loading on high-impedance sensor or bias networks. |
| TJ max. | +150 °C - Enables operation in under-hood automotive environments and industrial motor drive enclosures without derating. |
| RθJA | 75 °C/W - Thermal resistance informs PCB copper pad sizing (0.31" × 0.31") required to maintain junction temperature within limit at full power. |

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), lower PPPM (400 W), SMA (DO-214AC) package, higher RθJA (110 °C/W) | Limited to lower-energy transients; unsuitable for automotive load-dump or industrial surge immunity testing. | Select when cost or board space is constrained and peak surge energy remains below 400 W. |
| SMCJ60A-E3/9AT | Same VWM (60 V), higher PPPM (3000 W), identical DO-215AB package, but larger die and higher VC (103 V) | Provides double the surge capacity for harsher environments (e.g., commercial vehicle alternators), at expense of tighter clamping margin. | Choose when system-level testing requires >1500 W immunity and 103 V clamping is acceptable for downstream components. |
Compared with SMCG60A-E3/9AT, SMAJ60A-E3/57T offers reduced surge handling in a smaller footprint, while SMCJ60A-E3/9AT doubles power rating at the cost of higher clamping voltage-enabling tiered selection based on IEC 61000-4-5 level requirements and component voltage margins.

FAQ
What is the clamping voltage of SMCG60A-E3/9AT under a 10/1000 µs surge?
The SMCG60A-E3/9AT exhibits a maximum clamping voltage (VC) of 96 V when subjected to its rated peak pulse current of 15.5 A using the standardized 10/1000 µs waveform. This value is measured per JEDEC test conditions and guarantees that protected circuitry sees no more than 96 V during such transients, making SMCG60A-E3/9AT suitable for safeguarding 60 V-rated components like automotive gate drivers and industrial power controllers.
Is SMCG60A-E3/9AT qualified for automotive use?
Yes, SMCG60A-E3/9AT is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensor modules. The E3 suffix denotes RoHS compliance and industrial-grade construction, while the qualification covers stress tests for temperature cycling, humidity, and mechanical shock-ensuring long-term reliability in vehicular environments where SMCG60A-E3/9AT is deployed.
What package type does SMCG60A-E3/9AT use, and what are its mounting requirements?
SMCG60A-E3/9AT uses the SMCG (DO-215AB) surface-mount package with gull-wing leads and a cathode band marking. Per Vishay's datasheet, optimal thermal performance requires mounting on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. The device meets MSL Level 1 and supports 260 °C peak reflow, enabling direct integration into high-volume SMT lines without pre-baking-key for consistent manufacturing of assemblies using SMCG60A-E3/9AT.
How does the leakage current of SMCG60A-E3/9AT affect high-impedance circuits?
SMCG60A-E3/9AT specifies a maximum reverse leakage current (ID) of 1.0 µA at its 60 V stand-off voltage (VWM), ensuring negligible loading on high-impedance nodes such as sensor bias networks, precision reference dividers, or op-amp inputs. This low leakage preserves signal accuracy and power efficiency in battery-operated or low-noise measurement systems where SMCG60A-E3/9AT is applied for transient hardening without introducing offset or drift.
Can SMCG60A-E3/9AT replace SMAJ60A in an existing design?
No, SMCG60A-E3/9AT is not a drop-in replacement for SMAJ60A due to differing package (DO-215AB vs. DO-214AC), thermal resistance (75 °C/W vs. 110 °C/W), and surge capability (1500 W vs. 400 W). While both share 60 V VWM, the higher power rating and improved thermal performance of SMCG60A-E3/9AT require updated layout and thermal validation. Redesign is necessary if upgrading from SMAJ60A to SMCG60A-E3/9AT to ensure proper heat dissipation and mechanical fit.
