Product details
Overview
SMCG60A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for high-energy surge protection with a 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR), and 1500 W peak pulse power (PPPM). It clamps transients to ≤96 V at 15.5 A IPPM and is AEC-Q101 qualified for automotive electronics.
For engineers reviewing the SMCG60A-E3/57T datasheet, SMCG60A-E3/57T pinout, SMCG60A-E3/57T application, or SMCG60A-E3/57T equivalent, this device is selected for robust overvoltage protection on power rails and signal lines where fast response (<1 ns), low clamping ratio (1.6× VWM), and MSL Level 1 reflow compatibility are required.
Technical Context
This TVS operates as a silicon avalanche diode with glass-passivated junction, delivering bidirectional-capable clamping behavior only in unidirectional configuration (cathode-banded polarity). Its 1500 W PPPM rating is specified under standardized 10/1000 µs waveform conditions with derating above 25 °C ambient per Fig. 2.
Thermal performance is defined by RθJA = 75 °C/W (on 8.0 mm × 8.0 mm copper pads) and RθJL = 15 °C/W, enabling reliable operation up to TJ = +150 °C. The device exhibits <1.0 µA reverse leakage at VWM and supports 200 A IFSM (8.3 ms half-sine) for infrequent surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe DC/AC rail margin. |
| VBR min/max | 66.7 V / 73.7 V - Breakdown occurs within this range at 1 mA test current; ensures predictable turn-on threshold. |
| VC @ IPPM | ≤96 V - Clamped voltage at 15.5 A peak pulse current; determines maximum stress imposed on protected IC. |
| PPPM | 1500 W - Peak transient energy absorption capability under 10/1000 µs waveform; meets IEC 61000-4-5 Level 4. |
| ID @ VWM | ≤1.0 µA - Reverse leakage at rated stand-off voltage; minimizes standby power loss in battery-powered systems. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments. |
| Package | SMCG (DO-215AB) - Low-profile SMD outline with gull-wing leads; compatible with automated placement and J-STD-020 reflow. |
Pinout & Package
SMCG60A-E3/57T uses the SMCG (DO-215AB) surface-mount package: 2-terminal gull-wing leaded case with cathode band marking on the unidirectional variant. Dimensions: 7.87 mm × 10.16 mm × 2.41 mm (L × W × H); compliant with UL 94 V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |

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/VBR/PPPM specs but in SMA (DO-214AC) package; 20 % larger footprint and 2× higher RθJA (140 °C/W). | Limited to lower-power or non-automotive designs due to reduced thermal performance and no AEC-Q101 qualification. | Select when board space allows larger package and automotive qualification is not required. |
| SMCJ60A-E3/57T | Higher PPPM (1500 W same), but wider VBR range (66.7–83.3 V); identical SMCG package and AEC-Q101 rating. | Better suited for systems requiring margin against VBR drift over temperature or lifetime; slightly higher clamping voltage (≤103 V). | Choose when tighter VBR tolerance is less critical than extended surge endurance under repeated stress. |

FAQ
What is the clamping voltage of SMCG60A-E3/57T at its rated peak pulse current?
The SMCG60A-E3/57T has a maximum clamping voltage (VC) of 96 V when subjected to its rated peak pulse current (IPPM) of 15.5 A under the standard 10/1000 µs waveform. This value is measured at the device terminals with recommended PCB pad layout (8.0 mm × 8.0 mm copper), ensuring realistic system-level protection performance for the SMCG60A-E3/57T.
Is SMCG60A-E3/57T suitable for automotive applications?
Yes, SMCG60A-E3/57T carries AEC-Q101 qualification, confirming compliance with stress tests for automotive-grade reliability-including temperature cycling, high-temperature operating life, and mechanical shock. Its SMCG (DO-215AB) package, MSL Level 1 rating, and +150 °C TJ max make it appropriate for under-hood and body-control module deployments using the SMCG60A-E3/57T.
How does the E3 suffix affect SMCG60A-E3/57T's compliance and plating?
The E3 suffix indicates RoHS-compliant construction with matte tin-plated leads, verified per J-STD-002 and JESD 22-B102 for solderability. It also confirms compliance with JEDEC JESD201 Class 2 whisker resistance testing. This makes SMCG60A-E3/57T suitable for lead-free reflow assembly without compromising intermetallic joint integrity-critical for long-term reliability of the SMCG60A-E3/57T.
What is the thermal resistance from junction to ambient for SMCG60A-E3/57T?
The typical junction-to-ambient thermal resistance (RθJA) for SMCG60A-E3/57T is 75 °C/W, measured on the minimum recommended 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pad layout per terminal. This value enables accurate thermal modeling when designing PCB layouts for sustained power dissipation or repetitive surge duty cycles involving the SMCG60A-E3/57T.
Can SMCG60A-E3/57T be used in bidirectional configurations?
No-SMCG60A-E3/57T is a unidirectional TVS diode, identified by its cathode band marking. Bidirectional variants in the same family carry the "CA" suffix (e.g., SMCG60CA). Using SMCG60A-E3/57T in reverse-biased AC applications would result in forward conduction and potential failure; always verify polarity during placement of the SMCG60A-E3/57T.
