Product details
Overview
SMCG36-E3/57T from Vishay General Semiconductor is a bi-directional surface-mount Transient Voltage Suppressor (TVS) in DO-215AB (SMCG) package, rated for 36 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), and clamps to 58.1 V at 25.8 A peak pulse current (IPPM). It protects signal lines and power rails in automotive sensor units and industrial control interfaces against ESD and inductive switching transients.
For engineers reviewing the SMCG36-E3/57T datasheet, SMCG36-E3/57T pinout, SMCG36-E3/57T application, or SMCG36-E3/57T equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 150 °C junction temperature rating, low incremental surge resistance, and compatibility with automated SMT placement on standard PCB pads.
Technical Context
This device operates as a bi-directional avalanche diode, exhibiting symmetrical breakdown behavior in both polarities with no polarity marking. Its glass-passivated junction enables fast response time (<1 ns) and stable clamping under repetitive transient stress.
Designed for mounting on 8.0 mm × 8.0 mm copper pads per terminal, it delivers 1500 W peak pulse power (10/1000 µs waveform) with thermal resistance RθJA = 75 °C/W and RθJL = 15 °C/W, supporting reliable operation up to TJ = 150 °C.
Key Specifications

|---|---|
| VWM | 36 V - maximum continuous reverse stand-off voltage before clamping begins |
| PPPM | 1500 W - peak transient energy absorption capability under 10/1000 µs waveform |
| VC @ IPPM | 58.1 V - clamping voltage at 25.8 A peak pulse current, defining worst-case overvoltage seen by protected circuit |
| TJ max. | +150 °C - maximum operating junction temperature, enabling use in under-hood automotive environments |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) in engine control units exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed across differential signal pair or supply rail to limit transient overvoltage. Use Value: Clamps 1500 W surges to ≤58.1 V while maintaining <1 µA leakage at 36 V, preserving signal integrity and preventing latch-up in connected microcontrollers. | Use Scenario: Safeguarding digital input/output channels of programmable logic controllers against field-wiring induced transients and relay coil flyback. IC Role / Device Role / Timing Role: Parallel-connected transient suppressor on 24 V DC I/O lines to absorb inductive kickback without affecting steady-state operation. Use Value: Withstands 200 A uni-directional surge (IFSM) and maintains 36 V stand-off, enabling robust operation in factory automation environments with frequent switching noise. |
| Telecom Line Interface Protection | Consumer Power Adapter Surge Suppression |
Use Scenario: Shielding Ethernet PHY interfaces and RS-485 transceivers in network equipment from lightning-induced surges and ESD events. IC Role / Device Role / Timing Role: Bi-directional TVS placed between differential data lines and ground to shunt common-mode transients. Use Value: Symmetrical clamping ensures equal protection for both line polarities; 58.1 V VC limits stress on 3.3 V or 5 V PHY receivers during 10/1000 µs surges. | Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters and USB PD chargers subjected to mains-borne surges. IC Role / Device Role / Timing Role: Clamp across DC output rails (e.g., 5 V, 9 V, 12 V) to prevent damage to connected devices during surge events. Use Value: 36 V VWM matches typical 5 V–12 V adapter outputs; 1500 W PPPM handles IEC 61000-4-5 Level 3 surges without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/57T | Uni-directional; 36 V VWM, 400 W PPPM, SMA package | Limited to DC-biased circuits requiring polarity-aware protection | Select when lower cost and smaller footprint are prioritized over surge capacity and bi-directionality |
| SMCJ36CA-E3/57T | Bi-directional; 36 V VWM, 1500 W PPPM, DO-214AB package | Same electrical specs but larger DO-214AB footprint and higher RθJA (85 °C/W) | Choose if existing PCB layout uses DO-214AB or requires higher thermal mass for extended surge duty cycles |
Compared with SMAJ36A-E3/57T and SMCJ36CA-E3/57T, SMCG36-E3/57T offers identical 1500 W surge rating and AEC-Q101 qualification in a lower-profile DO-215AB package with superior thermal resistance (RθJA = 75 °C/W), making it optimal for space-constrained automotive and industrial modules where board height and thermal performance are critical.

FAQ
What is the clamping voltage of SMCG36-E3/57T at its rated peak pulse current?
The SMCG36-E3/57T clamps to a maximum of 58.1 V at its specified peak pulse current of 25.8 A under a 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and is measured per ANSI/IEEE C62.35 standards. The low clamping ratio (VC/VWM ≈ 1.61) reflects efficient energy diversion without excessive overvoltage stress on downstream components.
Is SMCG36-E3/57T suitable for automotive applications?
Yes, SMCG36-E3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its 150 °C maximum junction temperature, MSL Level 1 rating, and validation across temperature cycling, HTRB, and ESD tests confirm suitability for under-hood and cabin environments. The bi-directional configuration supports protection of differential buses like CAN and LIN without polarity constraints.
Does SMCG36-E3/57T require a heatsink for standard operation?
No, SMCG36-E3/57T is designed for operation without an external heatsink when mounted on the recommended 8.0 mm × 8.0 mm copper pads per terminal. Its thermal resistance RθJA = 75 °C/W and RθJL = 15 °C/W allow safe dissipation of its 6.5 W steady-state power rating (PD) at TA = 50 °C. Heatsinking is unnecessary for transient suppression duty, as energy is absorbed capacitively and dissipated over short durations.
How does the DO-215AB package of SMCG36-E3/57T compare to DO-214AB in size and thermal performance?
The DO-215AB (SMCG) package of SMCG36-E3/57T measures 7.87 mm × 10.16 mm with 1.90 mm height, making it lower profile than DO-214AB (SMC) at 7.11 mm × 10.29 mm × 2.62 mm. Thermally, SMCG36-E3/57T achieves RθJA = 75 °C/W versus ~85 °C/W for typical DO-214AB devices, due to optimized leadframe design and pad layout-enabling better power density and suitability for compact, thermally demanding layouts.
What is the reverse leakage current specification for SMCG36-E3/57T at its stand-off voltage?
At its 36 V stand-off voltage (VWM), SMCG36-E3/57T exhibits a maximum reverse leakage current (ID) of 1.0 µA at TA = 25 °C. This ultra-low leakage ensures minimal power loss and signal distortion in always-on circuits such as sensor bias networks or high-impedance communication lines, preserving battery life in portable and automotive systems where quiescent current is tightly constrained.
