Product details
Overview
SMCG36AHE3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for high-energy surge protection with 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and 25.8 A peak pulse current (IPPM). It protects MOSFETs, ICs, and sensor signal lines in automotive powertrain and industrial motor control systems.
For engineers reviewing the SMCG36AHE3/57T datasheet, SMCG36AHE3/57T pinout, SMCG36AHE3/57T application, or SMCG36AHE3/57T equivalent, key selection criteria include clamping voltage (VC = 58.1 V at IPPM), AEC-Q101 qualification, MSL Level 1 rating, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCG36AHE3/57T uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective suppression of 10/1000 μs waveform transients. Its unidirectional polarity features a cathode band marking and supports reverse-biased operation up to 36 V stand-off.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15 °C/W, with maximum junction temperature rated at +150 °C. It meets J-STD-020 MSL Level 1 and is qualified to AEC-Q101 for automotive under-hood applications.
Key Specifications

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 | Lower PPPM (400 W), SMA (DO-214AC) package, same VWM/VBR range | Not AEC-Q101 qualified; suitable for commercial-grade consumer or computing applications only | Select when cost sensitivity outweighs automotive qualification and 1500 W surge margin is unnecessary |
| SMCJ36AHE3/57T | Same 1500 W PPPM and AEC-Q101, but SMC (DO-214AB) package with higher RθJA (85 °C/W) | Less efficient thermal dissipation on identical PCB area; requires larger copper pour for equivalent TJ rise | Select only if legacy SMC footprint reuse is mandatory and thermal derating can be accommodated |
Compared with SMAJ36A-E3/57T and SMCJ36AHE3/57T, the SMCG36AHE3/57T delivers superior thermal performance (RθJA = 75 °C/W), smaller DO-215AB footprint, and guaranteed AEC-Q101 compliance-making it optimal for space-constrained, thermally demanding automotive and industrial designs requiring full 1500 W surge headroom.

FAQ
What is the clamping voltage of the SMCG36AHE3/57T and how is it measured?
The SMCG36AHE3/57T has a maximum clamping voltage (VC) of 58.1 V, measured at its rated peak pulse current (IPPM = 25.8 A) using a standardized 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is verified per ANSI/IEEE C62.35 test conditions with the device mounted on 8.0 mm × 8.0 mm copper pads.
Is the SMCG36AHE3/57T suitable for automotive applications?
Yes, the SMCG36AHE3/57T is AEC-Q101 qualified and specifically designed for automotive use, including engine control units and onboard chargers. Its construction-glass-passivated junction, MSL Level 1 rating, and operation up to +150 °C junction temperature-meets stringent automotive reliability requirements outlined in the qualification standard.
What does the 'HE3' suffix indicate in SMCG36AHE3/57T?
The 'HE3' suffix denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads. 'H' indicates AEC-Q101 qualification, 'E3' specifies RoHS compliance and industrial-grade reliability, distinguishing it from non-automotive variants like 'E3' (industrial only) or 'HM3' (halogen-free + AEC-Q101).
How does the SMCG36AHE3/57T compare to SMAJ36A in terms of surge handling?
The SMCG36AHE3/57T provides 1500 W peak pulse power (PPPM), triple the 400 W rating of SMAJ36A-E3/57T. This enables robust protection against severe transients such as ISO 7637-2 Pulse 5a (load dump) or IEC 61000-4-5 Combination Wave, where SMAJ36A would fail or degrade prematurely under repeated stress.
What is the recommended PCB layout for optimal thermal performance of SMCG36AHE3/57T?
Vishay specifies mounting the SMCG36AHE3/57T on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal to achieve the published RθJA of 75 °C/W. Use internal copper planes and thermal vias beneath pads to enhance heat spreading; avoid narrow traces or isolation gaps that impede conduction from the SMCG36AHE3/57T leads to bulk copper.
