Product details
Overview
SMCG36A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in DO-215AB (SMCG) package, with 40.0 V to 44.2 V breakdown voltage (VBR), 36 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive electronics protection.
For engineers reviewing the SMCG36A-E3/57T datasheet, SMCG36A-E3/57T pinout, SMCG36A-E3/57T application, or SMCG36A-E3/57T equivalent, key selection criteria include clamping voltage (58.1 V at IPPM), low incremental surge resistance, bidirectional capability via CA-suffix variants, and compliance with UL 497B and JESD201 Class 2 whisker testing.
Technical Context
This device operates as a unidirectional TVS diode with glass-passivated junction, optimized for fast response (<1 ns) to ESD and lightning-induced transients. Its 1500 W PPPM rating sustains high-energy surges while maintaining clamping voltage ≤58.1 V at rated IPPM = 25.8 A under 10/1000 µs waveform.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads, it delivers thermal resistance of 75 °C/W (junction-to-ambient) and supports operating junction temperatures from –55 °C to +150 °C. The E3 suffix confirms RoHS-compliant, industrial-grade construction with matte tin-plated leads.

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 | DO-214AC (SMA) package; lower PPPM (400 W); higher RθJA (110 °C/W); same VWM/VC specs | Limited to lower-energy transients; unsuitable for ISO 7637-2 load dump or high-current EFT | Select when board space allows larger footprint and surge energy is <400 W |
| SMCJ36A-E3/57T | DO-214AB (SMC) package; identical PPPM (1500 W); same VBR/VC; 20% larger body and 0.5 mm taller | Compatible with same surge standards but requires revised PCB pad layout and stencil design | Choose when existing SMC footprint is standardized and DO-215AB rework is impractical |
Compared with SMAJ36A-E3/57T and SMCJ36A-E3/57T, the SMCG36A-E3/57T delivers equal 1500 W surge handling in a 25% smaller footprint than SMC and superior thermal performance versus SMA, making it optimal for space-constrained automotive and industrial modules requiring AEC-Q101 validation.

FAQ
What is the clamping voltage of SMCG36A-E3/57T at its rated peak pulse current?
The SMCG36A-E3/57T has a maximum clamping voltage (VC) of 58.1 V when subjected to its rated peak pulse current (IPPM) of 25.8 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCG36A-E3/57T maintains this clamping performance across its qualified operating temperature range.
Is SMCG36A-E3/57T suitable for automotive applications?
Yes, the SMCG36A-E3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its –55 °C to +150 °C operating junction temperature range, MSL Level 1 reflow compatibility, and UL 497B recognition support deployment in engine control units, body electronics, and ADAS sensor modules. The SMCG36A-E3/57T meets ISO 7637-2 load dump and IEC 61000-4-5 surge immunity requirements when applied per Vishay's recommended layout.
How does the SMCG36A-E3/57T differ from bidirectional variants like SMCG36CA?
The SMCG36A-E3/57T is unidirectional, with polarity indicated by a cathode band and designed to clamp only reverse-biased transients. In contrast, SMCG36CA provides symmetrical clamping in both directions and carries no polarity marking. Both share identical VWM (36 V), VBR, and PPPM (1500 W), but the SMCG36A-E3/57T is selected for DC power rail protection, whereas SMCG36CA suits AC-coupled or differential signal lines such as RS-485 or CAN FD.
What is the thermal resistance of SMCG36A-E3/57T, and how does it affect PCB layout?
The SMCG36A-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. To maintain TJ ≤150 °C under 6.5 W steady-state dissipation, designers must allocate sufficient copper area and consider airflow or heatsinking. Reducing pad size increases RθJA, risking thermal runaway during repeated surges. The SMCG36A-E3/57T datasheet specifies minimum pad dimensions to ensure rated performance.
Does SMCG36A-E3/57T require special handling for moisture sensitivity?
No - the SMCG36A-E3/57T is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and may be reflowed at peak temperatures up to 260 °C without pre-baking. This eliminates moisture-related popcorning risk and simplifies manufacturing for high-volume automotive and industrial production. The SMCG36A-E3/57T's epoxy molding compound and matte tin plating further enhance process robustness in standard SMT lines.
