Product details
Overview
SMCG58A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) in DO-215AB (SMCG) package, with 58 V standoff voltage (VWM), 64.4–71.2 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and 16.0 A peak pulse current (IPPM) at 10/1000 µs waveform. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in automotive and industrial power electronics.
For engineers reviewing the SMCG58A-E3/57T datasheet, SMCG58A-E3/57T pinout, SMCG58A-E3/57T application, or SMCG58A-E3/57T equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, clamping behavior under surge, thermal resistance (RθJA = 75 °C/W), and direct replacement guidance for circuit protection design.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device: when reverse voltage exceeds VBR (64.4–71.2 V), it avalanches to limit transient voltage across protected circuitry. Its glass-passivated junction ensures stable breakdown and low leakage (≤1.0 µA at VWM).
Designed for 10/1000 µs surge waveforms per ANSI/IEEE C62.35, it delivers 93 V clamping voltage (VC) at IPPM and sustains 200 A non-repetitive forward surge (IFSM). Thermal performance is defined by RθJA = 75 °C/W on 8.0 mm × 8.0 mm copper pads, with operating junction temperature up to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VWM | 58 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 64.4 V / 71.2 V - guaranteed avalanche initiation range at 1 mA test current |
| VC @ IPPM | 93 V - clamped voltage during 16.0 A 10/1000 µs surge, defining protection window |
| PPPM | 1500 W - peak transient energy handling capacity under standardized waveform |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ58A-E3/57T | DO-214AC (SMA) package; lower PPPM (400 W); higher RθJA (110 °C/W) | Limited to lower-energy transients; unsuitable for automotive load dump per ISO 7637-2 Pulse 5a | Select only for space-constrained consumer designs where 1500 W rating is not required |
| SMCJ58A-E3/57T | DO-214AB (SMC) package; same 1500 W PPPM but larger footprint (7.11 mm × 6.22 mm vs. 6.60 mm × 5.59 mm) | Compatible with higher thermal mass layouts; requires PCB area increase of ~35% | Choose when board layout allows larger pad area and enhanced long-duration surge margin is needed |
Compared with SMAJ58A-E3/57T and SMCJ58A-E3/57T, SMCG58A-E3/57T uniquely balances AEC-Q101 compliance, compact DO-215AB footprint, and full 1500 W surge capability-making it optimal for high-density automotive control modules where thermal and space constraints coexist.

FAQ
What is the clamping voltage of SMCG58A-E3/57T at its rated peak pulse current?
The SMCG58A-E3/57T has a maximum clamping voltage (VC) of 93 V at its specified peak pulse current (IPPM) of 16.0 A under a 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 93 V VC ensures compatibility with 100 V-rated downstream components while maintaining safe margin below typical 120 V transient thresholds in automotive applications.
Is SMCG58A-E3/57T qualified for automotive use?
Yes, SMCG58A-E3/57T is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensors. The qualification covers stress tests such as high-temperature reverse bias, temperature cycling, and accelerated life testing. Its DO-215AB package meets MSL Level 1 and supports lead-free reflow up to 260 °C, aligning with automotive manufacturing standards.
How does the SMCG58A-E3/57T differ from the SMAJ58A-E3/57T in terms of surge handling?
SMCG58A-E3/57T delivers 1500 W peak pulse power (PPPM) versus 400 W for SMAJ58A-E3/57T, enabling it to absorb three times more transient energy. Its lower thermal resistance (RθJA = 75 °C/W vs. 110 °C/W) improves sustained surge performance, and its DO-215AB package supports higher IFSM (200 A vs. 40 A). These differences make SMCG58A-E3/57T appropriate for ISO 7637-2 Pulse 5a load dump protection where SMAJ58A-E3/57T would fail.
What is the reverse leakage current specification for SMCG58A-E3/57T at its standoff voltage?
At its 58 V standoff voltage (VWM), the SMCG58A-E3/57T exhibits a maximum reverse leakage current (ID) of 1.0 µA at TA = 25 °C. This ultra-low leakage minimizes standby power loss in always-on automotive modules and preserves accuracy in precision sensor bias networks. The value is confirmed per the Vishay datasheet (Document Number: 88457) and applies to all units within the specified operating temperature range.
Can SMCG58A-E3/57T be used in bidirectional configurations?
No, SMCG58A-E3/57T is a unidirectional TVS diode, identifiable by the cathode band marking. Bidirectional operation requires the CA-suffixed variant (e.g., SMCG58CA). Using SMCG58A-E3/57T in reverse-biased signal lines without polarity awareness risks forward conduction and failure. For AC-coupled or differential signal protection, select the explicitly rated bidirectional version from the same SMCG family.
