Product details
Overview
SMCG9.0-E3/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) in DO-215AB (SMCG) package, designed for clamping voltage transients on signal and power lines. It features 9.0 V stand-off voltage (VWM), 15.4 V maximum clamping voltage (VC) at 97.4 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the SMCG9.0-E3/57T datasheet, SMCG9.0-E3/57T pinout, SMCG9.0-E3/57T application, or SMCG9.0-E3/57T equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, low incremental surge resistance, UL 94 V-0 molding compound, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCG9.0-E3/57T operates as a bi-directional avalanche diode with symmetrical breakdown characteristics in both polarities, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while the DO-215AB package provides low thermal resistance (RθJA = 75 °C/W) and meets MSL Level 1 reflow requirements (260 °C peak).
It delivers 1500 W peak pulse power handling per 10/1000 µs waveform under derated conditions above 25 °C ambient, with clamping voltage tightly controlled at ≤15.4 V up to 97.4 A - critical for safeguarding 3.3 V and 5 V logic interfaces against ESD and load-switching surges in automotive and industrial environments.
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 |
|---|---|---|---|
| SMAJ9.0A-E3/57T | Uni-directional; 9.0 V VWM, 14.4 V VC @ 75.4 A; SMA package (DO-214AC); lower PPPM (400 W). | Requires polarity-aware layout; unsuitable for AC or floating lines; limited to DC-biased signal protection. | Select only when unidirectional clamping suffices and board space permits larger SMA footprint. |
| SMCJ9.0CA | Bi-directional; same VWM/VC specs; DO-214AB (SMC) package; higher thermal mass but larger footprint (7.11 mm × 6.22 mm vs. SMCG's 4.06 mm × 3.30 mm). | Compatible functionally but occupies ~2.5× more PCB area; better for high-reliability industrial use where thermal margin > size constraint. | Prefer when higher surge repetition tolerance is needed and layout allows larger SMC package. |
