Product details
Overview
SMCG160A-E3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) surface-mount package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 160 V stand-off voltage (VWM), 178–197 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), 5.8 A maximum clamping current (IPPM), and clamps to 259 V at rated surge. It is AEC-Q101 qualified and used in automotive power supply input stages.
For engineers reviewing the SMCG160A-E3/57T datasheet, SMCG160A-E3/57T pinout, SMCG160A-E3/57T application, or SMCG160A-E3/57T equivalent, key selection criteria include unidirectional polarity, DO-215AB thermal performance (RθJA = 75 °C/W), 1500 W surge rating, AEC-Q101 qualification, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, entering avalanche conduction when reverse voltage exceeds VBR (178–197 V). Its low incremental surge resistance and fast response time (<1 ns) enable effective suppression of ESD, lightning-induced transients, and inductive switching spikes.
The SMCG160A-E3/57T uses a glass-passivated silicon junction housed in an MSL Level 1, RoHS-compliant SMCG package with matte tin-plated leads. It supports unidirectional operation only (cathode marked), has a maximum junction temperature of +150 °C, and is rated for 200 A non-repetitive forward surge (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail protection threshold. |
| VBR (min/max) | 178 V / 197 V at 1 mA - Confirmed breakdown range ensures reliable turn-on margin above VWM for stable clamping behavior. |
| VC @ IPPM | 259 V at 5.8 A - Clamping voltage under full 1500 W surge (10/1000 µs); determines maximum stress imposed on downstream ICs. |
| PPPM | 1500 W - Peak pulse power handling capability; enables protection against high-energy transients per IEC 61000-4-5 Level 4. |
| ID @ VWM | 1.0 µA - Ultra-low reverse leakage at stand-off voltage; minimizes standby power loss in battery-powered systems. |
| TJ max. | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive environments. |
| RθJA | 75 °C/W - Thermal resistance from junction to ambient on standard 8.0 mm × 8.0 mm pads; informs heatsinking requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/57T | Same VWM (160 V) and PPPM (400 W), but lower power rating and SMA (DO-214AC) package with higher RθJA (100 °C/W). | Limited to lower-energy transients; unsuitable for ISO 16750-2 load dump without parallel staging. | Select when cost sensitivity outweighs surge margin and board space allows larger thermal pad area. |
| SMCJ160A-E3/57T | Same VWM (160 V) and higher PPPM (1500 W), but SMC (DO-214AB) package with identical RθJA (75 °C/W) and AEC-Q101 qualification. | Compatible with same PCB layout if footprint adapted; offers identical electrical performance in larger body. | Choose when mechanical robustness or legacy SMC footprint compatibility is prioritized over low-profile height constraint. |
Compared with SMCG160A-E3/57T, SMAJ160A-E3/57T provides reduced surge capacity in a smaller package, while SMCJ160A-E3/57T delivers identical clamping and power specs in a physically larger but mechanically more rugged SMC outline - enabling direct functional substitution where height clearance permits.

FAQ
What is the polarity configuration of the SMCG160A-E3/57T?
The SMCG160A-E3/57T is a unidirectional transient voltage suppressor diode. Its cathode is marked with a band on the SMCG (DO-215AB) package body, and it conducts surge current only when the cathode is at a higher potential than the anode. This configuration makes it suitable for DC rail protection where polarity is fixed, unlike bidirectional variants such as SMCG160CA.
Does the SMCG160A-E3/57T meet automotive qualification standards?
Yes, the SMCG160A-E3/57T is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per JESD22-A114. This certification confirms its suitability for use in automotive electronic control units, body electronics, and powertrain subsystems operating across -55 °C to +150 °C.
What is the maximum clamping voltage of the SMCG160A-E3/57T under surge conditions?
The SMCG160A-E3/57T clamps to a maximum of 259 V when subjected to its rated peak pulse current of 5.8 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 standardized surge events.
How does the SMCG160A-E3/57T perform thermally on a standard PCB layout?
When mounted on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, the SMCG160A-E3/57T exhibits a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W. This enables sustained 6.5 W power dissipation at TA = 50 °C and supports reliable operation in compact, high-density automotive PCBs without additional heatsinking.
Is the SMCG160A-E3/57T compatible with lead-free reflow processes?
Yes, the SMCG160A-E3/57T carries the "E3" suffix indicating RoHS compliance and qualification for lead-free reflow with a maximum peak temperature of 260 °C (MSL Level 1 per J-STD-020). Its matte tin-plated leads meet J-STD-002 solderability requirements, supporting high-yield automated assembly without pre-baking.
