Product details
Overview
SMCJ160A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 160 V standoff voltage (VWM), 259 V maximum clamping voltage (VC) at 5.8 A peak pulse current (IPPM), and 1500 W peak pulse power dissipation (PPPM) with a 10/1000 μs waveform - deployed in automotive power supplies, industrial motor controllers, and telecom DC input stages.
For engineers reviewing the SMCJ160A-E3/57T datasheet, SMCJ160A-E3/57T pinout, SMCJ160A-E3/57T application, or SMCJ160A-E3/57T equivalent, key selection criteria include verified clamping performance under 10/1000 μs transients, unidirectional polarity marking, SMC (DO-214AB) package thermal resistance (RθJA = 75 °C/W), and AEC-Q101 qualification eligibility via HE3 suffix variants.
Technical Context
The SMCJ160A-E3/57T operates as a silicon avalanche diode, triggering conduction when reverse voltage exceeds its breakdown range (178–197 V at 1 mA test current). Its low incremental surge resistance and fast response time (<1 ns) enable effective suppression of ESD, lightning-induced surges, and inductive switching transients.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it delivers stable clamping up to TJ = 150 °C and meets J-STD-020 MSL Level 1 (peak reflow 260 °C), with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/61 | Lower PPPM (400 W), SMA package (DO-214AC), higher RθJA (110 °C/W) | Suitable only for lower-energy transients; not recommended for ISO 7637-2 Pulse 5a | Select when board space is constrained and surge threat level is limited to IEC 61000-4-2 ESD only |
| SMCJ160CA-E3/57T | Bidirectional variant; identical VWM (160 V), VC (259 V), and PPPM (1500 W); no polarity marking | Required for AC-coupled or floating signal lines where voltage reversal occurs | Choose for RS-485 data lines or transformer-isolated DC/DC feedback paths needing symmetrical clamping |
Compared with SMAJ160A-E3/61 and SMCJ160CA-E3/57T, the SMCJ160A-E3/57T provides optimal balance of high-power surge handling, thermal performance, and unidirectional polarity control for DC power rail protection - making it preferred for automotive and industrial 160 V nominal systems where directional clamping and PCB thermal management are critical.

FAQ
What is the breakdown voltage range of the SMCJ160A-E3/57T?
The SMCJ160A-E3/57T has a guaranteed breakdown voltage (VBR) range of 178 V to 197 V at a test current of 1 mA, measured per ANSI/IEEE C62.35 standards. This range ensures consistent avalanche initiation across production lots and supports robust design margins against overvoltage events. The SMCJ160A-E3/57T maintains this specification under TA = 25 °C conditions with proper PCB thermal relief.
Is the SMCJ160A-E3/57T suitable for automotive applications?
The SMCJ160A-E3/57T itself is commercial-grade (E3 suffix), but Vishay offers AEC-Q101 qualified versions under HE3/HM3 suffixes (e.g., SMCJ160AHE3_A/H). These variants undergo stress testing per automotive reliability standards and are approved for use in engine control units, body electronics, and ADAS power modules. The SMCJ160A-E3/57T serves as the baseline design reference for those qualified derivatives.
What is the maximum clamping voltage of the SMCJ160A-E3/57T under surge conditions?
The SMCJ160A-E3/57T exhibits a maximum clamping voltage (VC) of 259 V when subjected to its rated peak pulse current of 5.8 A using the standardized 10/1000 μs double-exponential waveform. This value is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per terminal and defines the upper voltage limit imposed on protected circuitry during worst-case transients. The SMCJ160A-E3/57T achieves this performance with minimal overshoot due to its low incremental surge resistance.
Does the SMCJ160A-E3/57T have a bidirectional counterpart?
Yes - the SMCJ160CA-E3/57T is the bidirectional variant of the SMCJ160A-E3/57T, sharing identical electrical ratings including VWM (160 V), VC (259 V), and PPPM (1500 W), but with symmetrical breakdown in both directions and no polarity marking. Unlike the SMCJ160A-E3/57T, which uses a banded cathode for unidirectional operation, the SMCJ160CA-E3/57T is used where voltage polarity reversal occurs, such as in AC signal lines or isolated feedback paths.
What package type does the SMCJ160A-E3/57T use and what are its mounting requirements?
The SMCJ160A-E3/57T uses the SMC (DO-214AB) surface-mount package, measuring 7.75 mm × 6.22 mm × 2.62 mm with a 3.20 mm minimum standoff height. It requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal for thermal and surge-current handling per Vishay's datasheet recommendations. The SMCJ160A-E3/57T is compatible with standard lead-free reflow profiles and meets J-STD-020 MSL Level 1.
