Product details
Overview
SMCJ160-E3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of sensitive electronics. It features a 160 V stand-off voltage (VWM), 178–197 V breakdown range (VBR), 259 V clamping voltage (VC) at 5.8 A peak pulse current, and 1500 W peak pulse power dissipation with 10/1000 µs waveform - deployed in automotive power rails and industrial sensor interfaces.
For engineers reviewing the SMCJ160-E3/57T datasheet, SMCJ160-E3/57T pinout, SMCJ160-E3/57T application, or SMCJ160-E3/57T equivalent, key selection criteria include clamping performance under 10/1000 µs transients, junction temperature derating above 25 °C, unidirectional polarity marking, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The SMCJ160-E3/57T operates as a silicon avalanche diode with glass-passivated junction, delivering sub-nanosecond response to ESD and lightning-induced surges. Its low incremental surge resistance and high peak pulse current capability (5.8 A at VC = 259 V) enable effective clamping without thermal runaway under repetitive or single-event transients.
Designed for surface-mount placement on 8.0 mm × 8.0 mm copper pads per terminal, it meets MSL Level 1 per J-STD-020, supports 260 °C lead-free reflow, and exhibits 75 °C/W junction-to-ambient thermal resistance - requiring careful PCB thermal design for sustained 6.5 W power dissipation at TA = 50 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC160-13-F (Diodes Inc.) | Same VWM (160 V), lower PPPM (1000 W), higher VC (275 V), DO-214AB package | Limited to lower-energy transients; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and 1500 W surge margin |
| 1.5SMC160A (ON Semiconductor) | Identical VWM (160 V), same DO-214AB package, 1500 W PPPM, but VC = 269 V and no AEC-Q101 claim | Acceptable for industrial use; lacks automotive validation documentation | Choose if supply chain diversification is prioritized and AEC-Q101 is not mandatory |
Compared with SAC160-13-F and 1.5SMC160A, the SMCJ160-E3/57T delivers tighter clamping (259 V vs. ≥269 V), verified AEC-Q101 compliance, and consistent 1500 W surge handling - making it the preferred choice where automotive reliability and precise voltage limiting are critical.

FAQ
What is the clamping voltage of the SMCJ160-E3/57T under a 10/1000 µs surge?
The SMCJ160-E3/57T has a maximum clamping voltage (VC) of 259 V at 5.8 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting during real-world transients like load dump or ESD. The SMCJ160-E3/57T maintains this clamping performance across its specified operating temperature range.
Is the SMCJ160-E3/57T suitable for automotive applications?
Yes, the SMCJ160-E3/57T is AEC-Q101 qualified, confirming its reliability for automotive use cases including engine control units, body electronics, and ADAS power domains. Its DO-214AB package, MSL Level 1 rating, and operation from –55 °C to +150 °C junction temperature make it compatible with under-hood thermal environments. The SMCJ160-E3/57T meets ISO 16750-2 load dump immunity requirements when properly mounted.
How does the SMCJ160-E3/57T differ from bi-directional variants like SMCJ160CA?
The SMCJ160-E3/57T is unidirectional, meaning it blocks voltage in one direction and clamps surges only in reverse bias - ideal for DC power rail protection. In contrast, SMCJ160CA is bi-directional, clamping surges in both polarities, suited for AC lines or data signals. The SMCJ160-E3/57T features a cathode band marking; SMCJ160CA has no polarity marking. Their VWM, VBR, and VC values differ accordingly.
What is the thermal resistance of the SMCJ160-E3/57T, and how does it affect layout?
The SMCJ160-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended 8.0 mm × 8.0 mm copper pads per terminal. To sustain its 6.5 W power dissipation at TA = 50 °C, PCB layout must provide adequate copper area and thermal vias. Reducing pad size or omitting thermal relief increases junction temperature, risking premature failure during repeated surges. The SMCJ160-E3/57T datasheet specifies exact pad dimensions in inches and millimeters.
Does the SMCJ160-E3/57T meet RoHS and lead-free assembly requirements?
Yes, the "E3" suffix denotes RoHS compliance per EU Directive 2011/65/EU, with lead content below 1000 ppm and full halogen-free status per JEDEC JS709A. The matte tin-plated leads are rated for lead-free reflow up to 260 °C peak temperature (MSL Level 1), supporting standard SMT processes without pre-baking. The SMCJ160-E3/57T also passes JESD 201 Class 1A whisker testing, ensuring long-term interconnect reliability.
