Product details
Overview
SMCJ160AHE3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 160 V standoff voltage (VWM), 178–197 V breakdown voltage (VBR), and 259 V clamping voltage (VC) at 5.8 A peak pulse current (IPPM). It delivers 1500 W peak pulse power (10/1000 µs waveform) and is AEC-Q101 qualified for automotive electronics.
For engineers reviewing the SMCJ160AHE3/57T datasheet, SMCJ160AHE3/57T pinout, SMCJ160AHE3/57T application, or SMCJ160AHE3/57T equivalent, key selection criteria include clamping performance under 10/1000 µs transients, junction temperature derating above 25 °C, unidirectional polarity marking, and compliance with UL 497B and AEC-Q101 for harsh-environment deployment.
Technical Context
The SMCJ160AHE3/57T uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients. Its unidirectional configuration provides cathode-band polarity identification and supports DC-biased signal or power line protection.
Thermal design relies on RθJA = 75 °C/W (junction-to-ambient, on recommended 8.0 mm × 8.0 mm copper pads) and RθJL = 15 °C/W (junction-to-lead), supporting operation from –55 °C to +150 °C. The device meets MSL Level 1 per J-STD-020 and is rated for 200 A non-repetitive forward surge (8.3 ms half-sine).
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 |
|---|---|---|---|
| SMAJ160A-E3/61 | Lower PPPM (400 W), SMA package (smaller thermal mass), higher RθJA (~150 °C/W). | Suitable only for lower-energy transients; not AEC-Q101 qualified; limited to commercial temperature range. | Select when board space is constrained and surge threat level is ≤ IEC 61000-4-5 Level 3. |
| 1.5KE160A | Through-hole DO-201 package, same VWM/VBR/VC specs, but larger footprint and manual assembly requirement. | Preferred in legacy industrial designs where reworkability and high-surge margin outweigh SMT density needs. | Choose when field serviceability or compatibility with existing through-hole layouts is mandatory. |
Compared with SMCJ160AHE3/57T, SMAJ160A-E3/61 trades surge capacity and automotive qualification for compact size, while 1.5KE160A retains identical electrical performance but requires through-hole assembly and lacks AEC-Q101 validation.

FAQ
What is the clamping voltage of the SMCJ160AHE3/57T under a 10/1000 µs surge?
The SMCJ160AHE3/57T clamps to a maximum of 259 V when subjected to its rated peak pulse current of 5.8 A using the standard 10/1000 µs waveform. This value is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per Vishay's test condition, and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the SMCJ160AHE3/57T suitable for automotive applications?
Yes, the SMCJ160AHE3/57T is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix. It has passed stress tests including temperature cycling, high-temperature operating life, and mechanical shock, making it appropriate for engine control units, body electronics, and ADAS power supplies where reliability under harsh conditions is mandatory.
How does the SMCJ160AHE3/57T differ from bidirectional variants like SMCJ160CA?
The SMCJ160AHE3/57T is unidirectional and features a cathode band for polarity identification, allowing it to protect DC-biased lines such as power rails. In contrast, SMCJ160CA is bidirectional with no polarity marking and is intended for AC or symmetrical signal lines. Their VBR, VWM, and VC values differ accordingly-SMCJ160AHE3/57T has VWM = 160 V and VBR = 178–197 V, while SMCJ160CA has VWM = 160 V but symmetric breakdown in both directions.
What is the thermal resistance of the SMCJ160AHE3/57T, and how does it affect PCB layout?
The SMCJ160AHE3/57T 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 maintain TJ ≤ 150 °C under full 1500 W surge duty, designers must ensure adequate copper area and avoid excessive ambient temperature buildup-undersized pads increase RθJA and risk thermal runaway during repeated surges.
Does the SMCJ160AHE3/57T meet any safety certifications?
Yes, the SMCJ160AHE3/57T carries Underwriters Laboratories (UL) recognition under file number E136766 for both unidirectional and bidirectional configurations, compliant with UL 497B for signal and power line protectors. It also meets RoHS and halogen-free requirements per Vishay's HE3 designation, and is rated for flammability UL 94 V-0 in its molding compound.
