Product details
Overview
SMCJ160A-E3/9AT from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, with 160 V stand-off voltage (VWM), 259 V maximum clamping voltage (VC) at 5.8 A peak pulse current, and 1500 W peak pulse power rating for 10/1000 µs waveform. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in automotive power systems.
For engineers reviewing the SMCJ160A-E3/9AT datasheet, SMCJ160A-E3/9AT pinout, SMCJ160A-E3/9AT application, or SMCJ160A-E3/9AT equivalent, key selection criteria include unidirectional polarity, 178–197 V breakdown voltage range (VBR), 1.0 µA max reverse leakage at VWM, -55 °C to +150 °C operating junction temperature, and RoHS-compliant matte tin-plated leads solderable per J-STD-002.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (VBR = 178–197 V), limiting transient energy by diverting surge current away from protected circuitry. Its low incremental surge resistance and fast response time ensure effective suppression of sub-microsecond transients.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it delivers 1500 W peak pulse power dissipation under standardized 10/1000 µs waveform conditions and maintains stable clamping performance across -55 °C to +150 °C junction temperature range with 0.108 %/°C VBR temperature coefficient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A-E3/52T | Lower PPPM (600 W), smaller SMB (DO-214AA) package, same VWM/VC ratings | Reduced surge handling; suitable only for lower-energy transients or space-constrained designs | Select when board area is critical and surge threat level is limited to IEC 61000-4-2 Level 3 (8 kV contact) |
| SMCJ160CA-E3/9AT | Bidirectional variant with identical VWM, VBR, and VC; no polarity marking | Required for AC-coupled or floating signal lines where voltage polarity reversal occurs | Choose for RS-485, CAN bus, or audio line protection where bidirectional clamping is mandatory |
Compared with SMCJ160A-E3/9AT, SMBJ160A-E3/52T trades surge capacity for compactness, while SMCJ160CA-E3/9AT adds polarity symmetry at no clamping performance cost-enabling direct use in AC signal paths without redesign.

FAQ
What is the breakdown voltage range of the SMCJ160A-E3/9AT?
The SMCJ160A-E3/9AT has a guaranteed breakdown voltage (VBR) range of 178 V to 197 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This range ensures reliable turn-on behavior across manufacturing lots and temperature extremes, and is confirmed in Vishay's official datasheet revision 09-Jan-2024 (Document Number: 88394). The SMCJ160A-E3/9AT maintains this specification under standard test conditions and derates predictably above 25 °C ambient.
Is the SMCJ160A-E3/9AT RoHS-compliant and lead-free?
Yes, the SMCJ160A-E3/9AT is RoHS-compliant and lead-free, as indicated by the "E3" suffix in its ordering code. It features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards, and passes JESD 201 Class 2 whisker testing. The device meets UL 94 V-0 flammability requirements and carries no halogen restrictions-making it suitable for commercial and industrial applications where environmental compliance is mandatory. The SMCJ160A-E3/9AT documentation explicitly confirms this status in the Mechanical Data section.
What is the maximum clamping voltage of the SMCJ160A-E3/9AT under surge conditions?
The SMCJ160A-E3/9AT exhibits a maximum clamping voltage (VC) of 259 V at its rated peak pulse current (IPPM) of 5.8 A, tested with a 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is validated under standardized mounting conditions (0.31" × 0.31" copper pads). The SMCJ160A-E3/9AT achieves this performance with low incremental surge resistance, ensuring predictable protection margins for downstream 300 V-rated components.
Can the SMCJ160A-E3/9AT be used in automotive applications?
The SMCJ160A-E3/9AT itself is commercial-grade; however, Vishay offers AEC-Q101 qualified versions under ordering codes such as SMCJ160AHE3_A/I (HE3 suffix). While the SMCJ160A-E3/9AT shares identical electrical and thermal specifications-including -55 °C to +150 °C operating range and glass passivated junction-it lacks formal automotive qualification documentation. For production automotive use, engineers should specify the HE3 or HM3 variant. The SMCJ160A-E3/9AT remains suitable for prototyping and non-safety-critical automotive subsystems where qualification is not mandated.
What is the thermal resistance of the SMCJ160A-E3/9AT from junction to ambient?
The SMCJ160A-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the minimum recommended pad layout (0.31" × 0.31" copper pads per terminal). This value assumes still air conditions and is critical for estimating junction temperature rise under continuous power dissipation (PD = 6.5 W at TA = 50 °C). The SMCJ160A-E3/9AT also features RθJL = 15 °C/W (junction-to-lead), supporting thermal analysis in thermally constrained layouts. These parameters are published in the Thermal Characteristics table of the official Vishay datasheet.
