Product details
Overview
SMCJ160CAHE3_A/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of sensitive electronics. 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 10/1000 μs waveform - deployed in automotive power line and industrial sensor interface protection.
For engineers reviewing the SMCJ160CAHE3_A/H datasheet, SMCJ160CAHE3_A/H pinout, SMCJ160CAHE3_A/H application, or SMCJ160CAHE3_A/H equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within picoseconds to transients induced by inductive load switching or ESD events. Its bidirectional architecture ensures symmetrical clamping in both polarities, with breakdown voltage (VBR) specified between 178 V (min) and 197 V (max) at 1 mA test current - meeting ANSI/IEEE C62.35 standards for surge suppression.
Thermally, it sustains junction temperatures from −55 °C to +150 °C and delivers 6.5 W steady-state power dissipation on infinite heatsink at TA = 50 °C. The device uses glass-passivated silicon junctions and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min/max) | 178 V / 197 V at IT = 1 mA - defines reliable breakdown threshold under standardized test conditions |
| VC @ IPPM | 259 V at 5.8 A - clamping voltage during 10/1000 μs surge, limiting downstream voltage stress |
| PPPM | 1500 W - peak transient energy handling capacity per single 10/1000 μs pulse |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, critical for PCB pad layout design |
| TJ max. | +150 °C - maximum allowable junction temperature, enabling operation in under-hood automotive environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile case with molded UL 94 V-0 compound and matte tin-plated leads. Polarity marking: none for bidirectional types.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC160CA | Lower PPPM (600 W), same VWM (160 V), smaller SMA package (DO-214AC) | Limited to lower-energy transients; unsuitable for ISO 16750-2 load dump | Select when board space is constrained and surge energy remains below 600 W |
| SMCJ160AHE3_A/H | Unidirectional version; identical VWM, VC, and PPPM but asymmetric clamping (cathode-banded) | Requires polarity-aware placement; not usable on AC or floating lines | Choose only for DC-biased rails where reverse conduction must be blocked |
Compared with SAC160CA and SMCJ160AHE3_A/H, the SMCJ160CAHE3_A/H uniquely combines 1500 W surge capacity, bidirectional symmetry, and AEC-Q101 qualification - making it the only option qualified for automotive power line protection where polarity independence and high-energy immunity are mandatory.

FAQ
What is the clamping voltage of SMCJ160CAHE3_A/H at its rated peak pulse current?
The SMCJ160CAHE3_A/H has a maximum clamping voltage (VC) of 259 V when subjected to its rated peak pulse current (IPPM) of 5.8 A under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable voltage limiting during surge events - critical for protecting downstream 300 V-rated components. The SMCJ160CAHE3_A/H maintains this clamping performance across its full operating temperature range (−55 °C to +150 °C).
Is SMCJ160CAHE3_A/H suitable for automotive applications?
Yes, the SMCJ160CAHE3_A/H is AEC-Q101 qualified and explicitly designed for automotive use, including engine control units, body electronics, and ADAS power domains. Its qualification covers temperature cycling, highly accelerated life testing (HALT), and ESD robustness per automotive stress profiles. The SMCJ160CAHE3_A/H also meets MSL Level 1 for lead-free reflow, supporting high-reliability manufacturing in Tier 1 automotive supply chains.
How does the bidirectional configuration of SMCJ160CAHE3_A/H affect circuit layout?
The bidirectional configuration of SMCJ160CAHE3_A/H eliminates polarity sensitivity - no cathode band marking is present, and either terminal may connect to either side of a differential or AC-coupled line. This simplifies PCB layout by removing orientation constraints and enables symmetric placement on balanced interfaces like RS-485 or CAN bus power rails. The SMCJ160CAHE3_A/H requires only two 8.0 mm × 8.0 mm copper pads per terminal for optimal thermal and surge performance.
What is the standoff voltage rating of SMCJ160CAHE3_A/H, and how does it relate to system operating voltage?
The SMCJ160CAHE3_A/H has a standoff voltage (VWM) of 160 V - the maximum continuous DC or RMS voltage it can withstand without entering avalanche conduction. For reliable operation, system nominal voltage must remain ≤80 % of VWM (i.e., ≤128 V for 160 V VWM) to accommodate tolerance, ripple, and transients. This makes the SMCJ160CAHE3_A/H ideal for 100 V–120 V DC systems such as 48 V PoE++ infrastructure or dual-battery industrial platforms.
Does SMCJ160CAHE3_A/H require derating at elevated ambient temperatures?
Yes, the SMCJ160CAHE3_A/H requires thermal derating above TA = 25 °C, as shown in Figure 2 of its datasheet (Document Number: 88394). At TA = 85 °C, its peak pulse power capability drops to approximately 750 W - 50 % of the 1500 W rating at 25 °C. Derating is governed by junction-to-ambient thermal resistance (RθJA = 75 °C/W); proper copper pad sizing (minimum 8.0 mm × 8.0 mm per terminal) is essential to maintain performance. The SMCJ160CAHE3_A/H's TJ max. of +150 °C sets the absolute upper limit for sustained operation.
