Product details
Overview
SMCJ130CAHE3_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 130 V standoff voltage (VWM), 209 V maximum clamping voltage (VC) at 7.2 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 SMCJ130CAHE3_A/H datasheet, SMCJ130CAHE3_A/H pinout, SMCJ130CAHE3_A/H application, or SMCJ130CAHE3_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
The SMCJ130CAHE3_A/H operates as a silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both polarities due to its bidirectional construction. Its breakdown voltage (VBR) ranges from 144 V to 159 V at 1 mA test current, with low incremental surge resistance enabling stable voltage limiting during fast transients.
Designed for high-energy surge immunity per IEC 61000-4-5 (indirect lightning), it sustains repetitive surges when derated above TA = 25 °C per Fig. 2, and meets J-STD-020 MSL level 1 with peak reflow temperature up to 260 °C - confirming suitability for lead-free assembly without moisture sensitivity concerns.
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 |
|---|---|---|---|
| SMBJ130CAHE3_A/H | Lower PPPM (600 W), smaller SMB (DO-214AA) package, same VWM and VC | Suitable only for lower-energy transients; limited thermal mass reduces surge repetition capability | Select when board space is constrained and surge threat level is Class II (IEC 61000-4-2) |
| SMCJ130AHE3_A/H | Unidirectional version; includes cathode band marking and forward voltage drop (VF = 3.5 V @ 100 A) | Requires polarity-aware layout; unsuitable for AC or floating lines without external rectification | Choose only for DC-only rails where reverse conduction must be blocked |
Compared with SMCJ130CAHE3_A/H, SMBJ130CAHE3_A/H trades surge capacity for footprint reduction, while SMCJ130AHE3_A/H sacrifices bidirectionality for unidirectional blocking - making SMCJ130CAHE3_A/H the optimal choice for polarity-agnostic, high-energy protection in automotive and industrial settings.

FAQ
What does the "CA" suffix indicate in SMCJ130CAHE3_A/H?
The "CA" suffix denotes a bidirectional configuration - meaning the SMCJ130CAHE3_A/H provides symmetrical clamping in both forward and reverse directions, with identical electrical characteristics (VBR, VC, IPPM) regardless of polarity. This eliminates the need for orientation-aware placement and supports protection of AC-coupled or floating circuits, unlike unidirectional variants such as SMCJ130AHE3_A/H.
Is SMCJ130CAHE3_A/H qualified for automotive applications?
Yes, SMCJ130CAHE3_A/H is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (UHAST). The "HE3" suffix confirms RoHS-compliant construction with AEC-Q101 qualification, making SMCJ130CAHE3_A/H suitable for under-hood and chassis-mounted automotive modules.
What is the maximum clamping voltage of SMCJ130CAHE3_A/H and under what test condition?
The maximum clamping voltage (VC) of SMCJ130CAHE3_A/H is 209 V, measured at a peak pulse current (IPPM) of 7.2 A using a 10/1000 μs double-exponential surge waveform. This value is guaranteed across the full operating temperature range (−55 °C to +150 °C) and defines the upper voltage limit imposed on protected circuitry during transient events.
How does the SMC (DO-214AB) package of SMCJ130CAHE3_A/H affect thermal performance?
The SMC (DO-214AB) package delivers RθJA = 75 °C/W and RθJL = 15 °C/W, enabling effective heat dissipation when mounted on 8.0 mm × 8.0 mm copper pads per terminal. This thermal design allows SMCJ130CAHE3_A/H to sustain repeated surges at elevated ambient temperatures - critical for engine control units and industrial drives where airflow is limited.
Can SMCJ130CAHE3_A/H replace SMCJ130AHE3_A/H in a design?
No - SMCJ130CAHE3_A/H cannot directly replace SMCJ130AHE3_A/H without layout review, because the former is bidirectional (no polarity marking) while the latter is unidirectional (cathode band marked) and exhibits forward conduction. Substitution requires verifying that reverse conduction is acceptable and that clamping symmetry meets system requirements; PCB traces and grounding may need adjustment.
