Product details
Overview
SMCJ10CAHE3/57T 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 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage (VC) at 88.2 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMCJ10CAHE3/57T datasheet, SMCJ10CAHE3/57T pinout, SMCJ10CAHE3/57T application, or SMCJ10CAHE3/57T equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, low thermal resistance (RθJL = 15 °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: under normal conditions it presents high impedance (>1 MΩ leakage at VWM), then rapidly avalanches to limit transient voltages across protected nodes. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance.
The bidirectional configuration enables symmetric suppression of both positive and negative transients without polarity sensitivity - critical for AC-coupled signal lines and floating bus interfaces. It meets J-STD-020 MSL Level 1 and supports peak surge currents up to 200 A (IFSM) in unidirectional mode, though SMCJ10CAHE3/57T is rated for bidirectional use only.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before clamping initiates; defines safe working range for protected circuitry. |
| VBR min/max | 11.1 V / 12.3 V at IT = 1.0 mA - verified breakdown threshold ensuring predictable turn-on during transients. |
| VC @ IPPM | 17.0 V at 88.2 A (10/1000 µs) - clamping voltage limits stress on downstream ICs such as CAN transceivers or microcontrollers. |
| PPPM | 1500 W - peak transient energy handling capacity, enabling protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surges. |
| ID @ VWM | 5.0 µA - ultra-low reverse leakage preserves signal integrity and minimizes standby power loss in battery-powered systems. |
| TJ max | +150 °C - extended junction temperature rating supports operation in under-hood automotive environments. |
| RθJL | 15 °C/W - low junction-to-lead thermal resistance enables efficient heat transfer to PCB copper, sustaining repetitive surge capability. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional - no polarity marking; symmetrical two-terminal construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Common terminal pair | Both terminals function identically; voltage clamping occurs symmetrically across the device regardless of transient polarity. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC10CA | Same VWM (10 V) and bidirectional configuration, but lower PPPM (600 W); smaller SMA package (DO-214AC). | Limited to lower-energy transients (e.g., ESD-only); unsuitable for ISO 7637-2 load dump. | Select when board space is constrained and surge requirements are limited to IEC 61000-4-2/4-4. |
| SMCJ10CAHM3/57T | Identical electrical specs and AEC-Q101 qualification; differs only in halogen-free molding compound (HM3 vs HE3). | No functional difference; chosen solely to meet RoHS + halogen-free compliance mandates (e.g., EU ELV Directive). | Use when environmental compliance requires halogen-free materials - otherwise HE3 is fully interchangeable. |
Compared with SAC10CA, SMCJ10CAHE3/57T delivers 2.5× higher surge power handling and superior thermal performance via larger SMC package; versus SMCJ10CAHM3/57T, it offers identical protection capability with standard RoHS-compliant materials - making HE3 the default choice unless halogen-free certification is contractually required.

FAQ
What does the "CA" suffix indicate in SMCJ10CAHE3/57T?
The "CA" suffix denotes a bidirectional configuration: SMCJ10CAHE3/57T provides symmetrical clamping for both positive and negative voltage transients, unlike unidirectional variants (e.g., SMCJ10A). This eliminates polarity concerns during PCB layout and supports AC-coupled or floating signal paths - essential for RS-485, CAN FD, and sensor bridge circuits where voltage swings occur in either direction.
Is SMCJ10CAHE3/57T qualified for automotive applications?
Yes, SMCJ10CAHE3/57T carries the HE3 suffix, confirming it is RoHS-compliant and AEC-Q101 qualified. It has passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per ANSI/ESDA/JEDEC JS-001 - making it suitable for engine control units, body control modules, and ADAS sensors where reliability under thermal and electrical stress is mandatory.
What is the maximum clamping voltage of SMCJ10CAHE3/57T under surge conditions?
The maximum clamping voltage (VC) of SMCJ10CAHE3/57T is 17.0 V when subjected to an 88.2 A peak pulse current with a 10/1000 µs waveform. This value is measured per JEDEC standards and guarantees that downstream components - such as 5 V microcontrollers or 3.3 V transceivers - experience no more than 17.0 V during worst-case transients, preserving functional safety margins.
Can SMCJ10CAHE3/57T be used in place of a unidirectional TVS like SMCJ10A?
No - SMCJ10CAHE3/57T is strictly bidirectional and lacks cathode/anode polarity marking, whereas SMCJ10A is unidirectional with a defined cathode band. Substituting them requires verifying circuit topology: SMCJ10CAHE3/57T is appropriate for AC signals or floating buses; SMCJ10A suits DC power rails where reverse conduction must be blocked. Layout changes and functional validation are required for any replacement.
What is the thermal resistance profile of SMCJ10CAHE3/57T, and why does it matter?
SMCJ10CAHE3/57T has a typical junction-to-lead thermal resistance (RθJL) of 15 °C/W and junction-to-ambient (RθJA) of 75 °C/W. Low RθJL enables rapid heat dissipation into PCB copper pads - critical for sustaining repetitive surge events without thermal runaway. When mounted on 8.0 mm × 8.0 mm copper pads per Vishay's recommended layout, it maintains clamping performance across multiple transients in automotive and industrial duty cycles.
