Product details
Overview
SMCJ64CAHE3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 1500 W peak pulse power rating, 64 V standoff voltage (VWM), and 103 V maximum clamping voltage (VC) at 14.6 A IPPM under 10/1000 µs waveform. It protects sensitive ICs and MOSFETs in automotive power supplies and industrial sensor interfaces.
For engineers reviewing the SMCJ64CAHE3/57T datasheet, SMCJ64CAHE3/57T pinout, SMCJ64CAHE3/57T application, or SMCJ64CAHE3/57T equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 1500 W surge rating, low thermal resistance (RθJL = 15 °C/W), and RoHS-compliant matte tin-plated leads suitable for automated SMT placement.
Technical Context
This TVS diode operates as a voltage-clamping device across signal or power lines, responding to transients within picoseconds via avalanche breakdown. Its bidirectional symmetry ensures identical clamping behavior in both polarities, eliminating polarity concerns in AC-coupled or floating circuits.
Designed for surface-mount use on 8.0 mm × 8.0 mm copper pads, it delivers stable performance up to +150 °C junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. The glass-passivated junction ensures robust reliability under repetitive surge stress.

Applications
| Automotive Power Distribution | Industrial Sensor Signal Lines |
|---|---|
Use Scenario: Protection of 12 V supply rails feeding body control modules and lighting drivers against load dump and alternator transients. IC Role / Device Role / Timing Role: Voltage-clamping TVS placed directly at module input, shunting surge current away from DC-DC converters and microcontrollers.

| Telecom Line Interface | Consumer Device USB Ports |
Use Scenario: Surge suppression on Ethernet PHY interface lines exposed to lightning-induced surges in outdoor telecom equipment. IC Role / Device Role / Timing Role: Primary protection stage before secondary TVS or integrated ESD arrays, handling bulk energy dissipation. Use Value: 1500 W rating absorbs high-energy common-mode transients while maintaining low capacitance (< 100 pF) to preserve signal integrity. | Use Scenario: Input-side protection of USB 2.0 data lines and VBUS in portable audio/video devices subjected to user-handling ESD. IC Role / Device Role / Timing Role: Fast-response bidirectional clamp across D+/D− and VBUS-to-GND, preventing latch-up in USB transceivers. Use Value: Sub-nanosecond response time and AEC-Q101 qualification ensure robustness in high-volume consumer manufacturing environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC64CA-E3/57T | Same VWM (64 V) and PPPM (1500 W), but lower VC (98 V) and higher IPPM (15.3 A); SAC series has tighter VBR tolerance (±5 % vs. ±10 %) | Better clamping performance for margin-critical designs; not AEC-Q101 qualified | Select when tighter breakdown tolerance and lower clamping voltage are prioritized over automotive qualification |
| SMCJ64CAHM3/57T | Identical electrical specs and AEC-Q101 qualification; halogen-free construction (per IEC 61249-2-21) vs. standard RoHS | Required for compliance with halogen-free mandates in EU industrial and medical equipment | Select when halogen-free material compliance is mandatory for end-product certification |
Compared with SMCJ64CAHE3/57T, SAC64CA-E3/57T offers superior clamping but lacks automotive qualification, while SMCJ64CAHM3/57T matches all performance and reliability specs with halogen-free materials-making it ideal for regulated industrial deployments.

FAQ
What is the clamping voltage of SMCJ64CAHE3/57T at its rated peak pulse current?
The SMCJ64CAHE3/57T has a maximum clamping voltage (VC) of 103 V at 14.6 A peak pulse current (IPPM), measured under the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is confirmed in the Vishay datasheet revision 09-Jan-2024, page 2.
Is SMCJ64CAHE3/57T suitable for automotive applications?
Yes, SMCJ64CAHE3/57T is AEC-Q101 qualified, explicitly designated for automotive use with suffix "HE3". It undergoes stress testing for high-temperature operating life, temperature cycling, and ESD robustness, making it appropriate for engine control units, body electronics, and ADAS power supplies.
What does the "CA" suffix indicate in SMCJ64CAHE3/57T?
The "CA" suffix in SMCJ64CAHE3/57T denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Electrical characteristics-including VBR, VC, and IPPM-apply identically in either direction, eliminating polarity constraints during PCB layout.
What is the thermal resistance from junction to lead for SMCJ64CAHE3/57T?
The typical thermal resistance from junction to lead (RθJL) for SMCJ64CAHE3/57T is 15 °C/W, as specified in the Vishay datasheet section "THERMAL CHARACTERISTICS". This low value supports effective heat conduction into the PCB copper pads, enabling reliable operation under repetitive surge conditions.
Does SMCJ64CAHE3/57T require special handling during reflow soldering?
No, SMCJ64CAHE3/57T is rated MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 260 °C, allowing standard lead-free reflow profiles without pre-baking. Its moisture sensitivity level confirms suitability for uninterrupted SMT line integration in high-volume manufacturing.
