Product details
Overview
SMCJ13CAHE3/9AT 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 13 V standoff voltage (VWM), 21.5 V maximum clamping voltage (VC) at 69.8 A peak pulse current (IPPM), and 1500 W peak pulse power (10/1000 µs waveform), commonly deployed on automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the SMCJ13CAHE3/9AT datasheet, SMCJ13CAHE3/9AT pinout, SMCJ13CAHE3/9AT application, or SMCJ13CAHE3/9AT equivalent, key selection criteria include bidirectional surge capability, AEC-Q101 qualification, low clamping ratio (VC/VWM = 1.65), MSL Level 1 moisture sensitivity, and RoHS-compliant matte tin plating compatible with J-STD-002 soldering standards.
Technical Context
This device operates as a voltage-clamping protector using an avalanche breakdown mechanism, with symmetrical bidirectional conduction enabling suppression of both positive and negative transients without polarity dependency. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the low incremental surge resistance supports fast energy dissipation during ESD or lightning-induced surges.
The SMCJ13CAHE3/9AT is rated for -55 °C to +150 °C operating junction temperature and exhibits a typical thermal resistance of 75 °C/W (junction-to-ambient) on standard 8.0 mm × 8.0 mm copper pads. Its 10/1000 µs waveform rating reflects standardized surge immunity testing per ANSI/IEEE C62.35, and it meets UL 497B recognition for protector classification (QVGQ2).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA-E3/61T | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher VC/VWM ratio (1.85) | Not suitable for high-energy automotive load dump; limited to low-power signal lines | Select when board space is constrained and surge energy is ≤400 W |

FAQ
What is the clamping voltage of SMCJ13CAHE3/9AT at its rated peak pulse current?
The SMCJ13CAHE3/9AT has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current (IPPM) of 69.8 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCJ13CAHE3/9AT maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is SMCJ13CAHE3/9AT suitable for automotive applications?
Yes, SMCJ13CAHE3/9AT is AEC-Q101 qualified and explicitly designated for automotive use with ordering code suffix "HE3". It meets requirements for under-hood and chassis-mounted electronics, including protection of CAN transceivers, sensor signal paths, and power distribution nodes subject to load dump and ISO 7637-2 pulses. The SMCJ13CAHE3/9AT also carries UL 497B recognition (file E136766) for automotive protector classification.
What does the "CA" suffix indicate in SMCJ13CAHE3/9AT?
The "CA" suffix in SMCJ13CAHE3/9AT denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., SMCJ13A), the SMCJ13CAHE3/9AT has no cathode band marking and functions identically regardless of terminal orientation. Electrical characteristics-including VBR, VWM, and VC-apply equally in both directions.
What is the thermal resistance of SMCJ13CAHE3/9AT, and how does it affect PCB layout?
The SMCJ13CAHE3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. This value assumes minimum recommended pad layout per Vishay's DO-214AB outline. To maintain safe junction temperatures during repetitive surges, designers must provide adequate copper area and avoid excessive trace length; the SMCJ13CAHE3/9AT's RθJL of 15 °C/W indicates efficient heat transfer to PCB leads.
Does SMCJ13CAHE3/9AT require special handling or baking before reflow soldering?
No, SMCJ13CAHE3/9AT is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and may be reflowed directly without pre-baking-even at peak temperatures up to 260 °C. This eliminates moisture sensitivity concerns and simplifies manufacturing flow. The SMCJ13CAHE3/9AT's molding compound meets UL 94 V-0 flammability rating, and its matte tin-plated leads comply with J-STD-002 solderability standards.
