Product details
Overview
SMCJ100CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 100 V standoff voltage, 1500 W peak pulse power rating, and 162 V maximum clamping voltage at 9.3 A peak pulse current. It protects sensitive ICs, MOSFETs, and sensor signal lines in automotive, industrial, and telecom systems against inductive switching transients and lightning-induced surges.
For engineers reviewing the SMCJ100CAHE3_A/H datasheet, SMCJ100CAHE3_A/H pinout, SMCJ100CAHE3_A/H application, or SMCJ100CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 100 V VWM, 162 V VC at IPPM, and compatibility with automated SMT assembly on standard PCB copper pads.
Technical Context
This device operates as a voltage-clamped transient suppressor using an avalanche breakdown mechanism, with symmetrical bidirectional conduction enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM).
The SMCJ100CAHE3_A/H delivers 1500 W peak pulse power handling per 10/1000 µs waveform under standardized test conditions, with thermal resistance RθJA = 75 °C/W and RθJL = 15 °C/W, supporting reliable operation up to TJ = +150 °C in compact SMC footprint layouts.

FAQ
What is the maximum clamping voltage of the SMCJ100CAHE3_A/H under rated surge conditions?
The SMCJ100CAHE3_A/H has a maximum clamping voltage (VC) of 162 V when subjected to its rated 9.3 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during a full 1500 W transient event. The SMCJ100CAHE3_A/H maintains this clamping performance across its qualified operating temperature range.
Is the SMCJ100CAHE3_A/H suitable for automotive applications?
Yes, the SMCJ100CAHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix. It meets stress test requirements for temperature cycling, humidity bias, mechanical shock, and accelerated life testing. Its 1500 W surge rating and +150 °C maximum junction temperature make the SMCJ100CAHE3_A/H appropriate for engine control, body electronics, and ADAS subsystems exposed to load dump and ISO 7637-2 transients.
Does the SMCJ100CAHE3_A/H have polarity markings on the package?
No, the SMCJ100CAHE3_A/H is a bidirectional TVS diode and carries no polarity marking on the SMC (DO-214AB) case. Unlike unidirectional variants that feature a cathode band, the SMCJ100CAHE3_A/H uses symmetrical internal structure so either terminal functions identically under positive or negative transients-eliminating orientation constraints during automated placement and simplifying PCB layout.
What is the reverse leakage current specification for the SMCJ100CAHE3_A/H at its standoff voltage?
The SMCJ100CAHE3_A/H exhibits a maximum reverse leakage current (ID) of 1.0 µA when biased at its 100 V standoff voltage (VWM), measured at TA = 25 °C. This low leakage ensures minimal power loss and signal distortion in high-impedance sensing or communication circuits. The SMCJ100CAHE3_A/H maintains this specification across its full operating temperature range, supporting stable performance in battery-powered and precision analog systems.
How does the SMCJ100CAHE3_A/H compare to unidirectional SMCJ100AHE3_A/H in circuit implementation?
The SMCJ100CAHE3_A/H differs from the unidirectional SMCJ100AHE3_A/H solely in polarity behavior: the "CA" version clamps symmetrically for both polarities, while the "A" version conducts only in reverse bias and blocks forward current. In practice, the SMCJ100CAHE3_A/H replaces two unidirectional devices in AC-coupled or floating differential lines, reducing component count and eliminating risk of incorrect orientation. Both share identical VWM, VC, PPPM, and package.
