Product details
Overview
SMCJ90CAHE3_A/I 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 1500 W peak pulse power rating, 90 V standoff voltage (VWM), and 146 V maximum clamping voltage (VC) at 10.3 A IPPM under 10/1000 µs waveform. 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 SMCJ90CAHE3_A/I datasheet, SMCJ90CAHE3_A/I pinout, SMCJ90CAHE3_A/I application, or SMCJ90CAHE3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 1500 W surge handling, low thermal resistance (RθJL = 15 °C/W), and compatibility with automated SMT placement on standard PCB copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within picoseconds to transient overvoltages exceeding its breakdown threshold (VBR min = 100 V, max = 111 V at IT = 1 mA). Its bidirectional symmetry ensures identical clamping behavior in both polarities, eliminating polarity marking requirements.
Designed for robustness in harsh environments, SMCJ90CAHE3_A/I features glass-passivated junctions, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and delivers stable performance across -55 °C to +150 °C junction temperature range with 0.106 %/°C VBR temperature coefficient.

FAQ
What is the breakdown voltage range for SMCJ90CAHE3_A/I?
The SMCJ90CAHE3_A/I has a guaranteed breakdown voltage (VBR) range of 100 V to 111 V at 1 mA test current, measured per ANSI/IEEE C62.35 standards. This bidirectional specification applies equally in both polarities and ensures consistent clamping onset across voltage transients regardless of polarity. The value is confirmed in Vishay's official datasheet revision 09-Jan-2024, Document Number 88394.
Is SMCJ90CAHE3_A/I qualified for automotive use?
Yes, SMCJ90CAHE3_A/I is AEC-Q101 qualified, as indicated by the "HE3" suffix in its ordering code. It undergoes rigorous stress testing including temperature cycling, high-temperature operating life, and mechanical shock per AEC-Q101 Rev D. This qualification validates its suitability for under-hood and chassis-mounted applications in passenger vehicles and commercial vehicles.
What is the maximum clamping voltage of SMCJ90CAHE3_A/I during a surge event?
The maximum clamping voltage (VC) of SMCJ90CAHE3_A/I is 146 V at 10.3 A peak pulse current (IPPM), tested with a 10/1000 µs waveform. This value represents the upper limit of voltage seen by protected circuitry during worst-case surge conditions and is critical for ensuring downstream components remain within their absolute maximum ratings.
Does SMCJ90CAHE3_A/I require polarity-aware PCB layout?
No, SMCJ90CAHE3_A/I does not require polarity-aware layout because it is a bidirectional TVS diode. Unlike unidirectional variants (e.g., SMCJ90AHE3_A/I), it has no cathode band marking and conducts identically in both directions. This simplifies design for AC-coupled lines, floating grounds, and differential signal paths where voltage polarity reversal is possible.
What is the thermal resistance from junction to lead for SMCJ90CAHE3_A/I?
The typical thermal resistance from junction to lead (RθJL) for SMCJ90CAHE3_A/I is 15 °C/W, as specified in the Thermal Characteristics table of the Vishay datasheet. This low value enables efficient heat transfer from the silicon die to the PCB copper pads through the device leads, supporting reliable operation at elevated ambient temperatures and during repetitive surge events.
