Product details
Overview
SMCJ100CAHE3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection on power and signal lines. It features 100 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), clamping voltage of 162 V at 9.3 A IPPM, and operates across -55 °C to +150 °C junction temperature - deployed in automotive power supply rails and industrial sensor interfaces.
For engineers reviewing the SMCJ100CAHE3/57T datasheet, SMCJ100CAHE3/57T pinout, SMCJ100CAHE3/57T application, or SMCJ100CAHE3/57T equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, 1500 W surge rating with 10/1000 µs waveform, low thermal resistance (RθJL = 15 °C/W), and RoHS-compliant matte tin terminations suitable for automated SMT placement.
Technical Context
The SMCJ100CAHE3/57T is a glass-passivated, avalanche-breakdown TVS diode optimized for fast response (<1 ns) to ESD and lightning-induced transients. Its bidirectional architecture enables symmetrical clamping in both polarities without polarity marking, supporting protection of AC-coupled or floating signal paths.
It delivers 162 V maximum clamping voltage at 9.3 A peak pulse current (10/1000 µs), with 0.107 %/°C temperature coefficient of breakdown voltage and 1.0 µA max reverse leakage at 100 V - ensuring stable performance under thermal stress and low standby power loss.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A-E3/61T | Lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 100 °C/W) | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial use | Select when space-constrained layouts prioritize size over automotive qualification and surge margin |
| SMCJ100AHE3/57T | Unidirectional version; cathode band marking; identical VWM, VC, and PPPM | Requires polarity-aware PCB layout; unsuitable for AC or floating differential lines | Choose only for DC-biased unidirectional rails where polarity is fixed and known |

FAQ
What is the clamping voltage of SMCJ100CAHE3/57T at its rated peak pulse current?
The SMCJ100CAHE3/57T has a maximum clamping voltage (VC) of 162 V at 9.3 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value ensures downstream components see no more than 162 V during standardized surge events, directly supporting design margin calculations for 100 V-rated circuitry. The SMCJ100CAHE3/57T maintains this clamping performance across its full operating temperature range.
Is SMCJ100CAHE3/57T suitable for automotive applications?
Yes, SMCJ100CAHE3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its +150 °C maximum junction temperature, MSL Level 1 reflow compatibility, and validation against mechanical, thermal, and electrical stress tests make it appropriate for engine control units, body electronics, and ADAS sensor modules. The SMCJ100CAHE3/57T meets automotive reliability requirements without derating.
How does the bidirectional design of SMCJ100CAHE3/57T affect PCB layout?
The SMCJ100CAHE3/57T has no polarity marking and functions identically in both directions, eliminating orientation constraints during placement. This simplifies PCB layout for AC-coupled lines, differential buses (e.g., CAN, RS-485), or floating sensors where voltage polarity may reverse. Unlike unidirectional variants such as SMCJ100AHE3/57T, the SMCJ100CAHE3/57T requires no cathode band alignment, reducing assembly errors and enabling symmetric routing.
What is the thermal resistance from junction to lead (RθJL) for SMCJ100CAHE3/57T?
The SMCJ100CAHE3/57T has a typical junction-to-lead thermal resistance (RθJL) of 15 °C/W, measured per JEDEC standards. This low value enables efficient heat transfer from the silicon die to the PCB copper pads via the leads, minimizing thermal derating of surge capability at elevated ambient temperatures. For the SMCJ100CAHE3/57T, this supports reliable operation even when mounted on minimal 8 mm × 8 mm copper pads per datasheet Fig. 2.
Does SMCJ100CAHE3/57T meet RoHS and halogen-free requirements?
Yes, SMCJ100CAHE3/57T is RoHS-compliant and carries the HE3 suffix, indicating compliance with EU RoHS Directive 2011/65/EU and exemption 7(c)-I. It is not halogen-free - that designation applies to HM3-suffixed variants. The SMCJ100CAHE3/57T uses matte tin-plated leads and meets JESD 201 Class 2 whisker resistance, satisfying environmental and reliability requirements for commercial and automotive applications.
