Product details
Overview
SMCJ10CA-E3/57T 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 10 V standoff voltage (VWM), 1500 W peak pulse power (PPPM), and 17.0 V clamping voltage (VC) at 88.2 A peak pulse current (IPPM). 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 SMCJ10CA-E3/57T datasheet, SMCJ10CA-E3/57T pinout, SMCJ10CA-E3/57T application, or SMCJ10CA-E3/57T equivalent, key selection criteria include bidirectional clamping capability, 1500 W surge rating, 10 V stand-off voltage, -55 °C to +150 °C operating temperature range, and RoHS-compliant commercial-grade packaging with matte tin leads.
Technical Context
The SMCJ10CA-E3/57T operates as a voltage-clamping device that enters avalanche breakdown when reverse voltage exceeds its breakdown range (11.1–12.3 V at 1 mA test current), limiting transient energy by diverting surge current to ground. Its bidirectional symmetry ensures identical clamping behavior in both polarities, eliminating polarity concerns in AC-coupled or floating signal paths.
Thermally, it features a junction-to-lead thermal resistance of 15 °C/W and junction-to-ambient of 75 °C/W under standard pad layout, enabling reliable operation up to 150 °C junction temperature. It meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements.

FAQ
What is the clamping voltage of the SMCJ10CA-E3/57T under a 10/1000 µs surge?
The SMCJ10CA-E3/57T clamps to a maximum of 17.0 V when subjected to its rated 88.2 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured at the device terminals under specified test conditions (TA = 25 °C, mounted on 8.0 mm × 8.0 mm copper pads), and represents the upper voltage limit imposed on protected circuitry during surge events. The SMCJ10CA-E3/57T maintains this clamping performance consistently across its operational temperature range.
Is the SMCJ10CA-E3/57T suitable for automotive applications?
The SMCJ10CA-E3/57T is a commercial-grade, RoHS-compliant variant certified to MSL Level 1 and JESD201 Class 2 whisker resistance, making it suitable for non-safety-critical automotive subsystems such as infotainment, body control, and sensor interfaces. For AEC-Q101-qualified deployment, Vishay offers the SMCJ10CAHE3 variant (same electrical specs, enhanced qualification). The SMCJ10CA-E3/57T itself is not AEC-Q101 certified but shares identical die and package construction with the qualified version.
How does the bidirectional nature of the SMCJ10CA-E3/57T affect PCB layout?
The SMCJ10CA-E3/57T has no polarity marking and exhibits identical electrical characteristics in both directions, allowing placement across any two-node connection without orientation constraints-ideal for differential pairs (e.g., CAN, RS-485), AC-coupled signals, or floating grounds. Unlike unidirectional TVS diodes, the SMCJ10CA-E3/57T eliminates risk of incorrect installation and simplifies automated assembly. Its SMC (DO-214AB) footprint remains unchanged regardless of signal polarity.
What is the maximum reverse leakage current of the SMCJ10CA-E3/57T at its stand-off voltage?
At its 10 V stand-off voltage (VWM), the SMCJ10CA-E3/57T exhibits a maximum reverse leakage current (ID) of 5.0 µA at 25 °C. This low leakage ensures minimal impact on high-impedance circuits such as sensor bias networks or precision reference paths. Leakage increases with temperature but remains below 50 µA up to 85 °C, supporting stable operation in extended ambient conditions without degrading signal fidelity.
Can the SMCJ10CA-E3/57T be used in parallel for higher surge current handling?
No-parallel connection of SMCJ10CA-E3/57T units is not recommended due to parameter mismatch (VBR tolerance ±5 %) causing uneven current sharing and potential thermal runaway. For higher surge capacity, select a single higher-rated device (e.g., SMCJ15CA-E3/57T) or implement staged protection with upstream current-limiting impedance. The SMCJ10CA-E3/57T is characterized and tested as a standalone 1500 W device; its performance assumes proper PCB thermal design per Vishay's 8.0 mm × 8.0 mm pad layout recommendation.
