Product details
Overview
SMCJ10C-E3/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for clamping voltage transients on signal or power lines. It features a 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage at 88.2 A peak pulse current, 1500 W peak pulse power rating, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMCJ10C-E3/57T datasheet, SMCJ10C-E3/57T pinout, SMCJ10C-E3/57T application, or SMCJ10C-E3/57T equivalent, key selection criteria include bi-directional clamping capability, 10/1000 μs surge waveform handling, low incremental surge resistance, and compatibility with automated SMT assembly on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ10C-E3/57T operates as a voltage-clamping protection device that responds within picoseconds to transient overvoltages induced by inductive switching or ESD events. Its bi-directional architecture enables symmetrical clamping in both polarities without polarity marking, and its glass-passivated junction ensures stable breakdown characteristics under repeated surge stress.
Designed for surface-mount applications, it delivers 1500 W peak pulse power dissipation with a 10/1000 μs waveform while maintaining a low thermal resistance of 15 °C/W (junction-to-lead) and operating across -55 °C to +150 °C junction temperature range. It meets MSL Level 1 per J-STD-020 and passes JESD 201 Class 1A whisker testing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA-E3/52T | Lower PPPM (600 W), smaller SMB package (DO-214AA), same VWM and VC | Suitable for space-constrained consumer ports but not for high-energy industrial surges | Select when board area is critical and surge energy remains ≤600 W |
| 1.5KE10CA | Through-hole TO-218 package, identical electrical specs, higher thermal mass | Better suited for prototyping or legacy through-hole designs; not SMT-compatible | Choose for manual assembly or where reflow compatibility is not required |
Compared with SMCJ10C-E3/57T, SMBJ10CA-E3/52T offers footprint reduction at the cost of 60% lower surge power handling, while 1.5KE10CA provides identical clamping performance in a through-hole form factor-neither is pin-compatible, but both serve overlapping protection roles in different mechanical contexts.

FAQ
What is the clamping voltage of SMCJ10C-E3/57T under a 10/1000 μs surge?
The SMCJ10C-E3/57T has a maximum clamping voltage (VC) of 17.0 V when subjected to its rated peak pulse current of 88.2 A using the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and verified at TA = 25 °C on 8.0 mm × 8.0 mm copper pads. The SMCJ10C-E3/57T maintains this clamping performance across its full operating temperature range.
Is SMCJ10C-E3/57T suitable for automotive applications?
Yes, SMCJ10C-E3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its DO-214AB package meets MSL Level 1, and its -55 °C to +150 °C operating junction temperature range supports under-hood deployment. The SMCJ10C-E3/57T also complies with JESD 201 Class 1A whisker testing and UL 497B recognition.
How does the bi-directional design of SMCJ10C-E3/57T affect circuit layout?
The SMCJ10C-E3/57T has no polarity marking and functions identically in either orientation, simplifying PCB layout for AC-coupled or floating lines such as RS-485, CAN, or audio signals. Unlike uni-directional TVS diodes, the SMCJ10C-E3/57T eliminates risk of incorrect placement during automated assembly and avoids need for orientation-aware footprints. Its symmetric behavior is confirmed in the datasheet for all electrical parameters.
What is the leakage current specification for SMCJ10C-E3/57T at its stand-off voltage?
At its 10 V stand-off voltage (VWM), the SMCJ10C-E3/57T exhibits a maximum reverse leakage current (ID) of 5.0 μA at TA = 25 °C. This low leakage preserves signal integrity in high-impedance circuits such as sensor bias networks or precision reference paths. The SMCJ10C-E3/57T maintains specified leakage performance across its full operating temperature range per the manufacturer's derating curves.
Does SMCJ10C-E3/57T require special PCB pad design for thermal performance?
Yes-the SMCJ10C-E3/57T achieves its rated 1500 W peak pulse power only when mounted on the minimum recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, as defined in the Vishay datasheet. Smaller pads reduce thermal dissipation and degrade surge current capability. The SMCJ10C-E3/57T's RθJL of 15 °C/W assumes this layout; deviating requires derating per Figure 2 in Document Number 88394.
