Product details
Overview
SMCJ10CA/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection on signal and power lines. It features a 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage (VC) at 88.2 A peak pulse current (IPPM), and 1500 W peak pulse power dissipation (PPPM) with 10/1000 µs waveform - ideal for safeguarding automotive sensor interfaces and industrial I/O circuits against ESD and inductive switching transients.
For engineers reviewing the SMCJ10CA/57T datasheet, SMCJ10CA/57T pinout, SMCJ10CA/57T application, or SMCJ10CA/57T equivalent, key selection criteria include its bi-directional symmetry, AEC-Q101 qualification, 150 °C junction temperature rating, low incremental surge resistance, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
The SMCJ10CA/57T operates as a voltage-clamping device using an avalanche breakdown mechanism, with symmetrical electrical characteristics in both forward and reverse directions due to its bi-directional construction. Its glass-passivated junction ensures stable breakdown behavior and long-term reliability under repetitive surge stress.
Designed for surface-mount implementation on 8.0 mm × 8.0 mm copper pads per terminal, it delivers thermal performance with RθJA = 75 °C/W and RθJL = 15 °C/W, enabling effective heat dissipation without heatsinking in typical industrial and automotive ambient conditions up to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected circuitry. |
| VBR min/max | 11.1 V / 12.3 V at 1.0 mA - Confirmed breakdown voltage window ensuring predictable turn-on during transients. |
| VC @ IPPM | 17.0 V at 88.2 A - Clamping voltage under full 1500 W surge; limits downstream voltage stress during worst-case events. |
| PPPM | 1500 W - Peak pulse power handling capability with 10/1000 µs waveform; meets IEC 61000-4-5 Level 4 surge immunity requirements. |
| ID @ VWM | 5.0 µA - Reverse leakage at stand-off voltage; low enough to avoid interference in high-impedance sensor or communication lines. |
| TJ max | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive and industrial environments. |
| MSL Level | Level 1 (J-STD-020) - No floor life limitation; suitable for standard reflow without dry pack or baking. |
Pinout & Package
Package: DO-214AB (SMCJ), surface-mount, bi-directional configuration with no polarity marking - terminals are symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC10CA | Lower PPPM (600 W), same VWM (10 V), smaller DO-214AC (SMA) package | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 compliance | Select when board space is constrained and surge threat level is limited to IEC 61000-4-2 ESD only. |
| 1.5KE10CA | Higher VBR (11.1–12.3 V), same VC (17.0 V), axial-leaded DO-15 package | Not surface-mount; incompatible with automated assembly; higher thermal resistance limits power handling in dense layouts | Choose only for through-hole prototyping or legacy repair where SMT is unavailable. |
Compared with SAC10CA and 1.5KE10CA, the SMCJ10CA/57T uniquely combines 1500 W surge capacity, AEC-Q101 qualification, and DO-214AB SMT compatibility - making it the preferred choice for production-grade automotive and industrial designs requiring validated reliability and automated manufacturability.

FAQ
What is the clamping voltage of the SMCJ10CA/57T under maximum surge conditions?
The SMCJ10CA/57T has a maximum clamping voltage (VC) of 17.0 V when subjected to its rated peak pulse current (IPPM) of 88.2 A with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream circuitry remains within safe voltage limits during transient events. The SMCJ10CA/57T maintains this clamping performance across its full operating temperature range of –55 °C to +150 °C.
Is the SMCJ10CA/57T suitable for automotive applications?
Yes, the SMCJ10CA/57T is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its bi-directional symmetry, 150 °C junction temperature rating, and robust surge handling make it appropriate for under-hood and cabin environments subject to ISO 7637-2 and IEC 61000-4-5 stress. The SMCJ10CA/57T meets all required test conditions defined in the AEC-Q101 standard for transient voltage suppressors.
Does the SMCJ10CA/57T require polarity-aware PCB layout?
No - the SMCJ10CA/57T is a bi-directional TVS diode with no cathode marking or polarity designation. Both terminals are electrically identical, allowing unrestricted orientation during automated placement. This simplifies PCB design and eliminates risk of misorientation-related failures. The SMCJ10CA/57T achieves symmetrical clamping behavior in either direction, delivering identical VBR, VC, and IPPM performance regardless of signal polarity.
What is the thermal resistance of the SMCJ10CA/57T in standard mounting conditions?
When mounted on the recommended 8.0 mm × 8.0 mm copper pads per terminal, the SMCJ10CA/57T exhibits a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15 °C/W. These values enable reliable operation at full 1500 W surge power without external heatsinking in ambient temperatures up to +125 °C. The SMCJ10CA/57T's thermal performance is validated per JEDEC JESD51-7 and documented in Vishay's datasheet Figure 5.
How does the SMCJ10CA/57T compare to uni-directional variants like SMCJ10A?
The SMCJ10CA/57T differs from the uni-directional SMCJ10A by providing symmetrical clamping in both polarities, eliminating the need for polarity awareness in AC-coupled or bidirectional signal paths. While both share identical VWM (10 V), VBR (11.1–12.3 V), and VC (17.0 V), only the SMCJ10CA/57T supports applications such as differential data lines, AC power rails, or floating sensor outputs. The SMCJ10CA/57T also omits the cathode band marking present on SMCJ10A.
