Product details
Overview
SMCJ10-E3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of sensitive electronics. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V clamping voltage (VC) at 88.2 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform.
For engineers reviewing the SMCJ10-E3/57T datasheet, SMCJ10-E3/57T pinout, SMCJ10-E3/57T application, or SMCJ10-E3/57T equivalent, key selection criteria include clamping performance under 8.3 ms surge, thermal resistance (RθJA = 75 °C/W), AEC-Q101 qualification status, RoHS compliance (E3 suffix), and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ10-E3/57T operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology for stable breakdown behavior and low incremental surge resistance. Its clamping action limits transient-induced voltage excursions to ≤17.0 V during 1500 W surges, enabling protection of downstream ICs, MOSFETs, and sensor signal lines against inductive switching and lightning-induced transients.
Designed for surface-mount use in automotive, industrial, and telecom systems, it meets MSL Level 1 per J-STD-020 (260 °C peak reflow), supports 200 A non-repetitive forward surge (IFSM), and maintains operation across –55 °C to +150 °C junction temperature range with 6.5 W steady-state power dissipation at TA = 50 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 11.1 V / 12.3 V at IT = 1 mA - Confirmed avalanche onset range under standardized test conditions |
| VC @ IPPM | 17.0 V at 88.2 A - Clamped voltage during full 1500 W transient, defining protected circuit stress level |
| PPPM | 1500 W - Peak surge power handling capability with 10/1000 µs waveform, critical for IEC 61000-4-5 compliance margin |
| TJ max | +150 °C - Maximum junction temperature enabling high-ambient deployment in engine control or power supply modules |
| RθJA | 75 °C/W - Thermal resistance from junction to ambient on standard 8 mm × 8 mm pad layout, guiding heatsinking requirements |
Pinout & Package
Package: DO-214AB (SMCJ), low-profile surface-mount case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; polarity indicated by cathode band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to ground or lower-potential rail in unidirectional clamp configuration |
| Cathode (banded end) | Avalanche clamping terminal | Connected to protected line; conducts during overvoltage to shunt surge current to ground |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under repeated surge stress without parameter drift |
| AEC-Q101 qualification | Validated for automotive-grade deployment including engine control units and ADAS sensor interfaces |
| MSL Level 1 rating | Enables single-reflow assembly without moisture-related cracking risk (peak 260 °C) |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving protection margin for 3.3 V/5 V logic rails |
Applications
| Automotive Power Line Protection | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load-dump and alternator ripple transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and ground to clamp surges above 10 V. Use Value: Limits transient voltage to ≤17.0 V, preventing damage to microcontrollers and CAN transceivers rated for 16 V absolute maximum. | Use Scenario: Shielding analog output lines of pressure/temperature sensors in PLC I/O modules. IC Role / Device Role / Timing Role: Clamp device on 4–20 mA or 0–10 V signal path to suppress ESD and field-induced spikes. Use Value: Fast response time and low clamping voltage preserve signal integrity while meeting IEC 61000-4-2 Level 4 (15 kV air) immunity targets. |

IC Role / Device Role / Timing Role: Standoff-rated TVS in series with polyfuse to limit fault energy during hot-plug events. Use Value: 10 V VWM ensures no conduction during normal 5 V operation; 17.0 V VC prevents USB PHY latch-up during ESD events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A-E3/52T | Lower PPPM (600 W), smaller SMB (DO-214AA) package, same VWM/VBR/VC specs | Reduced surge handling; suitable only for lower-energy threats (e.g., board-level ESD) | Select when space-constrained layouts preclude DO-214AB and threat level is limited to IEC 61000-4-2, not IEC 61000-4-5 |
| SMCJ10AHE3/57T | Identical electrical specs but AEC-Q101 qualified (HE3 suffix vs. E3); same DO-214AB package | Required for automotive OEM designs requiring component-level qualification evidence | Choose SMCJ10AHE3/57T for Tier 1 automotive BOMs; SMCJ10-E3/57T suffices for industrial/commercial use |
Compared with SMBJ10A-E3/52T, the SMCJ10-E3/57T delivers 2.5× higher surge power handling in a larger footprint; versus SMCJ10AHE3/57T, it offers identical protection performance without formal AEC-Q101 documentation-making it optimal for cost-sensitive industrial applications where qualification is not mandated.

FAQ
What is the clamping voltage of the SMCJ10-E3/57T under maximum surge conditions?
The SMCJ10-E3/57T exhibits a maximum clamping voltage (VC) of 17.0 V when subjected to its rated peak pulse current (IPPM) of 88.2 A using the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on the protected circuit during worst-case transient events and is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per the datasheet test condition.
Is the SMCJ10-E3/57T suitable for automotive applications?
The SMCJ10-E3/57T is RoHS-compliant and manufactured with processes meeting JESD201 Class 1A whisker resistance, but it carries the commercial-grade E3 suffix-not the HE3 (AEC-Q101 qualified) variant. Therefore, while its electrical and thermal specs align with automotive environments, formal AEC-Q101 certification applies only to SMCJ10AHE3/57T. For non-OEM automotive subsystems where qualification is not contractually required, the SMCJ10-E3/57T remains functionally appropriate.
How does the SMCJ10-E3/57T differ from the SMCJ10A variant?
The SMCJ10-E3/57T and SMCJ10A refer to the same base device-the "A" denotes unidirectional polarity, which is inherent to this part number. The "E3/57T" suffix specifies RoHS compliance (E3) and packaging in 7-inch tape-and-reel (57T). No functional or parametric difference exists between SMCJ10A and SMCJ10-E3/57T; the latter is the full orderable manufacturer part number used for procurement and logistics tracking.
What is the thermal resistance and maximum junction temperature of the SMCJ10-E3/57T?
The SMCJ10-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pad layout. Its maximum operating junction temperature (TJ max) is +150 °C, supporting reliable operation in high-ambient environments such as under-hood automotive modules or enclosed industrial power supplies where airflow is limited.
Can the SMCJ10-E3/57T be used in bi-directional protection circuits?
No-the SMCJ10-E3/57T is explicitly a unidirectional TVS diode, as indicated by the absence of the "CA" suffix (e.g., SMCJ10CA). Its cathode band marks polarity, and it conducts only in reverse bias during overvoltage events. For bi-directional applications-such as AC line protection or differential signal lines-engineers must select the CA-suffixed variant (e.g., SMCJ10CA) or use back-to-back unidirectional devices; using SMCJ10-E3/57T in bi-directional configurations risks forward conduction and failure.
