Product details
Overview
SMCJ10CHE3/57T from Vishay General Semiconductor is a bi-directional 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), 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 automotive and industrial power rail and signal line protection.
For engineers reviewing the SMCJ10CHE3/57T datasheet, SMCJ10CHE3/57T pinout, SMCJ10CHE3/57T application, or SMCJ10CHE3/57T equivalent, key selection criteria include its AEC-Q101 qualification, bi-directional symmetry, low clamping ratio (VC/VWM = 1.7), and compatibility with automated SMT assembly on standard 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ10CHE3/57T operates as a voltage-clamping device that remains high-impedance below 10 V (VWM) and rapidly transitions to low-impedance conduction above its breakdown threshold (VBR min = 11.1 V, max = 12.3 V at 1.0 mA). Its bi-directional architecture ensures symmetrical clamping in both polarities without polarity marking, making it suitable for AC-coupled or floating signal paths.
It delivers 1500 W surge handling per IEC 61000-4-5 (10/1000 µs) with <1 ps response time and low incremental surge resistance, supported by glass-passivated junction and MSL Level 1 moisture sensitivity rating (peak reflow 260 °C). Thermal resistance is RθJA = 75 °C/W (on recommended pad layout) and RθJL = 15 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for protected circuit. |
| VBR (min/max) | 11.1 V / 12.3 V at 1.0 mA - Breakdown voltage range where TVS initiates conduction; tight tolerance enables predictable trigger behavior. |
| VC @ IPPM | 17.0 V at 88.2 A - Clamped voltage during full 1500 W surge; limits downstream voltage stress to ≤17.0 V under worst-case transients. |
| PPPM | 1500 W - Peak pulse power capability with 10/1000 µs waveform; meets IEC 61000-4-5 Level 4 surge immunity requirements. |
| TJ max. | +150 °C - Maximum junction temperature; supports operation in under-hood automotive environments and industrial enclosures. |
| Package | DO-214AB (SMCJ) - Surface-mount, low-profile package with matte tin-plated leads; compatible with J-STD-002 solderability and JESD 22-B102. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package
DO-214AB (SMCJ) package: surface-mount, molded plastic case with J-bend leads; no polarity marking for bi-directional configuration; terminals are matte tin-plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional transient conduction path | No functional distinction between terminals; either lead serves as input/output for bidirectional surge suppression. |
| Case (body) | Thermal and mechanical interface | Non-electrical; provides thermal path to PCB copper pads (recommended 8.0 mm × 8.0 mm per terminal). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |
| Bi-directional symmetry | Identical VBR, VC, and IPPM in both directions - eliminates polarity concerns in AC or differential signal lines. |
| Low clamping ratio (VC/VWM) | 1.7 - Minimizes overvoltage overshoot during surge events, enhancing protection margin for 12 V systems. |
| MSL Level 1 rating | Supports lead-free reflow up to 260 °C peak without preconditioning - simplifies manufacturing flow. |
| Glass-passivated junction | Ensures stable leakage performance (<1.0 µA at VWM) and long-term reliability under thermal cycling. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-supplied ECUs against load dump (ISO 16750-2) and alternator switching transients. IC Role / Device Role / Timing Role: Primary clamping element placed directly at power entry point before DC/DC converters or LDOs. Use Value: Limits transient voltage to ≤17.0 V, preventing damage to downstream 24 V-tolerant ICs while sustaining 1500 W surges. |
Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) connected to microcontrollers in factory automation PLCs. IC Role / Device Role / Timing Role: Bidirectional shunt protector on differential or single-ended signal lines exposed to ESD and inductive kickback. Use Value: Clamps ±17.0 V transients within nanoseconds, preserving signal integrity and avoiding false triggers in 10-bit ADC inputs. |

Use Scenario: Adding secondary-level ESD protection on USB 2.0 or LVDS display interface traces in laptops and monitors. IC Role / Device Role / Timing Role: Low-capacitance shunt device located near connector to divert >8 kV HBM ESD pulses before reaching PHY IC. Use Value: Delivers 1500 W surge handling without degrading 480 Mbps data eye due to minimal parasitic capacitance and fast response. |
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 ISO 16750-2 load dump | Select when board space is constrained and surge energy is ≤600 W. |
| SMCJ10AHE3/57T | Uni-directional version; identical VWM, VBR, VC, and PPPM but marked cathode band | Requires correct polarity placement; not interchangeable in AC or floating circuits | Choose only for DC-biased rails where unidirectional clamping suffices. |
Compared with SAC10CA and SMCJ10AHE3/57T, the SMCJ10CHE3/57T uniquely combines AEC-Q101 qualification, bi-directional symmetry, and full 1500 W surge rating in DO-214AB - making it the preferred choice for automotive and industrial applications demanding robust, polarity-agnostic protection.

FAQ
What is the clamping voltage of SMCJ10CHE3/57T under maximum surge conditions?
The SMCJ10CHE3/57T has a maximum clamping voltage (VC) of 17.0 V at 88.2 A peak pulse current (IPPM), measured with a 10/1000 µs waveform. This value ensures protected circuits experience no more than 17.0 V during full-rated 1500 W transients, providing critical headroom for 12 V system components.
Is SMCJ10CHE3/57T suitable for automotive applications?
Yes, the SMCJ10CHE3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including engine control modules, body electronics, and ADAS sensor interfaces. Its DO-214AB package, 150 °C max junction temperature, and load-dump survivability make it compliant with ISO 16750-2 requirements.
How does the bi-directional design of SMCJ10CHE3/57T affect PCB layout?
The SMCJ10CHE3/57T has no polarity marking and identical electrical behavior in both directions, eliminating orientation constraints during placement. This simplifies layout for AC-coupled lines, differential pairs, or floating grounds - no silkscreen polarity indicator or footprint asymmetry is needed.
What is the thermal resistance of SMCJ10CHE3/57T, and how does it impact derating?
The SMCJ10CHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. At 100 °C ambient, its power dissipation must be derated to ~3.3 W continuous to maintain TJ ≤ 150 °C - consistent with its 6.5 W rating at TA = 50 °C.
Does SMCJ10CHE3/57T meet RoHS and lead-free assembly requirements?
Yes, the "HE3" suffix denotes RoHS-compliant, matte tin-plated leads qualified for lead-free reflow up to 260 °C peak temperature (MSL Level 1). The device conforms to JEDEC JS709A halogen-free standards and passes JESD 201 Class 2 whisker testing.
