Product details
Overview
SMCJ10CAHE3_A/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 10 V standoff voltage (VWM), 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 - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMCJ10CAHE3_A/H datasheet, SMCJ10CAHE3_A/H pinout, SMCJ10CAHE3_A/H application, or SMCJ10CAHE3_A/H equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, low thermal resistance (RθJL = 15 °C/W), and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within picoseconds to transients induced by inductive switching or ESD events. Its glass-passivated junction ensures stable breakdown behavior across -55 °C to +150 °C operating range, and its bidirectional architecture provides symmetrical clamping in both polarities without polarity marking.
The device meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), supports 200 A non-repetitive forward surge (IFSM), and delivers <1.0 µA reverse leakage at VWM - enabling reliable protection in high-reliability automotive and industrial systems where unidirectional alternatives would require external polarity management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below system rail voltage. |
| VC @ IPPM | 17.0 V - clamped voltage during 88.2 A 10/1000 µs surge; determines maximum stress imposed on protected ICs. |
| PPPM | 1500 W - peak pulse power handling capability; enables suppression of high-energy transients like ISO 7637-2 Pulse 1/2a/5a. |
| TJ max. | +150 °C - maximum junction temperature; supports under-hood automotive deployment with minimal derating. |
| RθJL | 15 °C/W - low junction-to-lead thermal resistance; allows effective heat dissipation through PCB copper without heatsink. |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional - no polarity marking; terminals are matte tin-plated leads solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode / Anode | Common terminal pair | Bidirectional conduction path - either terminal serves as cathode or anode depending on transient polarity; no band marking required. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR min/max (11.1 V / 12.3 V) and VC in both directions - eliminates need for polarity-aware layout or external diode pairing. |
| AEC-Q101 qualification | Validated for automotive applications including engine control, ADAS sensors, and infotainment power rails - reduces qualification effort for Tier 1 suppliers. |
| Low incremental surge resistance | Enables tight VC-VWM margin (7.0 V differential) - minimizes voltage overshoot during fast transients while maintaining robust energy absorption. |
| MSL Level 1 rating | Compatible with standard lead-free reflow profiles up to 260 °C peak - supports high-yield automated assembly without moisture sensitivity concerns. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-supplied microcontrollers and CAN transceivers from load dump and alternator ripple. IC Role / Device Role / Timing Role: Shunt clamping device placed between VBAT and GND, triggered only during overvoltage events >10 V. Use Value: Clamps transients to ≤17.0 V, preventing latch-up or gate oxide damage in downstream 20 V-rated ICs while surviving repeated 1500 W surges. | Use Scenario: Safeguarding analog front-end inputs of pressure/temperature sensors connected to long harnesses in factory automation. IC Role / Device Role / Timing Role: Bidirectional transient suppressor on differential signal pairs (e.g., RS-485, analog sensor outputs) referenced to local ground. Use Value: Symmetric clamping prevents signal inversion or DC offset shift during ESD or inductive kick events, preserving measurement integrity. |
| Consumer Device USB Port Protection | Telecom Base Station DC Power Input |
Use Scenario: Adding secondary overvoltage defense on USB VBUS line after primary fuse and upstream TVS in portable docking stations. IC Role / Device Role / Timing Role: Secondary shunt clamp activated when upstream protection fails or during slow-rising surges exceeding 10 V threshold. Use Value: Withstands 88.2 A peak current and maintains <1.0 µA leakage at 10 V - avoids standby current drain while ensuring fail-safe shutdown. | Use Scenario: Protecting -48 V telecom rectifier outputs against lightning-induced surges entering via outdoor cabling. IC Role / Device Role / Timing Role: Bidirectional clamp installed across input bus to chassis ground, absorbing common-mode transients coupled onto DC feed lines. Use Value: 1500 W PPPM rating and 15 °C/W RθJL enable sustained operation in sealed enclosures without forced airflow or heatsinking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CAHE3_A/H | Lower PPPM (400 W), smaller SMA package (DO-214AC), same VWM/VC specs. | Not suitable for ISO 7637-2 Pulse 5a or high-energy load dump; limited to low-power signal lines. | Select when board space is constrained and surge energy is ≤400 W. |
| SMCJ10CAHM3_A/H | Halogen-free variant; identical electrical and thermal specs; same AEC-Q101 qualification. | No functional difference - used where RoHS-compliant halogen-free materials are mandated by OEM specification. | Select when halogen-free compliance is required without compromising performance or qualification status. |
Compared with SMCJ10CAHE3_A/H, SMAJ10CAHE3_A/H trades surge capacity for footprint reduction, while SMCJ10CAHM3_A/H offers identical protection with halogen-free construction - enabling direct material substitution where environmental compliance drives selection.

FAQ
What does the "CA" suffix indicate in SMCJ10CAHE3_A/H?
The "CA" suffix in SMCJ10CAHE3_A/H denotes a bidirectional configuration - meaning the device provides symmetrical transient voltage suppression in both polarities, with identical breakdown and clamping characteristics regardless of voltage polarity applied across its terminals. This eliminates the need for polarity-aware placement and simplifies design for AC-coupled or floating signal lines.
Is SMCJ10CAHE3_A/H qualified for automotive use?
Yes, SMCJ10CAHE3_A/H is AEC-Q101 qualified, verified per the full stress test schedule including temperature cycling, high-temperature reverse bias, and ESD testing. The "HE3" suffix explicitly indicates RoHS-compliant and AEC-Q101-qualified construction, making it suitable for under-hood and chassis-mounted automotive applications such as body control modules and ADAS sensor nodes.
What is the clamping voltage of SMCJ10CAHE3_A/H at its rated peak pulse current?
The clamping voltage (VC) of SMCJ10CAHE3_A/H is 17.0 V when subjected to its rated peak pulse current (IPPM) of 88.2 A under the standard 10/1000 µs waveform. This value is measured across the device terminals during surge conduction and defines the maximum voltage seen by downstream circuitry during transient events.
How does the SMC (DO-214AB) package of SMCJ10CAHE3_A/H impact thermal performance?
The SMC (DO-214AB) package of SMCJ10CAHE3_A/H provides a typical junction-to-lead thermal resistance (RθJL) of 15 °C/W, enabling efficient heat transfer to PCB copper pads. When mounted on 8.0 mm × 8.0 mm copper pads per Vishay's recommended layout, it sustains full 1500 W pulse power without thermal runaway - critical for high-reliability automotive and industrial deployments.
Can SMCJ10CAHE3_A/H replace unidirectional TVS diodes in existing designs?
SMCJ10CAHE3_A/H can replace unidirectional TVS diodes only if the circuit topology supports bidirectional clamping and polarity-insensitive placement - for example, across floating signal pairs or symmetric power buses. It should not replace unidirectional devices in circuits relying on cathode-anode directionality for DC blocking or rectification, as SMCJ10CAHE3_A/H lacks polarity marking and conducts equally in both directions.
