Product details
Overview
SMCJ13AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 13 V standoff voltage (VWM), 21.5 V maximum clamping voltage (VC) at 69.8 A peak pulse current (IPPM), and 1500 W peak pulse power (10/1000 µs waveform), commonly deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the SMCJ13AHE3_A/H datasheet, SMCJ13AHE3_A/H pinout, SMCJ13AHE3_A/H application, or SMCJ13AHE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, low incremental surge resistance, glass-passivated junction, and compatibility with automated SMT assembly on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below 13 V and rapidly transitions to low-impedance conduction above its 14.4–15.9 V breakdown range (VBR at 1.0 mA). Its response time is sub-nanosecond, enabling suppression of fast transients such as ESD (IEC 61000-4-2) and load dump spikes.
The device uses a planar silicon junction with glass passivation for stable leakage performance (<1.0 µA at VWM) and thermal stability up to 150 °C junction temperature. Its SMC package provides 75 °C/W junction-to-ambient thermal resistance under standard mounting conditions.

Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump transients (ISO 7637-2 Pulse 5a) and jump-start surges. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between power input and ground, absorbing >100 V spikes within nanoseconds. Use Value: Limits voltage seen by downstream DC/DC converters and microcontrollers to ≤21.5 V, preventing latch-up or gate oxide damage. | Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loop) from ESD and inductive switching noise in factory automation PLCs. IC Role / Device Role / Timing Role: Low-capacitance TVS connected across signal and return, shunting transients before reaching precision ADC or op-amp inputs. Use Value: Maintains signal integrity with <1.0 µA leakage at 13 V, avoiding offset errors while clamping ±30 kV contact ESD per IEC 61000-4-2. |
| Consumer Power Adapter Input Stage | Telecom DC Power Feeds |
Use Scenario: Secondary-side overvoltage protection in universal-input AC/DC adapters supplying 12 V to USB-C PD controllers. IC Role / Device Role / Timing Role: Standoff-rated TVS on regulated DC output rail, activated only during fault conditions like feedback loop failure. Use Value: Prevents catastrophic failure of downstream USB-PD ICs by clamping to 21.5 V before internal FETs exceed VDS rating. | Use Scenario: Surge protection on -48 V telecom power distribution boards exposed to lightning-induced surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Unidirectional TVS referenced to negative rail, conducting positive transients to ground while blocking normal -48 V bias. Use Value: Enables compliance with GR-1089-CORE Level 4 (4 kV/2 Ω) without derating due to its 1500 W rating and low Rsurge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What is the clamping voltage of SMCJ13AHE3_A/H at its rated peak pulse current?
The SMCJ13AHE3_A/H has a maximum clamping voltage (VC) of 21.5 V when subjected to its rated peak pulse current of 69.8 A using the standardized 10/1000 µs waveform. This value is measured under defined test conditions per ANSI/IEEE C62.35 and ensures predictable protection behavior for downstream components rated for ≤24 V operation. The SMCJ13AHE3_A/H maintains this clamping performance across its full operating temperature range.
Is SMCJ13AHE3_A/H qualified for automotive use?
Yes, SMCJ13AHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in the SMCJ5.0A–SMCJ188CA datasheet (Document Number 88394, Revision 09-Jan-2024). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD, making the SMCJ13AHE3_A/H suitable for engine control units, body electronics, and ADAS power domains where automotive-grade reliability is mandatory.
What is the standoff voltage and breakdown range for SMCJ13AHE3_A/H?
The SMCJ13AHE3_A/H has a standoff voltage (VWM) of 13 V and a guaranteed breakdown voltage (VBR) range of 14.4 V to 15.9 V at a test current of 1.0 mA. This 1.5 V window ensures reliable non-conduction during normal 12 V system operation while guaranteeing rapid avalanche onset during overvoltage events. The SMCJ13AHE3_A/H achieves this performance via a precisely doped planar silicon junction with glass passivation.
Does SMCJ13AHE3_A/H have a bidirectional variant?
Yes-the bidirectional counterpart is SMCJ13CAHE3_A/H, which shares identical electrical ratings (VWM = 13 V, VC = 21.5 V, PPPM = 1500 W) but provides symmetrical clamping for both polarities. Unlike the unidirectional SMCJ13AHE3_A/H, the SMCJ13CAHE3_A/H has no polarity marking and is used where voltage transients may reverse direction, such as on AC-coupled communication lines or floating sensor outputs. Both variants use the same SMC (DO-214AB) package.
What is the thermal resistance and maximum junction temperature of SMCJ13AHE3_A/H?
The SMCJ13AHE3_A/H 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 pads, and a maximum junction temperature (TJ) of +150 °C. These values define its safe operating area under continuous power dissipation and pulsed surge conditions. The SMCJ13AHE3_A/H must be routed with adequate copper pour to maintain TJ < 150 °C during repetitive transient events.
