Product details
Overview
SMCJ10AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, with 10 V standoff 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) rating for 10/1000 μs transients. It protects MOSFETs, ICs, and sensor signal lines against inductive switching surges and ESD in automotive and industrial power rails.
For engineers reviewing the SMCJ10AHE3_A/H datasheet, SMCJ10AHE3_A/H pinout, SMCJ10AHE3_A/H application, or SMCJ10AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 1500 W surge capability, 17.0 V clamping performance at rated current, and RoHS-compliant matte tin-plated leads suitable for automated SMT assembly.
Technical Context
The SMCJ10AHE3_A/H uses a glass-passivated silicon junction to achieve fast response time (<1 ps) and low incremental surge resistance, enabling effective clamping of fast-rising transients such as ISO 7637-2 pulses and IEC 61000-4-5 surges. Its thermal resistance (RθJA = 75 °C/W) and junction temperature range (–55 to +150 °C) support reliable operation in under-hood automotive environments.
Designed for unidirectional protection only, it features cathode-band polarity marking, meets MSL Level 1 per J-STD-020 (260 °C reflow peak), and delivers stable clamping across temperature due to a +0.078 %/°C VBR temperature coefficient - critical for maintaining protection margins over wide ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple transients per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges above 17.0 V. Use Value: Prevents latch-up or permanent damage to microcontrollers and CAN transceivers by limiting transient voltage to ≤17.0 V at 88.2 A. | Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loop) from ESD and cable discharge events in factory automation sensors. IC Role / Device Role / Timing Role: TVS connected in parallel with signal line and ground to shunt fast transients before reaching ADC input or op-amp buffer. Use Value: Maintains signal fidelity with only 5.0 μA leakage at 10 V, avoiding offset errors or gain drift in precision measurement circuits. |
| DC-DC Converter Input Protection | Motor Drive Gate Driver Protection |
Use Scenario: Shielding buck converter inputs from back-EMF spikes generated by relay switching or solenoid de-energization. IC Role / Device Role / Timing Role: Unidirectional TVS installed upstream of input capacitor to absorb 1500 W surges within 10/1000 μs profile. Use Value: Eliminates need for oversized input capacitors or additional RC snubbers by providing deterministic clamping at 17.0 V. | Use Scenario: Protecting high-side and low-side gate drivers (e.g., IR2110) from Miller-induced voltage spikes during MOSFET switching transitions. IC Role / Device Role / Timing Role: TVS placed between gate and source terminals to clamp dv/dt-induced overshoot exceeding VGS(max). Use Value: Prevents false turn-on and gate oxide breakdown with sub-nanosecond response and 17.0 V clamping ceiling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC10A-TB-E3 | Same VWM (10 V), lower PPPM (600 W), smaller SMA package (DO-214AC) | Limited to lower-energy surges; unsuitable for ISO 7637-2 load dump | Select only for space-constrained consumer electronics with <600 W threat profiles |
| 1.5KE10A | Through-hole TO-218 package, identical VWM/VBR/VC specs, same 1500 W rating | Requires wave soldering or hand assembly; incompatible with fully SMT production | Choose for legacy board redesigns where SMC footprint change is not feasible |
Compared with SAC10A-TB-E3 and 1.5KE10A, the SMCJ10AHE3_A/H uniquely combines AEC-Q101 qualification, SMC surface-mount compatibility, and full 1500 W surge handling - making it the preferred choice for new automotive and industrial SMT designs requiring validated reliability and high-power transient immunity.

FAQ
What is the clamping voltage of the SMCJ10AHE3_A/H at its rated peak pulse current?
The SMCJ10AHE3_A/H has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 88.2 A under the standard 10/1000 μs waveform. This value is measured with device mounted on 8.0 mm × 8.0 mm copper pads per JEDEC guidelines and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCJ10AHE3_A/H maintains this clamping performance across its operational temperature range.
Is the SMCJ10AHE3_A/H qualified for automotive applications?
Yes, the SMCJ10AHE3_A/H carries AEC-Q101 qualification, verified through stress testing including high-temperature reverse bias (HTRB), temperature cycling, and surge endurance. Its HE3 suffix explicitly denotes RoHS-compliant and AEC-Q101-qualified construction, making the SMCJ10AHE3_A/H suitable for use in engine control units, body electronics, and ADAS modules where automotive-grade reliability is required.
What does the "_A/H" suffix indicate in SMCJ10AHE3_A/H?
The "_A/H" suffix in SMCJ10AHE3_A/H specifies packaging configuration: "A" denotes the revision code per Vishay's internal documentation, and "H" indicates the preferred package code for 7-inch diameter plastic tape-and-reel delivery with 850 units per reel. This matches the ordering information in Document Number 88394 and confirms the SMCJ10AHE3_A/H is supplied in standard SMT-compatible format ready for pick-and-place assembly.
How does the SMCJ10AHE3_A/H compare to bidirectional TVS diodes like SMCJ10CA?
The SMCJ10AHE3_A/H is unidirectional and intended for DC line protection where polarity is fixed, whereas SMCJ10CA is bidirectional and suited for AC or floating signal lines. The SMCJ10AHE3_A/H exhibits forward conduction behavior below VBR (VF = 3.5 V at 100 A), while SMCJ10CA clamps symmetrically in both directions. For 12 V automotive power rails, the SMCJ10AHE3_A/H provides lower leakage and better thermal margin than its bidirectional counterpart.
What is the maximum junction temperature rating for the SMCJ10AHE3_A/H?
The SMCJ10AHE3_A/H has a maximum junction temperature (TJ max) of +150 °C, as specified in the Thermal Characteristics table of Vishay Document Number 88394. This rating enables reliable operation in under-hood automotive environments and high-power industrial enclosures. Derating curves in Figure 2 show that the device retains ≥80 % of its 1500 W peak pulse power capability up to TJ = 100 °C when properly mounted on recommended copper pads.
