Overview
SMCJ100AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients up to 162 V at 9.3 A peak pulse current (10/1000 µs), with 100 V standoff voltage and 1500 W peak pulse power rating. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics against inductive switching surges.
For engineers reviewing the SMCJ100AHE3_A/H datasheet, SMCJ100AHE3_A/H pinout, SMCJ100AHE3_A/H application, or SMCJ100AHE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, 111–123 V breakdown voltage range at 1 mA test current, low 0.107 %/°C temperature coefficient of VBR, and compatibility with automated SMT placement on standard 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-banded polarity, leveraging glass-passivated junction technology for stable surge response. Its 1500 W peak pulse power rating is specified under standardized 10/1000 µs waveform conditions, and thermal performance is defined by RθJA = 75 °C/W and RθJL = 15 °C/W.
The device meets MSL Level 1 per J-STD-020 with 260 °C reflow peak, features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and is qualified to AEC-Q101 for automotive use - confirmed by the "HE3" suffix and "_A/H" tape-and-reel packaging code.

| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., <1 ns rise time), improving protection margin |
Applications
| Automotive Power Distribution | Industrial Motor Drive Inputs |
|---|---|
|
Use Scenario: Protection of 12 V/24 V battery-fed ECUs against load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed across input rails to clamp transients before they reach DC-DC converters and microcontrollers. Use Value: Withstands 1500 W surges while limiting clamped voltage to 162 V - well below typical 200 V input stage ratings of automotive PMICs. |
Use Scenario: Safeguarding gate drivers and current-sense amplifiers in variable-frequency drives exposed to IGBT switching noise. IC Role / Device Role / Timing Role: Mounted at motor controller input terminals to suppress coupled transients from adjacent power stages. Use Value: Fast response time and low VC ensure sensitive analog front-ends remain within safe operating area during repetitive 10/1000 µs surges. |
| Telecom Power Supply Inputs | Automotive Sensor Signal Lines |
|
Use Scenario: Input-stage protection for PoE-powered network switches subjected to lightning-induced surges on Ethernet lines. IC Role / Device Role / Timing Role: Primary TVS on 48 V DC input rail, coordinated with upstream MOVs and downstream filtering. Use Value: 100 V VWM provides adequate margin above nominal 48 V, while 162 V VC avoids tripping downstream overvoltage protection. |
Use Scenario: ESD and surge protection for LIN/CAN sensor nodes (e.g., temperature, pressure) in engine compartments. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS placed directly at connector entry point before signal conditioning circuitry. Use Value: AEC-Q101 qualification and -55 °C to +150 °C operation ensure reliability across full automotive temperature range without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100AHE3/A | Lower PPPM (400 W), smaller SMA package (DO-214AC), same VWM/VBR range | Not suitable for high-energy transients; limited to consumer-grade or low-risk industrial interfaces | Select when board space is constrained and surge threat level is ≤ Class 2 per IEC 61000-4-5 |
| SMCJ100CAHE3_A/H | Bidirectional variant; identical VWM, VBR, and PPPM but symmetrical clamping in both polarities | Required for AC-coupled or floating signal lines where polarity reversal may occur (e.g., RS-485, audio) | Choose only if bidirectional protection is mandated; unidirectional SMCJ100AHE3_A/H offers lower cost and simpler layout |
Compared with SMAJ100AHE3/A and SMCJ100CAHE3_A/H, the SMCJ100AHE3_A/H delivers optimal balance of high-energy clamping (1500 W), AEC-Q101 compliance, and SMC package robustness - making it the preferred choice for automotive power inputs and industrial DC bus protection where single-polarity transients dominate.

FAQ
What is the breakdown voltage range of the SMCJ100AHE3_A/H?
The SMCJ100AHE3_A/H has a guaranteed breakdown voltage (VBR) range of 111 V to 123 V at a test current of 1 mA, as specified in the Vishay datasheet document 88394. This range ensures reliable and repeatable clamping behavior across manufacturing lots and temperature extremes. The SMCJ100AHE3_A/H maintains this specification under standard test conditions and is validated for use in automotive applications where voltage tolerance stability is critical.
Is the SMCJ100AHE3_A/H suitable for automotive applications?
Yes, the SMCJ100AHE3_A/H is explicitly AEC-Q101 qualified, as indicated by the "HE3" suffix and confirmed in Vishay's ordering information and mechanical data tables. It is rated for operation from -55 °C to +150 °C and meets MSL Level 1 for reflow compatibility. The SMCJ100AHE3_A/H is widely deployed in automotive power distribution modules, body control units, and sensor interface circuits where certified reliability is mandatory.
What does the "_A/H" suffix mean in SMCJ100AHE3_A/H?
The "_A/H" suffix in SMCJ100AHE3_A/H denotes packaging configuration: "A" indicates the revision code (per Vishay's documentation), and "H" specifies the preferred package code for 7-inch diameter plastic tape-and-reel delivery with 850 units per reel. This matches the ordering example shown in the datasheet's "ORDERING INFORMATION" section and confirms the part is supplied in standard SMT-compatible format ready for high-volume placement.
How does the clamping voltage of SMCJ100AHE3_A/H compare to its standoff voltage?
The SMCJ100AHE3_A/H has a standoff voltage (VWM) of 100 V and a maximum clamping voltage (VC) of 162 V at 9.3 A peak pulse current. This 62 V differential provides a defined protection margin - ensuring that downstream components experience no more than 162 V during worst-case transients while remaining fully functional below 100 V during normal operation. The SMCJ100AHE3_A/H achieves this with low incremental surge resistance and fast response, critical for safeguarding modern 100 V-rated power ICs.
Can SMCJ100AHE3_A/H be used in place of a bidirectional TVS like SMCJ100CAHE3_A/H?
No - the SMCJ100AHE3_A/H is unidirectional and must not replace a bidirectional device unless circuit polarity is strictly controlled. The SMCJ100CAHE3_A/H clamps in both directions and is required for AC-coupled or floating lines (e.g., RS-485, antenna feeds). Using the unidirectional SMCJ100AHE3_A/H in such applications risks catastrophic failure during reverse-polarity transients. Always verify signal polarity and transient direction before selecting between SMCJ100AHE3_A/H and its bidirectional counterpart.
