Product details
Overview
1.5SMC100AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power rails and signal lines. It features a 100 V standoff voltage (VWM), 137 V maximum clamping voltage at 10.9 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces, industrial motor control inputs, and telecom power supply surge protection.
For engineers reviewing the 1.5SMC100AHE3_A/H datasheet, 1.5SMC100AHE3_A/H pinout, 1.5SMC100AHE3_A/H application, or 1.5SMC100AHE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, DO-214AB (SMC) package thermal performance, unidirectional polarity marking, and verified clamping behavior under repetitive transients per IEC 61000-4-5.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds its breakdown threshold (95–105 V at 1 mA), it avalanches to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable leakage (<1 µA at 85.5 V) and fast response time (<1 ns), critical for protecting MOSFET gates and microcontroller I/O pins.
Thermally, it uses the SMC (DO-214AB) package with RθJA = 75 °C/W and RθJL = 15 °C/W, enabling reliable operation up to 150 °C junction temperature. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification - validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing.

Use Scenario: Safeguarding PLC digital input modules connected to 24 V DC field wiring exposed to inductive kickback from solenoids and contactors. IC Role / Device Role / Timing Role: Unidirectional TVS mounted at connector entry point, absorbing repetitive 600 W switching surges. Use Value: Maintains input logic integrity by holding voltage below 137 V during 10.9 A transients, eliminating false triggering and latch-up in optocouplers. |
| Telecom Power Supply Output | Automotive Sensor Signal Lines |
Use Scenario: Secondary-side overvoltage suppression on 48 V telecom rectifier outputs feeding PoE injectors and base station radios. IC Role / Device Role / Timing Role: Standoff-rated TVS parallel to output capacitor, activated only during fault conditions exceeding 85.5 V. Use Value: Prevents catastrophic failure of downstream DC-DC converters by clamping sustained overvoltages to 137 V with <1 µA leakage at nominal 48 V. |
Use Scenario: Protecting LIN bus or analog sensor outputs (e.g., pressure, temperature) in vehicle cabin modules from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS placed at connector, referenced to local ground plane. Use Value: Clamps ±8 kV contact ESD (IEC 61000-4-2) to <137 V while adding <0.5 pF parasitic capacitance - preserving signal rise time and noise immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A-E3/52 | Lower peak power (600 W), same VWM/VC, SMB (DO-214AA) package - 30% smaller footprint, higher RθJA (100 °C/W). | Suitable for space-constrained consumer electronics but not automotive load dump due to lower PPPM. | Select when board area is critical and surge energy is limited to ≤600 W (e.g., USB power delivery ports). |
| 1.5KE100A | Through-hole TO-204AE (DO-201AE) package, identical electrical specs, no AEC-Q101 qualification, higher mounting inductance. | Used in legacy industrial power supplies where manual assembly and high-reliability through-hole mounting are preferred. | Choose only for non-automotive, non-SMT designs requiring proven field history and easier prototyping. |
Compared with 1.5SMC100AHE3_A/H, SMBJ100A-E3/52 trades surge robustness for compactness, while 1.5KE100A sacrifices AEC-Q101 validation and SMT compatibility for mechanical ruggedness - making 1.5SMC100AHE3_A/H the sole choice for new automotive SMT designs requiring 1500 W clamping and production-grade qualification.

FAQ
What is the clamping voltage of the 1.5SMC100AHE3_A/H under a 10/1000 µs surge?
The 1.5SMC100AHE3_A/H clamps to a maximum of 137 V when subjected to a 10.9 A peak pulse current with a 10/1000 µs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 8 mm × 8 mm copper pads) and defines the upper voltage limit imposed on protected circuitry during surge events. The 1.5SMC100AHE3_A/H maintains this clamping performance across its full operational temperature range.
Is the 1.5SMC100AHE3_A/H suitable for automotive applications?
Yes, the 1.5SMC100AHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use via the "HE3" suffix. It has passed stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST), confirming suitability for engine control units, body electronics, and ADAS sensor modules. The 1.5SMC100AHE3_A/H meets ISO 16750-2 load dump requirements when properly laid out.
What does the "_A/H" suffix mean in 1.5SMC100AHE3_A/H?
The "_A/H" suffix in 1.5SMC100AHE3_A/H indicates packaging configuration: "A" denotes AEC-Q101 qualification level for the 6.8 V to 220 V voltage range, and "H" specifies 7-inch plastic tape-and-reel delivery with 850 units per reel. This ordering code ensures traceable, automotive-grade material with verified qualification status and standardized SMT handling - distinct from commercial-grade "E3" or halogen-free "HM3" variants.
How does the 1.5SMC100AHE3_A/H compare to bidirectional TVS diodes like 1.5SMC100CA?
The 1.5SMC100AHE3_A/H is unidirectional and optimized for DC power rail protection where polarity is fixed (e.g., 12 V battery lines), offering lower leakage (<1 µA at 85.5 V) and tighter VBR tolerance. In contrast, 1.5SMC100CA is bidirectional and used for AC or differential signal lines (e.g., RS-485), with symmetrical clamping in both directions but higher leakage. The 1.5SMC100AHE3_A/H cannot replace 1.5SMC100CA in AC-coupled applications due to polarity dependence.
What PCB layout guidelines apply to the 1.5SMC100AHE3_A/H for optimal surge performance?
For optimal performance, route the 1.5SMC100AHE3_A/H with minimum-length, wide traces directly between the protected line and ground plane - avoiding vias or daisy-chained connections. Mount on 8 mm × 8 mm copper pads per terminal as specified in the Vishay datasheet (Document 88303), and ensure solid thermal connection to inner-layer ground planes. Keep the 1.5SMC100AHE3_A/H within 2 cm of the protected connector or IC pin to minimize inductance-induced voltage overshoot during fast transients.
