Product details
Overview
1.5SMC100AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, rated for 100 V standoff voltage (VWM), 105 V maximum breakdown voltage (VBR), and 1500 W peak pulse power (10/1000 μs). It clamps transients to 137 V at 10.9 A peak pulse current and is halogen-free, RoHS-compliant, and AEC-Q101 qualified for automotive use.
For engineers reviewing the 1.5SMC100AHM3_A/I datasheet, 1.5SMC100AHM3_A/I pinout, 1.5SMC100AHM3_A/I application, or 1.5SMC100AHM3_A/I equivalent, key selection criteria include its 137 V clamping voltage at 10.9 A, -65 °C to +150 °C operating temperature range, 1.0 μA max reverse leakage at 85.5 V, and suitability for protecting automotive sensor signal lines, DC power rails, and MOSFET gate drivers against lightning and inductive switching surges.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping protection device that enters avalanche conduction when reverse voltage exceeds its 95–105 V breakdown range. Its glass-passivated junction ensures stable performance under repetitive surge conditions with 0.01 % duty cycle.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it delivers 1500 W peak pulse power handling and exhibits low incremental surge resistance-critical for limiting let-through energy during fast transients like ESD or load dump events in automotive ECUs.

Use Scenario: Adding secondary overvoltage protection on CAN_H/CAN_L lines in gateway ECUs where primary protection resides upstream. IC Role / Device Role / Timing Role: Unidirectional TVS on each line referenced to ground, complementing bidirectional TVS or common-mode chokes. Use Value: Limits differential and common-mode surge voltages to <137 V, preserving CAN transceiver functionality per ISO 11898-2 immunity targets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100AHE3_A/H | Same 100 V VWM, but SMB package (DO-214AA); 600 W PPPM rating vs. 1500 W | Limited to lower-energy transients; unsuitable for load dump or high-current inductive spikes | Select when board space is constrained and surge energy is ≤600 W (e.g., interior non-critical modules) |
| 1.5KE100A | Through-hole TO-204AE (DO-41); identical 100 V VWM and 1500 W rating, but no AEC-Q101 qualification | Not approved for automotive production; used in industrial or legacy designs where reflow compatibility is not required | Choose only for cost-sensitive non-automotive applications where SMT assembly is not mandatory |
Compared with SMBJ100AHE3_A/H and 1.5KE100A, the 1.5SMC100AHM3_A/I uniquely combines AEC-Q101 qualification, 1500 W SMT capability, and halogen-free compliance-making it the only drop-in solution for new automotive designs requiring both high surge rating and production-grade reliability.

FAQ
What is the clamping voltage of the 1.5SMC100AHM3_A/I under a 10/1000 μs surge?
The 1.5SMC100AHM3_A/I clamps to a maximum of 137 V at 10.9 A peak pulse current when subjected to a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 8.0 mm × 8.0 mm copper pads) and defines the upper voltage limit imposed on protected circuits during surge events. The 137 V clamping level ensures compatibility with 12 V automotive systems and safeguards 3.3 V/5 V logic interfaces downstream.
Is the 1.5SMC100AHM3_A/I suitable for automotive applications?
Yes, the 1.5SMC100AHM3_A/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction validated for automotive use. It meets requirements for temperature cycling, high-temperature reverse bias, and mechanical shock-making it appropriate for engine control, body electronics, and ADAS sensor modules. Its 1500 W surge rating aligns with ISO 16750-2 load-dump immunity testing.
What does the "HM3" suffix mean in 1.5SMC100AHM3_A/I?
The "HM3" suffix in 1.5SMC100AHM3_A/I denotes halogen-free, RoHS-compliant, and AEC-Q101 qualified construction. The "H" indicates 7-inch tape-and-reel packaging (850 units/reel), while "I" specifies 13-inch tape-and-reel (3500 units/reel). This distinguishes it from commercial-grade M3 or HE3 variants and confirms compliance with automotive supply chain material and reliability standards.
How does the 1.5SMC100AHM3_A/I differ from bidirectional TVS diodes like 1.5SMC100CA?
The 1.5SMC100AHM3_A/I is unidirectional and features a cathode band for polarity-sensitive placement, optimized for DC rail-to-ground protection. In contrast, 1.5SMC100CA is bidirectional with symmetrical clamping in both directions-used for AC lines or differential buses like RS-485. The 1.5SMC100AHM3_A/I offers tighter leakage control (<1.0 μA) and is AEC-Q101 qualified, whereas 1.5SMC100CA lacks automotive qualification unless specified with HE3/HM3 suffixes.
What is the thermal resistance of the 1.5SMC100AHM3_A/I?
The 1.5SMC100AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended pad layout, and a junction-to-leads resistance (RθJL) of 15 °C/W. These values enable effective heat dissipation during repetitive surge events and support operation up to +150 °C junction temperature-critical for under-hood automotive placement where ambient temperatures exceed 105 °C.
