Product details
Overview
1.5SMC100CAHM3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 100 V standoff voltage (VWM), 114 V minimum breakdown voltage (VBR), 137 V maximum clamping voltage (VC) at 10.9 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the 1.5SMC100CAHM3_A/I datasheet, 1.5SMC100CAHM3_A/I pinout, 1.5SMC100CAHM3_A/I application, or 1.5SMC100CAHM3_A/I equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, SMC (DO-214AB) package thermal performance, and compliance with UL 497B for telecom surge protection.
Technical Context
This device operates as a voltage-clamped crowbar during transient overvoltage events, leveraging an avalanche breakdown mechanism to divert surge energy away from downstream circuitry. Its bidirectional structure enables symmetric clamping in both polarities without polarity-sensitive layout constraints.
Designed for repetitive surge handling up to 0.01% duty cycle, it sustains 1500 W peak pulse power under standardized 10/1000 μs waveform conditions when mounted on 8.0 mm × 8.0 mm copper pads. Junction temperature remains within safe limits (TJ max = 150 °C) due to low thermal resistance (RθJL = 15 °C/W) and MSL Level 1 moisture sensitivity rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 100 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 114–126 V at 1 mA - Guaranteed avalanche initiation range; ensures predictable turn-on during transients. |
| VC (Clamping) | 137 V at 10.9 A - Maximum voltage seen by protected circuit during full-rated surge; determines stress on downstream components. |
| PPPM | 1500 W - Peak pulse power dissipation capability with 10/1000 μs waveform; validates robustness against lightning-induced surges. |
| Package | SMC (DO-214AB) - Surface-mount package with 7.75 mm × 6.22 mm footprint and 2.62 mm height; optimized for automated placement and thermal pad coupling. |
| AEC-Q101 | Qualified - Certified for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing per JESD22 standards. |
| RoHS & Halogen-Free | Compliant - Meets EU RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21; suitable for green manufacturing. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge return path (bidirectional) | Provides symmetrical conduction path during positive or negative transients; connects to protected line or ground reference. |
| Cathode | Surge return path (bidirectional) | Electrically identical to Anode in CA-series devices; no functional distinction - both terminals serve as interchangeable surge shunt nodes. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns - reduces BOM count and layout complexity. |
| 1500 W peak pulse power | Handles IEC 61000-4-5 Level 4 surges (4 kV line-to-earth) in properly decoupled systems - meets industrial and automotive EMC requirements. |
| Low clamping ratio (VC/VBR ≈ 1.20) | Minimizes voltage overshoot during clamping - preserves margin for 12 V or 24 V rail-tolerant ICs such as CAN transceivers and ADC front-ends. |
| AEC-Q101 qualification | Validates suitability for under-hood and chassis-mounted applications where temperature cycling (-40 °C to +125 °C) and vibration endurance are critical. |
| MSL Level 1 rating | Allows unlimited floor life and reflow compatibility up to 260 °C peak - eliminates baking requirements and supports high-yield SMT assembly. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Lower peak pulse power (600 W), same VWM (100 V), SMB package (smaller footprint, higher RθJA = 90 °C/W) | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for automotive load dump or telecom primary protection | Select when board space is constrained and surge threat level is moderate - verify thermal derating at 125 °C ambient. |
| 1.5KE100CA | Higher VBR (117–130 V), same VC (137 V), axial DO-201 package (through-hole, no SMT compatibility) | Requires manual assembly or wave soldering; incompatible with automated SMT lines and high-density layouts | Choose only for legacy repair or prototyping where SMT is unavailable - not recommended for new designs targeting AEC-Q101 or IPC-A-610 compliance. |
Compared with SMBJ100CA and 1.5KE100CA, the 1.5SMC100CAHM3_A/I delivers superior surge robustness in a qualified SMT package, enabling automotive-grade reliability without layout or process compromises - making it optimal for volume production of certified industrial and automotive electronics.

FAQ
What is the clamping voltage of the 1.5SMC100CAHM3_A/I at its rated peak pulse current?
The 1.5SMC100CAHM3_A/I has a maximum clamping voltage (VC) of 137 V at 10.9 A peak pulse current (IPPM), measured under standard 10/1000 μs waveform conditions. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events. The 1.5SMC100CAHM3_A/I maintains this clamping performance due to its low dynamic impedance and optimized junction design.
Is the 1.5SMC100CAHM3_A/I suitable for automotive applications?
Yes, the 1.5SMC100CAHM3_A/I is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its qualification covers temperature cycling, mechanical shock, and humidity testing per JESD22 standards. The 1.5SMC100CAHM3_A/I also meets UL 497B for telecom protectors, supporting dual-use in vehicle telematics and infotainment systems.
What does the "HM3" suffix indicate in 1.5SMC100CAHM3_A/I?
The "HM3" suffix in 1.5SMC100CAHM3_A/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. The "H" indicates 7-inch tape-and-reel packaging (850 units per reel), while "I" specifies 13-inch tape-and-reel (3500 units per reel). This distinguishes it from commercial-grade "E3" or "M3" variants and confirms compliance with automotive environmental and reliability requirements.
How does the bidirectional configuration of the 1.5SMC100CAHM3_A/I affect PCB layout?
The 1.5SMC100CAHM3_A/I has no polarity marking and functions identically in both directions, eliminating orientation constraints during placement. This simplifies PCB layout for AC-coupled lines, differential buses (e.g., RS-485), or floating grounds - no cathode/anode alignment is required. Layout best practices still mandate symmetric trace routing and direct connection to low-inductance ground planes to preserve clamping speed and effectiveness.
What is the thermal resistance of the 1.5SMC100CAHM3_A/I, and how does it impact power handling?
The 1.5SMC100CAHM3_A/I has a typical junction-to-leads thermal resistance (RθJL) of 15 °C/W and junction-to-ambient (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads. This low RθJL enables efficient heat transfer to PCB copper, sustaining repetitive 1500 W pulses at 0.01% duty cycle. Derating above 25 °C ambient is defined in Figure 2 of the datasheet, and the 1.5SMC100CAHM3_A/I remains within safe operating limits up to TJ = 150 °C.
