Product details
Overview
1.5SMC100CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 100 V standoff voltage (VWM), 114–126 V breakdown voltage (VBR), 1500 W peak pulse power (10/1000 µs), clamping voltage of 137 V at 10.9 A, and operates across -65 °C to +150 °C. It is used in automotive sensor interfaces and industrial I/O protection where fast response and high surge immunity are required.
For engineers reviewing the 1.5SMC100CAHM3/H datasheet, 1.5SMC100CAHM3/H pinout, 1.5SMC100CAHM3/H application, or 1.5SMC100CAHM3/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, SMC (DO-214AB) package details, clamping performance data, and real-world use context for ESD and lightning transient suppression in bidirectional signal paths.
Technical Context
This device functions as a voltage-clamping protector with symmetrical bidirectional conduction-no polarity marking required-and responds within picoseconds to transients exceeding its VWM threshold. Its glass-passivated junction ensures stable leakage (<1 µA at 85.5 V) and low incremental surge resistance, enabling consistent clamping under repetitive 10/1000 µs surges at 0.01% duty cycle.
The 1.5SMC100CAHM3/H is rated for 1500 W peak pulse power and supports 10.9 A peak pulse current (IPPM) while maintaining a maximum clamping voltage of 137 V. Its thermal resistance (RθJA = 75 °C/W) and MSL Level 1 rating support reflow compatibility up to 260 °C, and its halogen-free, RoHS-compliant construction meets automotive-grade reliability requirements per AEC-Q101.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protecting LIN/CAN transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across differential bus lines or supply rails upstream of transceiver ICs. Use Value: Clamps transients to ≤137 V while sustaining 1500 W surges, preventing latch-up or permanent damage to AEC-Q100 qualified transceivers. |
Use Scenario: Safeguarding two-wire CAN FD physical layer circuits against ESD (IEC 61000-4-2) and coupled surges in factory automation controllers. IC Role / Device Role / Timing Role: Symmetrical TVS mounted across CAN_H/CAN_L lines to suppress common-mode and differential-mode transients. Use Value: Sub-nanosecond response and low clamping voltage preserve signal edge integrity and prevent bit errors during high-speed CAN FD communication. |
| Telecom Line Interface | Power Supply Input Protection |
Use Scenario: Shielding Ethernet PHYs and PoE injectors from lightning-induced surges on outdoor-facing RJ45 ports in network switches and base stations. IC Role / Device Role / Timing Role: Bidirectional TVS deployed on each twisted pair (e.g., pairs 1–2, 3–6) before magnetics and PHY ICs. Use Value: 137 V clamping ensures safe operation below Ethernet IC absolute maximum ratings (typically 150 V), even under repeated 10/1000 µs strikes. |
Use Scenario: Guarding 24 V DC input rails of PLC I/O modules against inductive switching spikes from solenoids and relays. IC Role / Device Role / Timing Role: TVS placed between rail and ground to shunt energy away from DC-DC converters and microcontrollers. Use Value: 1500 W rating handles worst-case 100 mJ surges from 24 V/1 A inductive loads, reducing need for additional RC snubbers or varistors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Lower PPPM (600 W), same VWM (85.5 V), SMB package (smaller footprint, higher RθJA) | Preferred for space-constrained consumer electronics; insufficient for automotive load-dump events | Select when board area is critical and surge energy is ≤600 W |
| 1.5KE100CA | Through-hole DO-201 package, identical electrical specs but incompatible with SMT assembly | Used in legacy industrial power supplies where manual assembly or high-reliability through-hole mounting is mandated | Choose only if SMT is not available and mechanical robustness outweighs automated placement needs |
Compared with SMBJ100CA and 1.5KE100CA, the 1.5SMC100CAHM3/H uniquely combines AEC-Q101 qualification, 1500 W surge capacity, and SMC surface-mount compatibility-making it the only option among the three qualified for new automotive designs requiring both high-power transient suppression and automated manufacturing.

FAQ
What does the "HM3" suffix indicate in 1.5SMC100CAHM3/H?
The "HM3" suffix in 1.5SMC100CAHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It confirms the device meets automotive-grade reliability standards-including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling-and is suitable for under-hood and safety-critical electronic control units.
Is 1.5SMC100CAHM3/H unidirectional or bidirectional?
The 1.5SMC100CAHM3/H is a bidirectional TVS diode, indicated by the "CA" suffix. It provides symmetrical clamping in both polarities with no cathode band marking, making it ideal for protecting AC-coupled lines, differential buses like CAN or RS-485, and any circuit where voltage transients may swing positive or negative relative to ground.
What is the maximum clamping voltage of 1.5SMC100CAHM3/H at rated surge current?
The maximum clamping voltage (VC) of 1.5SMC100CAHM3/H is 137 V, measured at its peak pulse current (IPPM) of 10.9 A under the standard 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Can 1.5SMC100CAHM3/H replace older 1.5SMC100CA-E3 parts in existing designs?
Yes, 1.5SMC100CAHM3/H is a direct functional and mechanical replacement for 1.5SMC100CA-E3, sharing identical SMC (DO-214AB) package dimensions, electrical specifications (VWM, VBR, VC), and thermal characteristics. The HM3 version adds halogen-free material content and AEC-Q101 qualification-enhancing suitability for automotive and green-compliance programs without layout changes.
What is the junction-to-ambient thermal resistance (RθJA) of 1.5SMC100CAHM3/H?
The typical junction-to-ambient thermal resistance (RθJA) of 1.5SMC100CAHM3/H is 75 °C/W when mounted on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad per terminal. This value supports reliable thermal dissipation during repetitive surge events and informs PCB layout decisions for sustained power handling.
