Product details
Overview
1.5SMC10CAHM3/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage (VC) at 103 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the 1.5SMC10CAHM3/H datasheet, 1.5SMC10CAHM3/H pinout, 1.5SMC10CAHM3/H application, or 1.5SMC10CAHM3/H equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, SMC (DO-214AB) package thermal performance, and compliance with UL 497B surge protector requirements.
Technical Context
This device operates as a voltage-clamped shunt protector: during transients exceeding VWM = 10 V, it avalanches symmetrically in both directions to clamp voltage at ≤14.5 V while diverting up to 103 A (10/1000 µs). Its glass-passivated junction ensures stable breakdown and low leakage (<10 µA at VWM).
Thermally, it delivers RθJA = 75 °C/W (typ.) on standard 8.0 mm × 8.0 mm copper pads and supports continuous operation from −65 °C to +150 °C. The HM3 suffix confirms halogen-free, RoHS-compliant construction and AEC-Q101 qualification for automotive-grade reliability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | Lower PPPM = 600 W; same VWM = 10 V and VC = 17.0 V; SMB package (smaller footprint, higher RθJA). | Not AEC-Q101 qualified; suited for cost-sensitive consumer electronics, not automotive. | Select when space-constrained layout permits lower surge margin and automotive qualification is unnecessary. |
| 1.5KE10CA | Through-hole DO-201 package; identical electrical specs but incompatible with SMT assembly and higher thermal resistance. | Limited to prototyping or legacy through-hole systems; lacks MSL Level 1 and AEC-Q101 support. | Choose only for manual assembly or repair scenarios where SMT compatibility and automotive compliance are not required. |
Compared with SMBJ10CA and 1.5KE10CA, the 1.5SMC10CAHM3/H uniquely combines AEC-Q101 qualification, 1500 W surge rating, and SMC package manufacturability - making it the sole option for production automotive and high-reliability industrial SMT designs requiring certified bidirectional clamping.

FAQ
What is the clamping voltage of the 1.5SMC10CAHM3/H under maximum rated surge current?
The 1.5SMC10CAHM3/H has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current (IPPM) of 103 A with a 10/1000 µs waveform. This value is measured per Fig. 1 and Table 1 in Vishay Document 88303 and ensures protected circuits remain below critical voltage thresholds during surge events. The 1.5SMC10CAHM3/H maintains this clamping performance across its full operating temperature range.
Is the 1.5SMC10CAHM3/H suitable for automotive applications?
Yes, the 1.5SMC10CAHM3/H is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's 1.5SMC Series datasheet (Rev. 09-Mar-2026). It meets stress tests including high-temperature operating life, temperature cycling, and ESD, making it appropriate for under-hood and chassis-mounted automotive electronics. The 1.5SMC10CAHM3/H is explicitly listed for use in sensor units and ECUs per Vishay's typical applications.
What does the "CA" suffix indicate in 1.5SMC10CAHM3/H?
The "CA" suffix in 1.5SMC10CAHM3/H denotes a bidirectional configuration - meaning the device provides symmetrical transient voltage suppression in both forward and reverse directions. Unlike unidirectional variants (e.g., 1.5SMC10AHM3/H), the 1.5SMC10CAHM3/H has no cathode marking and is used where polarity-independent clamping is required, such as across AC lines or differential signal pairs.
What is the thermal resistance of the 1.5SMC10CAHM3/H?
The 1.5SMC10CAHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per Vishay's test conditions (Document 88303, page 3). Its junction-to-lead resistance (RθJL) is 15 °C/W. These values enable reliable thermal management in high-power surge events without external heatsinking in most PCB layouts.
Does the 1.5SMC10CAHM3/H meet UL safety standards?
Yes, the 1.5SMC10CAHM3/H is Underwriters Laboratories (UL) recognized under file E136766 for both unidirectional and bidirectional configurations, compliant with UL 497B for signal circuit protectors. This certification applies to the entire 1.5SMC Series and is documented in Vishay's primary datasheet (Document 88303), confirming suitability for safety-critical telecom and industrial applications.
