Product details
Overview
1.5SMC10CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection on signal and power lines. It features 1500 W peak pulse power (10/1000 μs), 14.5 V maximum clamping voltage at 103 A peak pulse current, and 10 V standoff voltage - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC10CAHM3/I datasheet, 1.5SMC10CAHM3/I pinout, 1.5SMC10CAHM3/I application, or 1.5SMC10CAHM3/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, halogen-free RoHS compliance, and compatibility with 8.0 mm × 8.0 mm copper pad layouts per JEDEC standards.
Technical Context
This device operates as a voltage-clamped transient protector using an avalanche junction structure. Its bidirectional symmetry enables identical clamping behavior in both polarities, with breakdown voltage specified at 10.5–11.6 V (min/max) under 1 mA test current and 14.5 V clamping at 103 A IPPM.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15 °C/W, supporting operation up to TJ = +150 °C. The device meets MSL Level 1 per J-STD-020 and is qualified to AEC-Q101 for automotive use - confirmed by HM3 suffix and ordering code "I" denoting 13" tape-and-reel packaging.

Use Value: Provides precise 10 V standoff and low leakage (<10 μA), avoiding unnecessary standby current draw in energy-efficient designs. |
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 peak power (600 W), same 10 V VWM and bidirectional configuration, SMB package (smaller footprint) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 3/4 testing | Select when board space is constrained and surge threat level is moderate (e.g., indoor consumer ports) |
| 1.5KE10CA | Through-hole TO-218 package, same 10 V VWM and 1500 W rating, but higher thermal resistance and no AEC-Q101 qualification | Not suitable for automated SMT assembly or automotive under-hood use due to package and qualification gap | Choose only for legacy through-hole designs where rework flexibility outweighs production efficiency needs |
Compared with SMBJ10CA and 1.5KE10CA, the 1.5SMC10CAHM3/I delivers automotive-grade reliability in a compact SMT package with full 1500 W surge capacity - making it optimal for new designs requiring AEC-Q101 compliance and high-volume automated manufacturing.

FAQ
What is the clamping voltage of the 1.5SMC10CAHM3/I at its rated peak pulse current?
The 1.5SMC10CAHM3/I has a maximum clamping voltage (VC) of 14.5 V at 103 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value ensures downstream circuitry remains protected below critical voltage thresholds during surge events, and is verified per the Vishay 88303 datasheet Table on page 2.
Is the 1.5SMC10CAHM3/I suitable for automotive applications?
Yes, the 1.5SMC10CAHM3/I is AEC-Q101 qualified, as indicated by the "HM3" suffix and confirmed in the Vishay 1.5SMC Series datasheet revision 09-Mar-2026. It supports operating junction temperatures up to +150 °C and meets MSL Level 1, making it appropriate for under-hood and ADAS sensor interface applications.
What does the "CA" suffix mean in 1.5SMC10CAHM3/I?
The "CA" suffix in 1.5SMC10CAHM3/I denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical electrical characteristics (VWM, VBR, VC) regardless of voltage polarity. This is distinct from unidirectional "A" variants which feature a marked cathode band.
What package type does the 1.5SMC10CAHM3/I use, and what are its mounting requirements?
The 1.5SMC10CAHM3/I uses the SMC (DO-214AB) surface-mount package, with recommended mounting on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. Its thermal resistance is RθJA = 75 °C/W, and it complies with J-STD-002 for solderability and JESD 22-B102 for lead finish reliability.
How does the 1.5SMC10CAHM3/I differ from the 1.5SMC10A variant?
The 1.5SMC10CAHM3/I is bidirectional and AEC-Q101 qualified with halogen-free RoHS compliance (HM3), whereas the 1.5SMC10A is unidirectional, commercial-grade (E3/M3), and lacks automotive qualification. Their clamping voltages differ slightly: 14.5 V (CA) vs. 14.5 V (A), but polarity behavior and qualification status are functionally distinct.
