Product details
Overview
1.5SMC13CAHM3/I 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 13 V breakdown voltage (VBR min/max = 12.4 V / 13.7 V), 11.1 V stand-off voltage (VWM), 18.2 V clamping voltage (VC) at 82.4 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC13CAHM3/I datasheet, 1.5SMC13CAHM3/I pinout, 1.5SMC13CAHM3/I application, or 1.5SMC13CAHM3/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMC (DO-214AB) package compatibility, and compliance with UL 497B surge protector requirements for automotive-grade transient suppression.
Technical Context
This device operates as a voltage-clamped shunt protector: during transients exceeding VWM = 11.1 V, it avalanches symmetrically in both directions to clamp line voltage to ≤18.2 V at 82.4 A. Its glass-passivated junction ensures stable breakdown and low leakage (<5 µA at VWM).
Rated for 150 °C maximum junction temperature and MSL Level 1 moisture sensitivity, the 1.5SMC13CAHM3/I supports reflow soldering up to 260 °C peak. Its halogen-free, RoHS-compliant construction (HM3 suffix) and AEC-Q101 qualification confirm suitability for under-hood automotive electronics and industrial control systems requiring long-term reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN bus 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: Shunt TVS diode placed directly at connector entry point to divert surge energy before reaching sensitive ICs. Use Value: Clamps transients to ≤18.2 V within nanoseconds, preventing latch-up or gate oxide damage in 3.3 V/5 V interface ICs. |
Use Scenario: Safeguarding 24 V DC digital input modules in programmable logic controllers against field-wiring induced surges and ESD events. IC Role / Device Role / Timing Role: Primary overvoltage clamp on channel-level signal conditioning circuits upstream of optocouplers or level shifters. Use Value: Maintains <5 µA leakage at 24 V nominal, avoiding false triggering while delivering 1500 W surge immunity per channel. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Secondary protection on Ethernet PHY power rails and RS-485 data lines exposed to lightning-induced surges in outdoor telecom equipment. IC Role / Device Role / Timing Role: Bidirectional clamping element bridging VCC–GND or differential pair lines to suppress common-mode transients. Use Value: Symmetrical 12.4–13.7 V breakdown enables identical protection for both polarities of AC-coupled signals. |
Use Scenario: Input-stage surge suppression on universal-input (90–264 VAC) AC-DC adapters used in smart home hubs and IoT gateways. IC Role / Device Role / Timing Role: Secondary TVS after MOV-based primary protection, absorbing residual fast-rising transients missed by slower bulk devices. Use Value: Fast response time and low incremental resistance ensure clamping occurs before downstream rectifier or controller ICs experience overstress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | Lower peak pulse power (600 W), same VBR/VC, SMB (DO-214AA) package - 30% smaller footprint | Not rated for AEC-Q101; limited to commercial-grade consumer/industrial use | Select when board space is constrained and automotive qualification is unnecessary |
| 1.5KE13CA | Higher leakage (≤1000 µA), axial-leaded DO-15 package, 1500 W rating - legacy through-hole variant | Requires wave soldering; unsuitable for automated SMT assembly or high-density layouts | Select only for legacy repair, prototyping, or non-SMT production environments |
Compared with SMBJ13CA and 1.5KE13CA, the 1.5SMC13CAHM3/I delivers AEC-Q101 validation, halogen-free compliance, and optimized thermal performance in the SMC package - making it the preferred choice for new automotive and high-reliability industrial designs requiring SMT scalability and long-term supply assurance.

FAQ
What is the clamping voltage of the 1.5SMC13CAHM3/I under a 10/1000 µs surge?
The 1.5SMC13CAHM3/I clamps to a maximum of 18.2 V when subjected to its rated peak pulse current of 82.4 A with a 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88303 and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Is the 1.5SMC13CAHM3/I suitable for automotive applications?
Yes - the 1.5SMC13CAHM3/I carries the HM3 suffix, confirming it is halogen-free, RoHS-compliant, and AEC-Q101 qualified. It has undergone rigorous stress testing for temperature cycling, humidity, and mechanical shock, making it approved for use in engine control units, ADAS sensors, and body electronics per automotive OEM requirements.
Does the 1.5SMC13CAHM3/I have polarity markings on the package?
No - the 1.5SMC13CAHM3/I is a bidirectional TVS diode and carries no polarity marking. Its symmetrical construction means either terminal functions as anode or cathode depending on transient polarity, enabling flexible PCB layout without orientation constraints.
What is the maximum operating junction temperature for the 1.5SMC13CAHM3/I?
The 1.5SMC13CAHM3/I has a maximum junction temperature (TJ) of +150 °C, as specified in the Absolute Maximum Ratings table of Vishay document 88303. This rating supports reliable operation in under-hood automotive environments and thermally demanding industrial enclosures.
How does the 1.5SMC13CAHM3/I differ from unidirectional variants like 1.5SMC13AHM3/I?
The 1.5SMC13CAHM3/I is bidirectional (denoted by "CA"), providing symmetrical clamping for AC signals or differential lines, whereas 1.5SMC13AHM3/I is unidirectional ("A") with a cathode band marking and only clamps in reverse bias. Their VBR, VC, and PPPM ratings are identical, but circuit topology determines correct selection.
