Product details
Overview
1.5SMC13CAHE3/9AT 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: 12.4–13.7 V at 1.0 mA), 11.1 V standoff voltage (VWM), clamps to ≤18.2 V at 82.4 A peak pulse current (10/1000 µs), and delivers 1500 W peak pulse power. It is AEC-Q101 qualified and used in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC13CAHE3/9AT datasheet, 1.5SMC13CAHE3/9AT pinout, 1.5SMC13CAHE3/9AT application, or 1.5SMC13CAHE3/9AT equivalent, key selection criteria include bidirectional clamping capability, low clamping voltage under high surge current, AEC-Q101 qualification status, SMC (DO-214AB) package thermal performance, and compatibility with automated SMT assembly.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<5.0 µA at VWM), while the low incremental surge resistance enables rapid energy dissipation during transients.
The device is rated for 1500 W peak pulse power (10/1000 µs waveform) and supports repetitive surges at 0.01% duty cycle. Thermal resistance is 75 °C/W (junction-to-ambient, on recommended 8.0 mm × 8.0 mm copper pads) and 15 °C/W (junction-to-leads), enabling reliable operation up to TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min–max) | 12.4–13.7 V at 1.0 mA - defines precise voltage threshold where avalanche conduction begins reliably |
| VWM | 11.1 V - maximum continuous reverse operating voltage before significant leakage onset |
| VC @ IPPM | ≤18.2 V at 82.4 A - clamping voltage under full 1500 W transient, critical for downstream IC survivability |
| PPPM | 1500 W - peak surge power handling capacity per 10/1000 µs standard waveform |
| IPPM | 82.4 A - maximum non-repetitive surge current the device safely clamps without failure |
| TJ max | +150 °C - maximum junction temperature, supporting under-hood automotive and industrial ambient conditions |
| Qualification | AEC-Q101 qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Molding compound meets UL 94 V-0. No polarity marking - bidirectional symmetry eliminates cathode/anode distinction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals function identically; voltage clamping occurs regardless of polarity - no orientation required during placement |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| 1500 W peak pulse power | Withstands severe lightning-induced surges (IEC 61000-4-5 Level 4) and inductive switch-off spikes |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules, body electronics, and ADAS sensor interfaces |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes stress on protected circuitry - e.g., 18.2 V clamp protects 12 V rail logic with margin |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without moisture sensitivity handling |
Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from load dump and ESD events in vehicle cabins. IC Role / Device Role / Timing Role: Bidirectional TVS placed at connector entry point to shunt transients before they reach sensitive interface ICs. Use Value: Clamps 10/1000 µs surges to ≤18.2 V, preserving signal integrity and preventing latch-up in 3.3 V/5 V microcontrollers and ADCs. |
Use Scenario: Safeguarding 4–20 mA current loop inputs and ±10 V analog inputs in programmable logic controllers against field wiring faults and electrostatic discharge. IC Role / Device Role / Timing Role: Primary overvoltage clamp on input terminals, working in concert with series current-limiting resistors and filtering capacitors. Use Value: Withstands repeated 1 kV/500 A surge events per IEC 61000-4-5, ensuring long-term reliability in factory-floor environments. |
| Telecom Power Supply Rail | Consumer USB Port Protection |
Use Scenario: Secondary protection on +12 V or +48 V DC power rails feeding telecom base station subsystems exposed to induced lightning surges. IC Role / Device Role / Timing Role: Fast-response crowbar element that diverts surge energy away from DC-DC converters and PMICs. Use Value: 1500 W rating and 82.4 A IPPM provide headroom above typical telecom surge requirements (e.g., GR-1089 Level 3). |
Use Scenario: Overvoltage suppression on VBUS and D+/D− lines of USB 2.0 ports in smart home hubs and set-top boxes subjected to user-handling ESD. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing ±15 kV contact ESD (IEC 61000-4-2) before it couples into USB PHY ICs. Use Value: Low VWM (11.1 V) avoids interference with 5 V nominal operation while maintaining <5 µA leakage at room temperature. |
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 power (600 W), same VBR range and SMC-compatible SMB (DO-214AA) package | Not AEC-Q101 qualified; suitable for cost-sensitive consumer or industrial non-automotive use | Select when 600 W surge capacity suffices and automotive qualification is unnecessary |
| 1.5KE13CA | Higher power (1500 W), axial-lead DO-201AD package - not surface-mountable | Requires through-hole assembly; incompatible with automated SMT lines and space-constrained PCBs | Select only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMBJ13CA and 1.5KE13CA, the 1.5SMC13CAHE3/9AT uniquely combines AEC-Q101 qualification, SMC surface-mount compatibility, and full 1500 W surge capability - making it the only choice for production automotive SMT designs requiring certified reliability and high-energy clamping.

FAQ
What is the clamping voltage of the 1.5SMC13CAHE3/9AT under maximum surge current?
The 1.5SMC13CAHE3/9AT clamps to a maximum of 18.2 V when subjected to its rated peak pulse current of 82.4 A (10/1000 µs waveform). This value is measured per standard test conditions and guarantees protection margin for 12 V systems. The 1.5SMC13CAHE3/9AT maintains this clamping performance across its full operating temperature range.
Is the 1.5SMC13CAHE3/9AT unidirectional or bidirectional?
The 1.5SMC13CAHE3/9AT is a bidirectional TVS diode, indicated by the "CA" suffix. It provides symmetrical clamping in both polarities, with identical VBR, VWM, and VC specifications for positive and negative transients. There is no polarity marking on the device - orientation during placement is irrelevant.
Does the 1.5SMC13CAHE3/9AT meet automotive reliability standards?
Yes - the "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification. The 1.5SMC13CAHE3/9AT has passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 Rev D, making it suitable for under-hood and cabin automotive applications.
What package does the 1.5SMC13CAHE3/9AT use, and is it compatible with standard SMT processes?
The 1.5SMC13CAHE3/9AT uses the SMC (DO-214AB) package - a low-profile, surface-mount outline with 3.20 mm minimum terminal width. It meets MSL Level 1 and is compatible with standard lead-free reflow profiles (peak 260 °C), requiring no special moisture handling or process adjustments.
How does the 1.5SMC13CAHE3/9AT compare to the 1.5SMC13A variant?
The 1.5SMC13CAHE3/9AT is the bidirectional, AEC-Q101-qualified version; the 1.5SMC13A is unidirectional and commercial-grade. Key differences include polarity marking (cathode band on 1.5SMC13A), absence of automotive qualification, and asymmetric conduction. The 1.5SMC13CAHE3/9AT must be used where bidirectional protection or automotive compliance is required.
