Product details
Overview
1.5SMC13 from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 11.7–14.3 V breakdown voltage (VBR), 10.5 V working stand-off voltage (VWM), 19.0 V maximum clamping voltage (VC) at 82 A peak pulse current, and 1500 W peak pulse power rating per 10/1000 µs waveform - deployed in telecom front-ends, industrial I/O modules, and automotive body-control ECUs.
For engineers reviewing the 1.5SMC13 datasheet, 1.5SMC13 pinout, 1.5SMC13 application, or 1.5SMC13 equivalent, key selection criteria include its DO-214AB (SMC) package compatibility, unidirectional polarity marking, sub-1 ps response time, <1 µA leakage at VWM, and ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance for automotive transients.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<1 µA IR at 10.5 V), then rapidly avalanches below 19.0 V to divert surge energy away from downstream ICs. Its glass-passivated junction ensures stable VBR tolerance (±5% for 1.5SMC13A variant; ±10% for 1.5SMC13) and robust ESD immunity up to ±30 kV (HBM).
Thermally, it sustains 150°C junction temperature with RθJC = 15°C/W and RθJA = 50°C/W, enabling reliable operation in enclosed industrial enclosures without forced airflow. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity - suitable for standard reflow profiles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1.0 mA | 11.7–14.3 V - defines minimum voltage at which avalanche conduction begins; sets lower bound of clamping window |
| VWM | 10.5 V - maximum continuous reverse operating voltage; must exceed system nominal rail (e.g., 9–10 V logic supply) |
| VC @ IPPM = 82 A | 19.0 V - clamped voltage during 10/1000 µs surge; determines protected circuit's maximum stress level |
| PPK | 1500 W - peak pulse power handling per single transient; supports 82 A surges without failure |
| IR @ VWM | <1 µA - ultra-low leakage ensures minimal standby power loss and no signal distortion in high-impedance paths |
| Response Time | <1.0 ps - enables suppression before ESD or lightning-induced transients reach sensitive inputs |
| TJ Max | +150°C - allows operation in under-hood automotive or sealed industrial environments without derating |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, molded plastic case with matte tin-plated leads; cathode indicated by band marking; polarity-critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-voltage return path; completes shunt path during avalanche |
| Cathode | Protected line input | Connected to line being protected (e.g., 12 V supply rail); marked with band on package |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR over temperature and lifetime; eliminates parameter drift in harsh thermal cycles |
| ISO 7637-2 compliance | Validated for automotive load-dump and inductive-switching transients (Pulse 1/2a/2b/3a/3b), not just ESD |
| DO-214AB mechanical robustness | UL 94V-0 rated molding compound withstands reflow soldering and mechanical stress in high-vibration environments |
| J-STD-020 Level 1 moisture rating | Enables use without baking or special handling - reduces manufacturing overhead and risk of popcorning |
| Fast response <1 ps | Clamps before transient edge propagates into microcontroller GPIO or CAN transceiver inputs |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |
|---|---|
Use Scenario: Protecting 12 V supply rail against load dump (ISO 7637-2 Pulse 5a) and alternator switching transients. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between VIN and GND upstream of DC-DC converter input. Use Value: Clamps surge to ≤19.0 V, preventing overvoltage damage to 24 V-rated buck controller ICs while maintaining >10.5 V hold-up during normal operation. |
Use Scenario: Safeguarding 24 V digital input channels from field-wiring induced surges and ESD events. IC Role / Device Role / Timing Role: Line-side TVS on each optocoupler input, directly across terminals before series current-limiting resistor. Use Value: Limits transient voltage to 19.0 V within 1 ps, ensuring optocoupler LED remains within safe reverse-bias limit and avoids latch-up in upstream FPGA I/O banks. |
| Telecom Power Feeder Protection | Consumer Appliance Motor Driver Board |
Use Scenario: Secondary-side surge protection on -48 V DC telecom power distribution board feeding baseband processors. IC Role / Device Role / Timing Role: Unidirectional TVS referenced to chassis ground, placed after bulk filter capacitor but before point-of-load regulator. Use Value: Absorbs 1500 W pulses from lightning-induced coupling without degradation, preserving -48 V rail integrity and avoiding brownout resets. |
Use Scenario: Suppressing inductive kickback from brushed DC motor commutation on smart appliance control boards. IC Role / Device Role / Timing Role: TVS mounted across motor terminals, oriented to clamp negative-going flyback spikes relative to ground-referenced H-bridge driver outputs. Use Value: Clamps reverse spikes to ≤19.0 V, preventing gate oxide rupture in N-channel MOSFETs and eliminating false triggering of overvoltage fault detection circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A (Bourns) | Same DO-214AA (SMB) package; tighter VBR tolerance (±5%), lower VC = 21.5 V at 62 A; 600 W rating | Limited to lower-energy surges; unsuitable for ISO 7637-2 Pulse 5a load dump | Select when space-constrained layouts require smaller SMB footprint and surge requirements are limited to IEC 61000-4-2/4-5 |
| 1.5KE13A (ON Semiconductor) | Through-hole DO-15 package; identical VBR/VC specs but higher RθJA = 60°C/W; 1500 W rating | Requires PCB through-hole real estate and wave-solder process; incompatible with fully SMT assembly | Choose only for legacy through-hole designs or where thermal mass of lead-frame improves long-duration surge handling |
Compared with SMBJ13A and 1.5KE13A, the 1.5SMC13 offers superior surge energy handling in a compact SMC package with automotive-grade transient certification - making it optimal for new SMT-based automotive and industrial power rail protection where both space and ruggedness are critical.

FAQ
What is the polarity configuration of the 1.5SMC13?
The 1.5SMC13 is a unidirectional TVS diode with cathode indicated by a band on the DO-214AB (SMC) package. It conducts only during reverse-biased overvoltage events - meaning the banded end connects to the protected line (e.g., +12 V rail), and the anode connects to ground. This configuration ensures zero forward conduction during normal operation and precise clamping on negative transients.
Does the 1.5SMC13 meet automotive transient standards?
Yes, the 1.5SMC13 meets ISO 7637-2 requirements for Pulse 1 (inductive load disconnect), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling), as confirmed in Taiwan Semiconductor's official documentation. It is not rated for Pulse 5a (load dump), which requires higher clamping energy handling - that role is fulfilled by the 1.5SMC13A variant or higher-voltage members of the same family.
What is the maximum clamping voltage of the 1.5SMC13 under surge conditions?
The 1.5SMC13 has a maximum clamping voltage (VC) of 19.0 V when subjected to an 82 A peak pulse current with a 10/1000 µs waveform. This value is measured at the device terminals and represents the highest voltage seen by downstream circuitry during worst-case transient events - critical for ensuring connected ICs remain within absolute maximum ratings.
Can the 1.5SMC13 be used in bidirectional applications?
No - the 1.5SMC13 is strictly unidirectional. For bidirectional protection (e.g., AC signal lines or differential buses), Taiwan Semiconductor specifies variants with "C" or "CA" suffixes (e.g., 1.5SMC13C). Using the 1.5SMC13 in reverse-biased AC configurations risks permanent failure due to forward conduction and thermal runaway during positive half-cycles.
What is the leakage current specification for the 1.5SMC13 at its working voltage?
The 1.5SMC13 exhibits a maximum blocking leakage current (IR) of less than 1 µA when biased at its rated working stand-off voltage (VWM) of 10.5 V. This ultra-low leakage ensures negligible power loss in battery-powered systems and prevents signal integrity issues in high-impedance sensor interfaces or precision analog front-ends.
