Product details
Overview
1V5KE13CA from Taiwan Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-201 package, designed for high-energy surge clamping in power and signal lines. It features 1500W peak pulse power (1ms), 12.4–13.7V breakdown voltage (VBR), 11.1V reverse stand-off voltage (VRWM), 18.2V clamping voltage (VC) at 82A peak pulse current, and operates across –55°C to +175°C junction temperature - used in industrial power supply input protection.
For engineers reviewing the 1V5KE13CA datasheet, 1V5KE13CA pinout, 1V5KE13CA application, or 1V5KE13CA equivalent, key selection criteria include bidirectional clamping capability, low incremental surge resistance, sub-1μA leakage above 11.1V, RoHS/halogen-free compliance, and DO-201 mechanical compatibility with legacy 1N6274A designs.
Technical Context
The 1V5KE13CA implements a glass-passivated silicon junction optimized for fast response (<1 ns) to ESD and electrical fast transients (EFT). Its symmetrical bi-directional structure enables identical clamping behavior in both polarities without external polarity management.
It delivers stable 18.2V clamping at 82A (10/1000μs waveform) with low dynamic impedance, enabling robust protection of downstream DC-DC converters, microcontroller I/O, and relay drivers against inductive switching spikes and lightning-induced surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V - ensures reliable conduction onset within tight tolerance for predictable overvoltage triggering |
| VRWM | 11.1 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 18.2 V at 82 A - clamped voltage seen by protected circuit during full-rated 1500W transient |
| PPPM | 1500 W - peak surge power handling per 1ms pulse, critical for IEC 61000-4-5 Level 4 compliance |
| IR @ VRWM | <1 μA - negligible standby leakage, preserving battery life and signal integrity in always-on systems |
| TJ max | +175 °C - supports operation in high-temperature environments like motor drives and automotive under-hood modules |
Pinout & Package
Package: DO-201 axial leaded package with cathode band marking; meets UL 94V-0 flammability rating and JESD201 Class 2 whisker resistance; 0.090g weight; pure tin-plated leads solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry point in forward bias; common terminal in bi-directional configuration | Electrically symmetric - no functional distinction between anode/cathode in bi-directional mode; cathode band indicates polarity reference only |
| Cathode (banded end) | Current exit point in forward bias; reference marker for orientation | Used for visual alignment during manual assembly; does not affect clamping symmetry but ensures consistent board-level placement |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable long-term reliability and reduced parameter drift under thermal cycling and humidity stress |
| 1500W peak pulse power (1ms) | Supports IEC 61000-4-5 4kV/2Ω surge testing without degradation across 1000+ events |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for 3.3V/5V logic rails |
| Fast response time (<1 ns) | Clamps ESD events (IEC 61000-4-2 ±8kV contact) before sensitive ICs experience latch-up or gate oxide damage |
| RoHS & halogen-free | Complies with IPC-J-STD-609 and IEC 61249-2-21 for environmentally constrained industrial and consumer deployments |
Applications
| Industrial Power Input Protection | Automotive Body Control Module (BCM) I/O |
|---|---|
Use Scenario: 24V DC power feed to PLC I/O modules exposed to load dump and inductive kickback. IC Role / Device Role / Timing Role: Primary surge clamp on main VIN rail upstream of DC-DC converter and LDO regulators. Use Value: Limits transient voltage to ≤18.2V, preventing overvoltage shutdown or destruction of 24V-rated input stage components. | Use Scenario: CAN/LIN bus line protection and sensor interface inputs in BCMs subject to ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bi-directional TVS placed directly at connector entry point before signal conditioning circuitry. Use Value: Clamps both positive and negative transients (e.g., pulse 1/2a/5a) without polarity-sensitive layout constraints. |
| LED Driver Surge Suppression | Smart Meter AC/DC Front-End |
Use Scenario: Output stage of constant-current LED drivers driving high-power arrays in street lighting. IC Role / Device Role / Timing Role: Parallel-connected TVS across output terminals to absorb inductive energy from driver MOSFET turn-off. Use Value: Absorbs up to 1500W surge energy while maintaining <18.2V clamp, protecting LED strings and current-sense resistors. | Use Scenario: Mains-connected smart meter with integrated AC/DC converter and isolated communication interfaces. IC Role / Device Role / Timing Role: Secondary-side transient suppression on DC bus after bridge rectifier and bulk capacitor. Use Value: Prevents false resets and flash memory corruption caused by conducted surges coupled through transformer parasitics. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ13CA | Same DO-214AC (SMA) package; 13V VRWM, 14.4V VBR min, 21.5V VC @ 70A - higher clamping voltage, lower PPPM (400W) | Lower surge rating limits use to sub-IEC 61000-4-5 Level 2; unsuitable for 24V industrial mains interfaces | Select when space-constrained PCBs require surface-mount and surge requirements are ≤400W |
| ON Semiconductor 1.5KE13CA | Identical DO-201 package, same VRWM/VBR/VC specs, 1500W rating - minor parametric variance in IR (≤5μA vs. ≤1μA) | Functionally interchangeable in all 1V5KE13CA applications; validated in telecom power supplies and factory automation | Preferred for dual-sourcing where tighter leakage spec is non-critical and second-source qualification is required |
Compared with SMAJ13CA and 1.5KE13CA, the 1V5KE13CA offers superior leakage performance (<1μA) and identical surge robustness in the same axial package - making it optimal for battery-backed or low-power always-on systems where standby current matters.

FAQ
What is the breakdown voltage range of the 1V5KE13CA?
The 1V5KE13CA has a specified breakdown voltage (VBR) range of 12.4 V to 13.7 V at 1 mA test current, per Taiwan Semiconductor's official datasheet revision D2112. This tight tolerance ensures consistent turn-on behavior across production lots and supports precise overvoltage threshold design in 12V system rails.
Is the 1V5KE13CA unidirectional or bidirectional?
The 1V5KE13CA is a bidirectional TVS diode, indicated by the "CA" suffix. Its electrical characteristics apply identically in both directions, enabling symmetrical clamping of positive and negative transients without polarity-dependent layout - confirmed in the "Devices for Bipolar Applications" section of the datasheet.
What package type does the 1V5KE13CA use?
The 1V5KE13CA uses the DO-201 axial leaded package, as explicitly stated in the Mechanical Data and Ordering Information sections.
