Product details
Overview
1V5KE13A from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, featuring 12.4V minimum breakdown voltage (VBR), 11.1V reverse stand-off voltage (VRWM), and 18.2V clamping voltage (VC) at 82A peak pulse current. It protects power rails and I/O lines against ESD, lightning-induced surges, and inductive switching transients in industrial control and automotive electronics.
For engineers reviewing the 1V5KE13A datasheet, 1V5KE13A pinout, 1V5KE13A application, or 1V5KE13A equivalent, key selection criteria include its 11.1V working voltage, 18.2V clamping performance under 82A 10/1000μs surge, DO-201 mechanical compatibility, and <1μA leakage at rated VRWM.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: it remains high-impedance below VRWM = 11.1V, avalanches sharply at VBR ≥ 12.4V, and limits transient energy with low incremental resistance to clamp at VC = 18.2V. Its glass-passivated junction ensures stable breakdown and low leakage.
The device handles 1500W peak pulse power per 1ms waveform, supports 200A non-repetitive forward surge current (8.3ms half-sine), and maintains operation across –55°C to +175°C junction temperature range. Polarity is marked by cathode band on DO-201 body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 11.1 V - Maximum continuous reverse operating voltage before significant leakage begins |
| VBR @ IT=1mA | 12.4–13.7 V - Breakdown voltage range defining reliable avalanche onset threshold |
| VC @ IPPM=82A | 18.2 V - Clamped voltage during 10/1000μs surge, limiting stress on downstream ICs |
| PPPM | 1500 W - Peak pulse power handling capability for transient suppression |
| IR @ VRWM | <1 μA - Ultra-low leakage ensuring minimal standby power loss and signal integrity |
| Junction Temp Range | –55°C to +175°C - Enables use in under-hood automotive and industrial environments |
Pinout & Package
Package: DO-201 axial-leaded plastic case with cathode band marking; RoHS-compliant, halogen-free molding compound (UL 94V-0), pure tin-plated leads solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to ground or lower-potential rail in unidirectional clamping configuration |
| Cathode | Current exit terminal; marked by band | Connected to protected line (e.g., 12V supply or data line) - clamps to anode when overvoltage occurs |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable, repeatable breakdown voltage and long-term reliability under repeated surge stress |
| 1500W peak pulse power (1ms) | Provides robust protection against IEC 61000-4-5 Level 4 (4kV) surges without degradation |
| Low clamping ratio (VC/VBR ≈ 1.43) | Minimizes voltage overshoot during transients, reducing risk of latch-up or damage to 12V-rated ICs |
| <1μA reverse leakage @ VRWM | Preserves signal integrity and battery life in always-on systems such as automotive ECUs |
Applications
| Automotive Power Rail Protection | Industrial PLC Digital I/O Protection |
|---|---|
Use Scenario: 12V battery-supplied microcontroller power input exposed to load-dump and jump-start transients. IC Role / Device Role: Unidirectional shunt TVS placed between VIN and GND to clamp positive surges. Use Value: Limits voltage to ≤18.2V during 82A surge, preventing damage to 16V-rated LDOs and MCU power domains. |
Use Scenario: 24V digital input channel in programmable logic controller subject to field-wiring ESD and inductive kickback. IC Role / Device Role: TVS mounted at connector interface to divert fast transients before signal conditioning circuitry. Use Value: Sub-1μA leakage avoids false triggering; 1500W rating withstands repetitive 10/1000μs surges per IEC 61000-4-4. |
| LED Driver Output Protection | DC-DC Converter Feedback Path Protection |
Use Scenario: Constant-current LED driver output driving long cables susceptible to induced lightning surges. IC Role / Device Role: Unidirectional TVS connected cathode-to-load, anode-to-GND to clamp positive transients only. Use Value: 11.1V VRWM allows full dimming range down to ~10V while blocking normal operation leakage. |
Use Scenario: Voltage feedback node of isolated flyback converter where precision resistive divider connects to secondary-side controller. IC Role / Device Role: Low-capacitance TVS (typ. <50pF) placed across feedback resistor to suppress coupling noise without affecting loop stability. Use Value: 18.2V clamping prevents controller latch-up during 1kV EFT bursts, preserving regulation accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ12A | Lower PPPM (600W), higher VRWM (12V), same DO-214AA package | Better suited for space-constrained PCBs but insufficient for 1500W IEC 61000-4-5 Level 4 compliance | Select 1V5KE13A when full 1500W surge margin is required; SMBJ12A fits tighter layouts with reduced power headroom |
| 1N6274A | Same manufacturer, identical electrical specs and DO-201 package; obsolete JEDEC prefix | No functional difference - direct legacy replacement with identical footprint and performance | 1V5KE13A is the current TSC ordering code; 1N6274A may be available in legacy inventory but shares all design parameters |
Compared with SMBJ12A and 1N6274A, the 1V5KE13A delivers certified 1500W surge capacity in the proven DO-201 form factor, while maintaining sub-1μA leakage and 18.2V clamping - critical for protecting 12V-system MCUs and analog front-ends where voltage margin is tight.

FAQ
What is the maximum clamping voltage of the 1V5KE13A under standard test conditions?
The 1V5KE13A exhibits a maximum clamping voltage (VC) of 18.2 V when subjected to an 82 A peak pulse current with a 10/1000 μs waveform. This value is measured at TA = 25°C and defines the upper voltage limit imposed on protected circuits during surge events. The 1V5KE13A maintains this clamping performance consistently due to its glass-passivated junction and low incremental resistance.
Is the 1V5KE13A suitable for bidirectional transient protection?
No, the 1V5KE13A is a unidirectional TVS diode intended for DC or single-polarity signal line protection. For bidirectional applications, the equivalent part is 1V5KE13CA, which adds a "C" suffix and provides symmetrical clamping in both directions. The 1V5KE13A has a cathode band marking and must be oriented with cathode toward the protected line to function correctly.
What package type does the 1V5KE13A use, and what are its key mechanical attributes?
The 1V5KE13A uses the DO-201 axial-leaded package with a molded plastic body meeting UL 94V-0 flammability rating. It features pure tin-plated leads compliant with J-STD-002 solderability requirements, polarity indicated by a cathode band, and a typical weight of 0.090 g. Its dimensions conform to standard JEDEC DO-201 outlines for through-hole mounting and manual rework.
How does the 1V5KE13A compare to the older 1N6274A part number?
The 1V5KE13A is the current-generation replacement for 1N6274A, sharing identical electrical specifications (VRWM = 11.1 V, VBR = 12.4–13.7 V, VC = 18.2 V), DO-201 package, and performance characteristics. TSC updated the part numbering to the 1V5KEx format for consistency across the series; no design changes or parameter deviations exist between 1V5KE13A and 1N6274A.
What is the reverse leakage current specification for the 1V5KE13A at its rated stand-off voltage?
The 1V5KE13A specifies a maximum reverse leakage current (IR) of less than 1 μA when biased at its rated reverse stand-off voltage (VRWM) of 11.1 V. This ultra-low leakage is confirmed at TA = 25°C and ensures minimal power loss and signal interference in always-on or battery-powered systems where the 1V5KE13A is deployed.
