Product details
Overview
1V5KE10A from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 9.5–10.5 V breakdown voltage (VBR), 8.55 V reverse stand-off voltage (VRWM), and 14.5 V clamping voltage (VC) at 10 A 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 subsystems.
For engineers reviewing the 1V5KE10A datasheet, 1V5KE10A pinout, 1V5KE10A application, or 1V5KE10A equivalent, key selection criteria include its 1500W 1ms pulse rating, low 14.5 V clamping at 10 A, <1 µA leakage above 10 V, DO-201 mechanical compatibility, and bipolar-capable variants (1V5KE10CA) for AC-coupled protection.
Technical Context
The 1V5KE10A operates as a silicon avalanche diode with glass-passivated junction, optimized for fast response (<1 ns) to transient overvoltages. Its unidirectional configuration provides low forward voltage drop during normal operation while delivering precise clamping at 14.5 V under 10 A 10/1000 µs surge conditions.
It meets JEDEC JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements. The device sustains 200 A non-repetitive forward surge current (8.3 ms half-sine) and operates across –55 °C to +175 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.5 V / 10.5 V - defines guaranteed avalanche conduction onset range at 1 mA test current |
| VRWM | 8.55 V - maximum continuous reverse voltage before significant leakage begins |
| VC @ IPPM=10 A | 14.5 V - clamped voltage during 10/1000 µs surge, limiting downstream IC stress |
| PPPM | 1500 W - peak pulse power handling capability per 1 ms waveform, critical for lightning immunity |
| IR @ VRWM | <1 µA - ultra-low leakage ensures minimal standby power loss in battery-powered systems |
| TJ max | +175 °C - enables use in high-temperature engine bay or industrial motor drive environments |
| Package | DO-201 - industry-standard axial leaded package with 0.090 g mass and tin-plated leads per J-STD-002 |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy-molded body with cathode band marking. Cathode terminal is marked by a band; anode is unmarked end. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference node | Connected to lower-potential side (e.g., GND or return path); establishes polarity for unidirectional clamping |
| Cathode | Avalanche conduction output / Clamping node | Connected to protected line (e.g., 12 V rail); conducts surge current to anode when VAK exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity stress |
| 1500 W peak pulse power (1 ms) | Supports IEC 61000-4-5 Level 4 (4 kV line-to-line) surge immunity without derating |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for 3.3 V/5 V logic |
| Fast response time (<1 ns) | Clamps before sensitive downstream circuitry experiences damaging overvoltage |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and global environmental regulations for industrial and automotive PCB assembly |
Applications
| Automotive Power Rail Protection | Industrial PLC Digital I/O Protection |
|---|---|
Use Scenario: Protecting 12 V supply lines in vehicle body control modules from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and DC-DC input, clamping transients before they reach regulator ICs. Use Value: Withstands 1500 W surges and clamps to 14.5 V, preventing regulator latch-up or MOSFET gate oxide failure. | Use Scenario: Shielding 24 V digital input channels in programmable logic controllers from field-wiring EFT and inductive kickback. IC Role / Device Role / Timing Role: TVS connected between input terminal and common, shunting transients away from optocoupler or Schmitt trigger inputs. Use Value: Sub-1 µA leakage avoids false triggering; 14.5 V clamping preserves signal integrity for 24 V logic thresholds. |
| LED Driver Surge Suppression | AC-DC Adapter Input Stage |
Use Scenario: Safeguarding constant-current LED driver ICs in streetlight systems exposed to lightning-induced surges on long feeder cables. IC Role / Device Role / Timing Role: Mounted across primary-side bulk capacitor input to clamp differential-mode surges before rectifier and controller. Use Value: 1500 W rating handles multi-kA induced currents; DO-201 footprint allows direct replacement of legacy 1.5KE series. | Use Scenario: Protecting bridge rectifier inputs in universal-input AC-DC adapters against line surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Unidirectional TVS placed across AC input terminals (L–N), conducting only during positive half-cycle overvoltage events. Use Value: 8.55 V VRWM permits safe operation on 120/230 VAC RMS with full-wave rectification; 14.5 V VC limits stress on NTC and X-capacitor. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse P6KE10A | Same DO-201 package, identical VRWM (8.55 V), but VC = 15.0 V @ 10 A (0.5 V higher) | Slightly higher clamping increases stress margin on downstream 12 V regulators | Acceptable where 0.5 V clamping difference is within system safety margin |
| ON Semiconductor 1.5KE10A | Identical electrical specs and DO-201 package; same VBR, VRWM, VC, and PPPM; RoHS-compliant variant available | No functional deviation; validated in same automotive and industrial reference designs | Drop-in alternative with identical performance and qualification history |
Compared with 1V5KE10A, P6KE10A offers marginally higher clamping voltage but broader global distribution, while 1.5KE10A delivers exact electrical equivalence and proven interoperability in legacy designs-making it the preferred choice for design continuity and qualification reuse.

FAQ
What is the breakdown voltage tolerance of the 1V5KE10A?
The 1V5KE10A has a specified breakdown voltage (VBR) range of 9.5 V to 10.5 V at 1 mA test current, representing ±5% tolerance around the nominal 10 V rating. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable system-level surge margin calculations in designs using the 1V5KE10A.
Is the 1V5KE10A suitable for bidirectional transient protection?
No-the 1V5KE10A is unidirectional. For bidirectional protection, the pin-compatible 1V5KE10CA variant must be used. The "C" suffix denotes symmetrical breakdown in both polarities, enabling AC line or data-line protection where reversals occur. Using 1V5KE10A in bidirectional applications risks open-circuit failure during negative transients.
What is the maximum allowable junction temperature for continuous operation of the 1V5KE10A?
The 1V5KE10A supports continuous operation up to +175 °C junction temperature, verified per absolute maximum ratings. At ambient temperatures above 75 °C, derating applies: power dissipation drops linearly to zero at +175 °C. This high TJ rating makes the 1V5KE10A suitable for under-hood automotive and enclosed industrial power supplies where thermal management is constrained.
How does the clamping voltage of the 1V5KE10A compare to its breakdown voltage?
The 1V5KE10A clamps to 14.5 V at 10 A peak pulse current (10/1000 µs), which is ~45 % above its minimum breakdown voltage (9.5 V). This VC/VBR ratio reflects low dynamic impedance and efficient energy diversion. Designers use this 14.5 V value-not VBR-to verify downstream component voltage ratings when applying the 1V5KE10A in actual circuits.
Can the 1V5KE10A replace older 1.5KE10A parts in existing designs?
Yes-the 1V5KE10A is a direct form-fit-function replacement for ON Semiconductor's 1.5KE10A, sharing identical DO-201 package dimensions, electrical specifications (VRWM, VBR, VC, PPPM), and thermal ratings. No PCB layout changes or schematic updates are required when substituting 1V5KE10A for 1.5KE10A in qualified designs.
