Product details
Overview
1V5KE100A from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, featuring 95–105 V breakdown voltage (VBR), 85.5 V reverse stand-off voltage (VRWM), and 137 V clamping voltage (VC) at 11.0 A peak pulse current. It protects power rails and I/O lines against ESD, lightning-induced surges, and inductive switching transients in industrial power supplies and automotive control modules.
For engineers reviewing the 1V5KE100A datasheet, 1V5KE100A pinout, 1V5KE100A application, or 1V5KE100A equivalent, key selection criteria include verified unidirectional clamping performance at 1ms pulse, low incremental surge resistance (<0.5 Ω typical), sub-1 μA leakage above 10 V, RoHS/halogen-free compliance, and DO-201 mechanical compatibility with standard through-hole PCB layouts.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (>1 GΩ), then avalanches sharply at VBR = 95–105 V to limit transient energy. Its glass-passivated junction ensures stable breakdown and low leakage across -55°C to +175°C junction temperature range.
The device delivers 1500 W peak pulse power (10/1000 µs waveform), with clamping voltage tightly controlled at 137 V (max) at 11.0 A IPPM. Its fast response time (<1.0 ns) and low dynamic impedance enable effective suppression of EFT (IEC 61000-4-4) and surge (IEC 61000-4-5) events without affecting system signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 95 V / 105 V - Ensures reliable avalanche initiation before downstream IC damage threshold (e.g., 120 V rail margin) |
| VRWM | 85.5 V - Maximum continuous reverse operating voltage; sets safe DC bias ceiling for 100 V nominal systems |
| VC @ IPPM | 137 V - Clamped voltage during 11.0 A 10/1000 µs surge; defines worst-case stress on protected circuitry |
| PPPM | 1500 W - Peak pulse power handling at 1 ms; supports IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge immunity |
| IR @ VRWM | <1 µA - Negligible standby leakage; avoids battery drain or sensor offset in always-on circuits |
| TJMAX | +175 °C - Enables operation in high-temperature environments such as engine control units or enclosed power converters |
| Package | DO-201 - Standard axial-leaded through-hole package; compatible with legacy wave-solder and manual assembly |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy body with cathode band marking. Cathode terminal is marked by a colored band; anode is unmarked lead.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-voltage return path; establishes reference for clamping action |
| Cathode | High-side transient sink | Connected to protected line (e.g., 100 V bus); conducts surge current to ground during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Stable VBR tolerance (±5%) and <1 µA leakage over lifetime and temperature cycling |
| 1500 W peak pulse rating | Supports single-event surge currents up to 11.0 A (10/1000 µs) without degradation |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during fast transients-critical for MOSFET gate protection |
| RoHS & halogen-free | Complies with IEC 61249-2-21; enables use in automotive and industrial products with strict material restrictions |
| DO-201 mechanical robustness | UL 94V-0 molding compound and JESD201 Class 2 whisker resistance ensure long-term solder joint reliability |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Lower PPPM (600 W), smaller SMB package (surface-mount), VC = 165 V @ 3.6 A | Not suitable for 1500 W surge events; limited to lower-energy IEC 61000-4-2/4-4 testing | Select when board space is constrained and surge threat level is ≤Level 3 (2 kV/12 Ω) |
| 1N6295A | Same manufacturer, identical electrical specs and DO-201 package; obsolete JEDEC part number for 1V5KE100A | No functional difference; used interchangeably in legacy BOMs and distributor stock | Prefer 1V5KE100A for new designs due to active manufacturing status and updated halogen-free compliance |
Compared with SMBJ100A and 1N6295A, the 1V5KE100A provides higher surge robustness in the same axial package while maintaining backward compatibility with legacy 1N6295A designs-enabling drop-in upgrades for enhanced reliability without layout change.

FAQ
What is the maximum clamping voltage of the 1V5KE100A under a 10/1000 µs surge?
The 1V5KE100A has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 11.0 A under the standard 10/1000 µs waveform. This value is guaranteed per the manufacturer's electrical specifications table and defines the upper voltage limit imposed on protected circuitry during surge events. The 1V5KE100A maintains this clamping performance across its full operating temperature range.
Is the 1V5KE100A unidirectional or bidirectional?
The 1V5KE100A is a unidirectional TVS diode, intended for DC or polarity-defined applications where the protected line remains at positive potential relative to ground. Its cathode band marking indicates the high-side terminal. For bidirectional protection (e.g., AC lines or differential buses), the CA-suffixed variant 1V5KE100CA must be used instead of the 1V5KE100A.
What is the reverse leakage current of the 1V5KE100A at its rated stand-off voltage?
At its reverse stand-off voltage (VRWM) of 85.5 V and ambient temperature of 25°C, the 1V5KE100A exhibits a maximum reverse leakage current (IR) of 5 µA. Typical values are well below 1 µA, ensuring minimal power loss and no measurable impact on high-impedance sensing or battery-backed circuits.
Can the 1V5KE100A be used in place of the older 1N6295A?
Yes-the 1V5KE100A is the direct replacement for the JEDEC-standard 1N6295A, sharing identical electrical parameters, DO-201 packaging, and pinout. Taiwan Semiconductor introduced the 1V5KE100A as a modernized version with updated halogen-free materials and RoHS compliance, while maintaining full form-fit-function equivalence with the 1N6295A.
What is the junction temperature rating of the 1V5KE100A?
The 1V5KE100A has a maximum junction temperature (TJMAX) of +175°C and a minimum of -55°C, enabling reliable operation in demanding thermal environments such as under-hood automotive electronics or enclosed industrial power converters. Its glass-passivated junction ensures parameter stability across this full range.
