Product details
Overview
1V5KE160A from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with breakdown voltage 152–168 V at 1 mA test current, reverse stand-off voltage 136 V, clamping voltage 219 V at 6.8 A peak pulse current, and junction temperature range −55°C to +175°C. It protects power rails and I/O lines against ESD, lightning surges, and inductive switching transients in industrial power supplies and motor drives.
For engineers reviewing the 1V5KE160A datasheet, 1V5KE160A pinout, 1V5KE160A application, or 1V5KE160A equivalent, key selection criteria include clamping ratio (VC/VRWM ≈ 1.61), low leakage (<5 µA at 136 V), fast response time (<1.0 ps), and compliance with IEC 61000-4-2 Level 4 (±15 kV air/±8 kV contact).
Technical Context
The 1V5KE160A operates as a silicon avalanche diode, triggered when reverse voltage exceeds its specified breakdown threshold (VBR = 152–168 V). Its glass-passivated junction ensures stable avalanche characteristics and low incremental surge resistance (ZPP ≈ 32.2 Ω, derived from VC/IPPM = 219 V / 6.8 A).
Designed for single-pulse transient suppression per 10/1000 µs waveform, it delivers 1500 W peak pulse power at 1 ms, with derating to 5 W steady-state power at 75°C lead temperature. Polarity is marked by cathode band; bidirectional variant is 1V5KE160CA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 136 V - Maximum continuous reverse operating voltage before significant leakage begins |
| VBR @ IT=1 mA | 152–168 V - Avalanche breakdown voltage range defining turn-on threshold under standardized test |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A (Bourns) | Same VRWM (136 V), same DO-214AA package, but lower PPPM = 600 W | Limited to lower-energy transients (e.g., ESD-only); unsuitable for IEC 61000-4-5 line surges | Select 1V5KE160A when 1500 W pulse handling is required; SMBJ160A fits space-constrained PCBs needing only ESD-level protection |
| 1N6296A (ON Semiconductor) | Identical electrical specs (VRWM, VBR, VC, PPPM) and DO-201 package; RoHS-compliant | No functional difference; validated drop-in replacement per ON's datasheet revision 1.2 | 1N6296A offers second-source availability with identical performance-ideal for dual-sourcing strategies in long-lifecycle programs |
Compared with SMBJ160A and 1N6296A, the 1V5KE160A provides full 1500 W surge capacity in DO-201, unlike the 600 W SMBJ160A, while matching 1N6296A's performance exactly-making it optimal for high-energy industrial transients where second-source assurance matters.

FAQ
What is the breakdown voltage range of the 1V5KE160A?
The 1V5KE160A has a guaranteed breakdown voltage (VBR) range of 152 V to 168 V at 1 mA test current, measured per JEDEC standard. This range reflects process tolerance and ensures consistent turn-on behavior across production lots. The 1V5KE160A's tight VBR spread supports predictable clamping performance in safety-critical surge protection circuits.
Is the 1V5KE160A unidirectional or bidirectional?
1V5KE160A is a unidirectional TVS diode, designed to conduct only in reverse avalanche mode. Its cathode band marks the polarity-sensitive terminal. For bidirectional operation, the equivalent part is 1V5KE160CA, which provides symmetrical clamping in both directions and is used in AC-coupled or floating signal line protection.
What is the clamping voltage of the 1V5KE160A at its rated peak pulse current?
The 1V5KE160A clamps to 219 V at its rated peak pulse current of 6.8 A (10/1000 µs waveform). This value is measured under standardized conditions and defines the maximum voltage imposed on protected circuitry during a full-energy transient. The 1V5KE160A's clamping ratio (VC/VRWM = 219/136 ≈ 1.61) is tighter than industry average, improving protection margin.
Does the 1V5KE160A meet RoHS and halogen-free requirements?
Yes, the 1V5KE160A is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. This makes the 1V5KE160A suitable for export to EU, China, and other regulated markets requiring green material declarations.
What is the maximum junction temperature rating for the 1V5KE160A?
The 1V5KE160A has a maximum junction temperature (TJ) rating of +175°C and a minimum of −55°C. This wide thermal range enables reliable operation in under-hood automotive applications, industrial inverters, and outdoor power equipment. Derating curves confirm 5 W steady-state power dissipation at 75°C lead temperature.
