Product details
Overview
1.5KE160C-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 160 V breakdown voltage (VBR = 152–168 V), 1500 W peak pulse power (10/1000 µs), clamping voltage of 219 V at 6.8 A, and operates from −55 °C to +175 °C - used to protect MOSFETs, ICs, and sensor interfaces in industrial motor drives and telecom power supplies.
For engineers reviewing the 1.5KE160C-E3/54 datasheet, 1.5KE160C-E3/54 pinout, 1.5KE160C-E3/54 application, or 1.5KE160C-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping performance under standardized transients, and direct alternatives with documented voltage and power differences.
Technical Context
This device is a glass-passivated, unidirectional/bidirectional silicon avalanche diode optimized for transient suppression per IEC 61000-4-5 and ANSI/IEEE C62.35 standards. Its bidirectional configuration enables symmetrical clamping on AC-coupled or floating lines without polarity concerns.
It delivers 1500 W peak pulse power with a 10/1000 µs waveform at 0.01% duty cycle, exhibits <1 ns response time, and maintains low incremental surge resistance - critical for limiting voltage overshoot during lightning-induced surges or inductive switching events in 48 V DC systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 152 V / 168 V - ensures reliable avalanche conduction onset within ±5% tolerance at 1 mA test current |
| VWM | 136 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |
| VC @ IPPM | 219 V - clamped voltage seen by protected circuit when subjected to full 6.8 A transient current |
| PPPM | 1500 W - peak surge energy absorption capability under standardized 10/1000 µs waveform |
| IPPM | 6.8 A - maximum non-repetitive peak pulse current supported at rated clamping voltage |
| TJ max. | +175 °C - junction temperature limit enabling operation in high-ambient environments like automotive engine bays |
| Package | JEDEC DO-201AD (1.5KE) - axial-leaded, epoxy-molded case rated UL 94 V-0, compatible with wave soldering |

| 1500 W peak pulse power (10/1000 µs) | Supports EN 61000-4-5 Level 4 (4 kV) surge immunity testing on 50 Ω source impedance |
| Clamping ratio VC/VBR ≈ 1.37 | Minimizes overvoltage stress on downstream components compared to MOVs or polymer-based suppressors |
| Response time < 1 ns | Engages before most semiconductor failure mechanisms initiate - protects gate oxides and ESD-sensitive inputs |
| Operating TJ up to +175 °C | Validates use in under-hood automotive modules and industrial power converters without derating |
Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ160CA | Same 160 V VBR, but 400 W PPPM (SMA package); lower clamping voltage (224 V @ 1.8 A) | Lower energy handling limits use to sub-1 kV transients; unsuitable for IEC 61000-4-5 Level 4 | Select when space-constrained layouts require SMD mounting and surge energy is ≤400 W |
| ON Semiconductor 1.5SMC160CA | Same 160 V VBR, 1500 W PPPM, but SMC (DO-214AB) package; slightly higher VC (230 V @ 6.5 A) | SMD footprint eliminates axial lead routing; thermal resistance differs due to package geometry | Choose for automated assembly and where board real estate favors surface-mount over through-hole |
Compared with 1.5KE160C-E3/54, SMAJ160CA offers smaller size but only 27% of the surge energy rating, while 1.5SMC160CA matches power capability in an SMD form - making the latter a drop-in functional alternative for reflow-compatible designs requiring identical clamping robustness.

FAQ
What is the breakdown voltage range for the 1.5KE160C-E3/54?
The 1.5KE160C-E3/54 has a guaranteed breakdown voltage (VBR) range of 152 V to 168 V at 1 mA test current, measured per ANSI/IEEE C62.35. This tight ±5% tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margin design in 136 V nominal systems.
Is the 1.5KE160C-E3/54 unidirectional or bidirectional?
The 1.5KE160C-E3/54 is a bidirectional Transient Voltage Suppressor, indicated by the "C" suffix. It provides symmetrical clamping in both polarities - no cathode marking, no polarity sensitivity - making it ideal for AC-coupled lines, differential buses, or floating power domains where voltage reversal may occur.
What is the maximum clamping voltage of the 1.5KE160C-E3/54 under surge conditions?
The 1.5KE160C-E3/54 clamps to a maximum of 219 V when subjected to its rated peak pulse current of 6.8 A (10/1000 µs waveform). This value is measured per JEDEC standard test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Does the 1.5KE160C-E3/54 meet automotive qualification standards?
The base 1.5KE160C-E3/54 is commercial-grade and not AEC-Q101 qualified. However, Vishay offers the variant 1.5KE160CHE3_B (with HE3 suffix) which is AEC-Q101 qualified - confirmed in Document Number 88301, Note (2) - for automotive under-hood and body electronics applications.
What package type does the 1.5KE160C-E3/54 use, and is it RoHS compliant?
The 1.5KE160C-E3/54 uses the JEDEC DO-201AD (1.5KE) axial-leaded package with molded epoxy body and matte tin-plated leads. It is RoHS compliant per JESD 201 Class 1A whisker test, as indicated by the "E3" suffix and confirmed in Vishay Document 88301, Mechanical Data section.
