Product details
Overview
1.5KE160HE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-side overvoltage protection in power rails and signal lines. It features a 160 V breakdown voltage (VBR = 152–168 V at 1 mA), 136 V maximum working voltage (VWM), clamps to ≤219 V at 6.8 A peak pulse current, and delivers 1500 W peak pulse power with 10/1000 µs waveform - used in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1.5KE160HE3/73 datasheet, 1.5KE160HE3/73 pinout, 1.5KE160HE3/73 application, or 1.5KE160HE3/73 equivalent, this part serves as a high-energy, AEC-Q101-qualified transient suppressor for DC power line surge immunity per ISO 7637-2 and IEC 61000-4-5, with verified thermal resistance (RθJL = 15.4 °C/W) and low clamping ratio (VC/VBR ≈ 1.36).
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below VWM (136 V), avalanches sharply at VBR (min 152 V), and limits transient voltage to ≤219 V during 1500 W pulses. Its glass-passivated junction ensures stable breakdown and low leakage (<1 µA at VWM).
Designed for single-pulse and repetitive surge suppression, it supports 200 A non-repetitive forward surge (IFSM), withstands 175 °C junction temperature, and exhibits 0.108 %/°C VBR temperature coefficient - enabling predictable clamping across automotive (-40 to +125 °C ambient) and industrial operating ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 152–168 V at 1 mA - defines precise avalanche initiation threshold for reliable overvoltage detection |
| Working Peak Reverse Voltage VWM | 136 V - maximum continuous DC or RMS voltage before leakage exceeds 1 µA |
| Clamping Voltage VC | ≤219 V at 6.8 A (10/1000 µs) - limits downstream circuit stress during surge events |
| Peak Pulse Power PPPM | 1500 W - sustains high-energy transients such as load dump or lightning-induced surges |
| Junction-to-Lead Thermal Resistance RθJL | 15.4 °C/W - enables effective heat dissipation through PCB copper pour or lead frame without heatsink |
| Operating Temperature Range | -55 °C to +175 °C - supports under-hood automotive and high-temp industrial environments |

Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V vehicle battery-fed ECUs against load dump transients up to 120 V for 400 ms. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between power rail and chassis ground to clamp surges before they reach LDOs or microcontrollers. Use Value: Limits peak voltage to ≤219 V during 1500 W pulses, preventing gate oxide rupture in downstream MOSFETs and ICs. |
Use Scenario: Shielding 4–20 mA current-loop sensors in factory automation from induced lightning surges on long cable runs. IC Role / Device Role / Timing Role: Bidirectional-capable but used unidirectionally across sensor supply and return to absorb common-mode transients. Use Value: Sub-nanosecond response time ensures clamping occurs before sensitive op-amps or ADCs experience overvoltage damage. |
| Telecom DC Power Feeds | Consumer Appliance Motor Drive Inputs |
Use Scenario: Safeguarding PoE-powered network switches and base stations from AC-line coupled surges entering via DC input. IC Role / Device Role / Timing Role: Primary-stage TVS on 48 V DC input rail, coordinated with upstream MOVs and downstream π-filters. Use Value: 136 V VWM allows margin above nominal 48 V while maintaining low leakage (<1 µA), minimizing standby power loss. |
Use Scenario: Suppressing commutation spikes from universal motor brushes in washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Mounted across motor terminals or rectifier output to clamp inductive kickback before reaching bridge rectifiers. Use Value: 200 A IFSM rating handles repetitive 8.3 ms half-sine surges without degradation, supporting >100,000-cycle appliance lifetimes. |
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-E3/52 | Lower PPPM (600 W), smaller SMB package (lower IPPM = 3.4 A), same VBR range | Best for space-constrained PCBs where 1500 W is not required; lacks AEC-Q101 qualification | Select when board area is critical and surge energy is limited to IEC 61000-4-5 Level 2 |
| 1.5KE160A-E3/54 | Same electrical specs but commercial-grade (non-AEC-Q101); identical DO-201AD package and pinout | Acceptable for industrial controls or consumer gear where automotive qualification is unnecessary | Choose for cost-sensitive designs without automotive reliability mandates |
Compared with 1.5KE160HE3/73, SMBJ160A-E3/52 trades peak power and qualification for footprint reduction, while 1.5KE160A-E3/54 retains full electrical compatibility but omits AEC-Q101 validation - making the HE3/73 uniquely suited for production automotive systems requiring traceable qualification evidence.

FAQ
What is the clamping voltage of the 1.5KE160HE3/73 at its rated peak pulse current?
The 1.5KE160HE3/73 clamps to a maximum of 219 V when subjected to its specified peak pulse current of 6.8 A using the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and reflects worst-case voltage seen by downstream circuitry during surge events - a critical parameter for ensuring safe operation of protected ICs and MOSFETs.
Is the 1.5KE160HE3/73 suitable for automotive applications?
Yes, the 1.5KE160HE3/73 is AEC-Q101 qualified and explicitly rated for automotive use. Its HE3 suffix confirms compliance with JESD 201 Class 2 whisker testing and full AEC-Q101 stress qualification, making it appropriate for engine control units, body electronics, and ADAS power supplies where reliability under thermal cycling and vibration is mandatory.
How does the 1.5KE160HE3/73 differ from the 1.5KE160A-E3/54?
The 1.5KE160HE3/73 and 1.5KE160A-E3/54 share identical electrical specifications and DO-201AD packaging, but only the HE3/73 carries AEC-Q101 qualification. The "HE3" suffix denotes enhanced reliability screening including high-temperature reverse bias and temperature cycling tests required for automotive deployment - whereas the "A-E3/54" version is commercial-grade.
What is the maximum working voltage (VWM) for the 1.5KE160HE3/73?
The maximum working voltage (VWM) for the 1.5KE160HE3/73 is 136 V. This is the highest DC or RMS voltage that can be continuously applied without exceeding 1 µA reverse leakage current. It provides a 12 V margin below the minimum breakdown voltage (152 V), ensuring stable blocking behavior in 120 V nominal systems like commercial vehicle battery architectures.
Does the 1.5KE160HE3/73 have polarity marking, and how is it identified?
Yes, the 1.5KE160HE3/73 is unidirectional and features a color band (typically black or dark gray) on the cathode end of the axial package. The banded end must be connected toward the higher-potential side of the protected line (e.g., +12 V rail), while the anode connects to ground or return - correct orientation is essential for proper clamping function and surge diversion.
