Product details
Overview
1.5KE160-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 1500 W peak pulse power rating (10/1000 µs), 136 V standoff voltage (VWM), 152–168 V breakdown voltage (VBR), and clamps to ≤219 V at 6.8 A peak pulse current - deployed in automotive power supply inputs and industrial sensor interface circuits.
For engineers reviewing the 1.5KE160-E3/73 datasheet, 1.5KE160-E3/73 pinout, 1.5KE160-E3/73 application, or 1.5KE160-E3/73 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, thermal derating behavior, clamping performance under surge conditions, and RoHS-compliant commercial-grade sourcing context for ESD and lightning transient suppression design.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: it remains high-impedance below VWM = 136 V and transitions rapidly (<1 ns) into low-impedance conduction above VBR = 152–168 V to divert surge energy away from downstream ICs. Its glass-passivated junction ensures stable breakdown and low leakage (≤1.0 µA at VWM).
Rated for 1500 W peak pulse power (10/1000 µs waveform), it supports repetitive surges at 0.01% duty cycle and withstands 200 A non-repetitive forward surge (8.3 ms half-sine). Thermal resistance is RθJA = 75 °C/W and RθJL = 15.4 °C/W, enabling reliable operation up to TJ = 175 °C with appropriate PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin. |
| VBR @ IT = 1 mA | 152–168 V - Measured breakdown range confirming precise threshold activation for overvoltage events. |
| VC @ IPPM = 6.8 A | ≤219 V - Clamped voltage during full-rated 1500 W surge; determines maximum stress on protected circuitry. |
| PPPM | 1500 W - Peak pulse power handling per 10/1000 µs waveform; validates robustness against IEC 61000-4-5 Level 4 surges. |
| IFSM | 200 A - Non-repetitive forward surge current rating (8.3 ms); supports high-energy inductive switch-off transients. |
| TJ max. | +175 °C - Maximum junction temperature; enables use in under-hood automotive and high-ambient industrial environments. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; guides minimum copper pour area for thermal management. |

Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed between power rail and chassis ground to clamp spikes above 136 V. Use Value: Limits voltage seen by downstream LDOs and MCU power pins to ≤219 V during 1500 W surges, preventing latch-up or gate oxide rupture. | Use Scenario: Safeguarding analog outputs of pressure/temperature sensors connected to PLC analog input modules. IC Role / Device Role / Timing Role: Unidirectional TVS on 4–20 mA loop or 0–10 V output line to absorb field-induced surges. Use Value: Maintains signal integrity by clamping induced transients within 1 ns while adding <1 pF capacitance - no bandwidth degradation. |
| Telecom DC Power Feeds | Consumer Appliance Motor Drive Inputs |
Use Scenario: Overvoltage protection on -48 V DC feeds powering remote radio units and base station controllers. IC Role / Device Role / Timing Role: Primary protection device on input stage, coordinated with upstream fuses and secondary TVS arrays. Use Value: Handles repeated lightning-induced surges per ITU-T K.20/K.21 with verified 1500 W capability and 175 °C thermal endurance. | Use Scenario: Suppressing back-EMF spikes generated by brushed DC motors in washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Mounted across motor terminals or H-bridge supply rails to divert inductive kickback energy. Use Value: Withstands 200 A 8.3 ms surge current and clamps to ≤219 V, preventing MOSFET avalanche failure and controller reset. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A | Lower PPPM (600 W), smaller SMB package (surface-mount), VWM = 150 V, VC = 243 V @ 2.5 A | Better suited for space-constrained PCBs but requires higher layout precision due to lower surge margin. | Select when board area is limited and surge threat level is moderate (IEC 61000-4-5 Level 2–3). |
| 1.5KE150A | Lower VWM (128 V), VBR = 143–158 V, same 1500 W rating and DO-201AD package | Provides tighter clamping margin for 125 V nominal systems but reduces headroom for normal operating transients. | Choose for designs requiring lower clamping voltage where 136 V VWM is excessive relative to system rail. |
Compared with 1.5KE160-E3/73, SMBJ150A trades surge capacity for compactness and surface-mount compatibility, while 1.5KE150A offers lower clamping at the cost of reduced standoff margin - both require revalidation of thermal layout and PCB trace routing.

FAQ
What is the standoff voltage (VWM) of the 1.5KE160-E3/73?
The 1.5KE160-E3/73 has a maximum working standoff voltage (VWM) of 136 V. This value represents the highest continuous reverse voltage the device can block without entering breakdown - essential for ensuring no leakage or false triggering during normal 12 V or 24 V system operation. The 1.5KE160-E3/73 maintains <1.0 µA reverse leakage at this voltage, supporting stable long-term performance in power rail protection roles.
Does the 1.5KE160-E3/73 meet automotive qualification standards?
The 1.5KE160-E3/73 is a commercial-grade part and is not AEC-Q101 qualified. Vishay offers AEC-Q101 versions under the HE3 suffix (e.g., 1.5KE160AHE3_B), but the E3/73 variant carries only RoHS compliance and JESD 201 Class 1A whisker testing. For automotive applications requiring formal qualification, the 1.5KE160-E3/73 must be validated per customer-specific reliability protocols - the 1.5KE160-E3/73 itself does not carry AEC-Q101 certification.
What is the clamping voltage (VC) of the 1.5KE160-E3/73 at its rated peak pulse current?
At its rated peak pulse current of 6.8 A (corresponding to 1500 W with a 10/1000 µs waveform), the 1.5KE160-E3/73 clamps to a maximum of 219 V. This VC value defines the upper voltage limit imposed on protected circuitry during worst-case surge events and is critical for verifying that downstream components - such as 200 V-rated MOSFETs or 24 V LDOs - remain within safe operating limits. The 1.5KE160-E3/73 achieves this with sub-nanosecond response and low incremental surge resistance.
Can the 1.5KE160-E3/73 be used in bidirectional configurations?
No, the 1.5KE160-E3/73 is a unidirectional TVS diode and is not rated for bidirectional operation. Bidirectional variants in the 1.5KE family use the "CA" suffix (e.g., 1.5KE160CA) and are only available up to 1.5KE220CA per Vishay's documentation. Using the 1.5KE160-E3/73 in reverse-biased AC applications would result in forward conduction and potential failure. For bidirectional protection at ~160 V, the 1.5KE160CA - not the 1.5KE160-E3/73 - is the correct selection.
What package type does the 1.5KE160-E3/73 use, and what are its key mechanical properties?
The 1.5KE160-E3/73 uses the JEDEC DO-201AD package (Case Style 1.5KE): an axial-leaded, molded epoxy body measuring 5.3 mm in diameter and 9.5 mm in length, with 7.2 mm lead spacing. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards, and the epoxy compound meets UL 94 V-0 flammability rating. This robust through-hole package provides superior thermal dissipation (RθJL = 15.4 °C/W) compared to SMD alternatives - a key advantage for high-surge industrial deployments where the 1.5KE160-E3/73 is commonly applied.
