Product details
Overview
1.5KE160C-E3/73 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), 136 V maximum standoff voltage (VWM), 219 V clamping voltage at 6.8 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the 1.5KE160C-E3/73 datasheet, 1.5KE160C-E3/73 pinout, 1.5KE160C-E3/73 application, or 1.5KE160C-E3/73 equivalent, this page delivers verified electrical parameters, JEDEC-standard 1.5KE package details, bidirectional clamping behavior, thermal derating curves, and direct alternative part comparisons for ESD and lightning transient design validation.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering sub-nanosecond response time (<1 ns) and low incremental surge resistance to clamp fast transients induced by inductive switching or lightning surges. Its bidirectional architecture enables symmetrical clamping across both polarities without external polarity management.
Rated for -55 °C to +175 °C junction temperature, it supports high-reliability applications with 75 °C/W junction-to-ambient thermal resistance and complies with JESD22-B106 solder dip (275 °C, 10 s). The E3 suffix confirms RoHS compliance and JESD201 Class 1A whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 152 V / 168 V - ensures reliable avalanche conduction onset within defined tolerance band under 1 mA test current |
| VWM | 136 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 219 V - clamped voltage during 1500 W transient, limiting downstream component stress |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | DO-214AA package (smaller footprint), 1500 W rating, VBR = 178–197 V, VC = 259 V @ 5.8 A | Higher clamping voltage and lower IPPM; suited for space-constrained PCBs where thermal mass is limited | Select SMBJ160CA when board area is constrained and 259 V clamping is acceptable for downstream voltage margin |
| SMCJ160CA | DO-214AB package, 1500 W rating, VBR = 178–197 V, VC = 259 V @ 5.8 A, RθJA = 35 °C/W | Lower thermal resistance enables higher duty-cycle operation; larger footprint than 1.5KE but smaller than axial leaded alternatives | Choose SMCJ160CA for improved thermal performance in high-ambient-temperature industrial enclosures |
Compared with 1.5KE160C-E3/73, SMBJ160CA trades lower mounting height for higher clamping voltage, while SMCJ160CA offers superior thermal dissipation in compact surface-mount form - neither is pin-compatible, but all three deliver 1500 W surge protection at ~160 V standoff.

FAQ
What is the breakdown voltage range of the 1.5KE160C-E3/73?
The 1.5KE160C-E3/73 has a specified breakdown voltage (VBR) range of 152 V to 168 V at 1 mA test current, measured per JEDEC standard. This tolerance band ensures consistent clamping onset across production lots and supports reliable design margining against overvoltage events in 136 V nominal systems.
Is the 1.5KE160C-E3/73 unidirectional or bidirectional?
The 1.5KE160C-E3/73 is a bidirectional TVS diode, indicated by the "C" suffix. It provides symmetrical clamping for both positive and negative transients without polarity marking on the package - ideal for AC-coupled lines, differential buses, and floating ground systems where voltage reversal occurs.
What does the "E3/73" suffix mean in 1.5KE160C-E3/73?
The "E3" denotes RoHS compliance and JESD201 Class 1A whisker resistance; "/73" specifies packaging in 73 mm tape-and-reel format (1400 pcs per reel). This configuration ensures compatibility with automated SMT placement and meets environmental and reliability requirements for commercial-grade deployments.
Can the 1.5KE160C-E3/73 replace a unidirectional 1.5KE160A-E3/73 in circuit design?
No - the 1.5KE160C-E3/73 is bidirectional and lacks cathode marking, while the 1.5KE160A-E3/73 is unidirectional with polarity-dependent clamping. Substitution requires verifying system-level polarity constraints, grounding topology, and transient directionality; direct replacement may compromise protection in DC-biased rails.
What is the maximum clamping voltage of the 1.5KE160C-E3/73 under surge conditions?
The 1.5KE160C-E3/73 exhibits a maximum clamping voltage (VC) of 219 V at its rated peak pulse current (IPPM = 6.8 A) using the 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events and must be validated against downstream component absolute maximum ratings.
