Product details
Overview
1.5KE16C-E3/73 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal and power lines. It features a 16 V breakdown voltage (VBR = 15.2–16.8 V at IT = 1.0 mA), 1500 W peak pulse power (10/1000 µs), and clamps to ≤22.5 V at 66.7 A peak pulse current - used in automotive sensor interface protection and industrial I/O line surge suppression.
For engineers reviewing the 1.5KE16C-E3/73 datasheet, 1.5KE16C-E3/73 pinout, 1.5KE16C-E3/73 application, or 1.5KE16C-E3/73 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, bidirectional clamping behavior, thermal derating curves, and RoHS-compliant commercial-grade sourcing support at Aetrix Electronics.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, optimized for fast transient response (<1 ns) and low incremental surge resistance. Its bidirectional structure enables symmetrical clamping in AC-coupled or floating signal paths without polarity concerns.
Rated for -55 °C to +175 °C junction temperature, it supports high-reliability applications with 75 °C/W junction-to-ambient thermal resistance and meets JESD 22-B106 soldering requirements (275 °C, 10 s). The E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | 600 W peak pulse power (vs. 1500 W); SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients; unsuitable for automotive load dump or industrial 4 kV surges | Select when board space is constrained and surge threat level is ≤IEC 61000-4-5 Level 2 |
| 1.5SMC16CA | Same 1500 W rating but SMC package (higher thermal mass, lower RθJA ≈ 35 °C/W) | Better thermal performance for repetitive surge duty cycles; requires larger PCB area | Prefer for high-temperature environments (>105 °C ambient) or frequent transient exposure |
Compared with 1.5KE16C-E3/73, SMBJ16CA offers compact size but sacrifices surge robustness, while 1.5SMC16CA improves thermal management at the cost of footprint - making 1.5KE16C-E3/73 optimal for cost-sensitive, medium-duty commercial applications requiring proven JEDEC 1.5KE reliability.

FAQ
What is the breakdown voltage tolerance for 1.5KE16C-E3/73?
The 1.5KE16C-E3/73 has a specified breakdown voltage range of 15.2 V to 16.8 V at 1.0 mA test current, per Vishay Document 88301. This ±5.3% tolerance ensures consistent clamping behavior across production lots and supports reliable design margining against overvoltage events. The value is measured under controlled conditions and applies to both directions due to its bidirectional construction.
Is 1.5KE16C-E3/73 RoHS compliant and lead-free?
Yes, the 1.5KE16C-E3/73 carries the E3 suffix, which certifies full RoHS compliance and lead-free construction per EU Directive 2011/65/EU. It also meets JESD 201 Class 1A whisker resistance requirements and is qualified for solder reflow up to 275 °C for 10 seconds, ensuring compatibility with standard lead-free assembly processes.
How does the clamping voltage of 1.5KE16C-E3/73 compare to its breakdown voltage?
The 1.5KE16C-E3/73 clamps to a maximum of 22.5 V at its rated peak pulse current of 66.7 A (10/1000 µs waveform), while its breakdown voltage starts at 15.2 V. This 7.3 V differential reflects the device's incremental surge resistance and defines the worst-case overvoltage imposed on protected circuitry - critical for verifying compatibility with 3.3 V or 5 V logic rails.
Can 1.5KE16C-E3/73 be used in place of a unidirectional TVS like 1.5KE16A?
No - the 1.5KE16C-E3/73 is strictly bidirectional and lacks polarity marking, whereas 1.5KE16A is unidirectional with a cathode band. Substituting them requires verifying circuit topology: 1.5KE16C-E3/73 suits AC-coupled, floating, or differential lines; 1.5KE16A is required for DC-biased single-ended paths where forward conduction must be blocked.
What is the maximum operating temperature for 1.5KE16C-E3/73?
The 1.5KE16C-E3/73 has a maximum junction temperature (TJ) of +175 °C and an operating storage range of -55 °C to +175 °C. Its thermal resistance (RθJA = 75 °C/W) means that at 6.5 W steady-state dissipation, ambient temperature must remain below ~125 °C to avoid exceeding TJ max - making it suitable for under-hood automotive or enclosed industrial control applications.
