Product details
Overview
1.5KE16CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in signal and power lines. It features a 16 V breakdown voltage (VBR = 15.2–16.8 V at IT = 1.0 mA), 13.6 V stand-off voltage (VWM), 22.5 V maximum clamping voltage (VC) at 66.7 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5KE16CA-E3/54 datasheet, 1.5KE16CA-E3/54 pinout, 1.5KE16CA-E3/54 application, or 1.5KE16CA-E3/54 equivalent, this device delivers verified bidirectional clamping performance, RoHS-compliant matte tin-plated leads, UL 94 V-0 molded epoxy packaging, and AEC-Q101 qualification eligibility - critical for ESD and lightning surge hardening in safety-critical embedded systems.
Technical Context
This TVS diode operates symmetrically in both polarities due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, while the 10/1000 µs waveform response supports compliance with IEC 61000-4-5 Level 3 surge immunity requirements.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15.4 °C/W, supporting reliable operation up to TJ = +175 °C. The device exhibits <1 ns response time and clamps transients before downstream ICs experience damaging overvoltage - confirmed via standardized 8/20 µs and 10/1000 µs impulse testing per ANSI/IEEE C62.35.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | Lower PPPM (600 W), smaller SMB package (surface-mount), higher VC (26.0 V @ 38.8 A) | Preferred for space-constrained PCBs where 1500 W rating is not required | Select when board area is limited and surge threat level is ≤IEC 61000-4-5 Level 2 |
| 1.5SMC16CA | Same 1500 W rating but SMC (DO-214AB) package, slightly higher VC (25.0 V @ 60.0 A), lower thermal resistance (RθJA ≈ 50 °C/W) | Better suited for high-density layouts requiring surface-mount assembly and improved thermal performance | Choose for automated SMT production and enhanced thermal management in compact enclosures |
Compared with 1.5KE16CA-E3/54, SMBJ16CA trades peak power and axial-lead robustness for footprint reduction, while 1.5SMC16CA retains full 1500 W capability in a more thermally efficient surface-mount form - making the latter ideal for modern industrial drives and the former optimal for legacy through-hole designs requiring mechanical durability.

FAQ
What is the breakdown voltage tolerance for 1.5KE16CA-E3/54?
The 1.5KE16CA-E3/54 has a specified breakdown voltage range of 15.2 V to 16.8 V at 1.0 mA test current, representing a ±5% tolerance around the nominal 16 V rating. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes, directly supporting design margin verification for 12 V system interfaces. The value is measured per JEDEC standard test conditions and documented in Vishay's 88301 datasheet.
Is 1.5KE16CA-E3/54 suitable for automotive applications?
Yes - the 1.5KE16CA-E3/54 is eligible for AEC-Q101 qualification when ordered with the HE3 suffix (e.g., 1.5KE16CAHE3_B). While the E3/54 variant is commercial-grade, its –55 °C to +175 °C operating range, glass-passivated junction, and 1500 W surge capability align with automotive subsystem requirements including body control modules and sensor front-ends. Designers should specify the HE3 version for production automotive programs requiring formal qualification evidence.
How does the clamping voltage of 1.5KE16CA-E3/54 compare to similar 16 V TVS diodes?
The 1.5KE16CA-E3/54 clamps to 22.5 V at 66.7 A (10/1000 µs), which is among the lowest VC/VBR ratios in the 1.5KE family. This compares favorably to alternatives like SMBJ16CA (26.0 V @ 38.8 A) and 1.5SMC16CA (25.0 V @ 60.0 A), offering superior protection margin for 16 V rail systems. The low incremental clamping voltage results from optimized junction geometry and low dynamic resistance, verified in Vishay's Fig. 7–10 curves.
What is the lead finish and solderability specification for 1.5KE16CA-E3/54?
The 1.5KE16CA-E3/54 features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. The E3 suffix confirms JESD 201 Class 1A whisker resistance, and the device supports solder dip at 275 °C for up to 10 seconds per JESD 22-B106. These specifications ensure reliable through-hole assembly in high-volume manufacturing and compatibility with lead-free reflow profiles when used with appropriate flux chemistry.
Can 1.5KE16CA-E3/54 be used in bidirectional AC signal paths?
Yes - the "CA" suffix explicitly denotes bidirectional functionality, meaning 1.5KE16CA-E3/54 provides symmetrical clamping in both polarities with identical VBR, VWM, and VC characteristics. This makes it ideal for protecting AC-coupled analog signals, RS-485 differential pairs, and transformer-isolated power rails where polarity reversal occurs. No external biasing or orientation constraints apply, simplifying layout and eliminating risk of reverse installation.
