Overview
1.5KE16C-E3/54 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 protection, industrial I/O interfaces, and telecom line surge suppression.
For engineers reviewing the 1.5KE16C-E3/54 datasheet, 1.5KE16C-E3/54 pinout, 1.5KE16C-E3/54 application, or 1.5KE16C-E3/54 equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, JEDEC 1.5KE package details, thermal derating curves, and direct alternatives with documented parameter differences.
Technical Context
This TVS diode operates in bidirectional mode with symmetrical clamping in both polarities, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, critical for consistent clamping under repetitive transients.
Designed for 10/1000 µs waveform compliance, it delivers 66.7 A peak pulse current (IPPM) while maintaining clamping voltage ≤22.5 V - a key requirement for safeguarding 3.3 V and 5 V logic interfaces against ESD and lightning-induced surges per IEC 61000-4-5.
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 | DO-214AA package (smaller footprint), 600 W PPPM, VC = 26.0 V @ 24.9 A | Lower power rating; suited for space-constrained PCBs where 1500 W is not required | Select SMBJ16CA when board area is limited and surge threat level is ≤IEC 61000-4-5 Level 3 (2 kV) |
| 1.5SMC16CA | SMD DO-214AB package, same 1500 W rating, VC = 26.0 V @ 58.1 A, higher thermal resistance (RθJA = 110 °C/W) | Surface-mount alternative requiring reflow-compatible layout; less effective heat dissipation in high ambient | Choose 1.5SMC16CA only if through-hole mounting is unavailable and thermal management via copper pour is implemented |
Compared with 1.5KE16C-E3/54, SMBJ16CA trades peak power and clamping tightness for compactness, while 1.5SMC16CA retains power rating but sacrifices thermal performance and requires SMT assembly - making 1.5KE16C-E3/54 optimal for high-reliability through-hole designs needing proven 1500 W surge handling.

FAQ
What is the breakdown voltage tolerance of the 1.5KE16C-E3/54?
The 1.5KE16C-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 calculations for protected circuits. The 1.5KE16C-E3/54 maintains this specification per Vishay Document 88301, Revision 09-Aug-2022.
Is the 1.5KE16C-E3/54 suitable for automotive applications?
Yes, the 1.5KE16C-E3/54 is qualified to AEC-Q101 when ordered with the HE3 suffix (e.g., 1.5KE16CAHE3_B), but the E3/54 variant is commercial grade. Its −55 °C to +175 °C operating junction temperature range, glass-passivated junction, and 1500 W surge capability make it technically suitable for under-hood and chassis-mounted applications - however, for production automotive use, the AEC-Q101-qualified version must be selected. The 1.5KE16C-E3/54 itself meets all electrical and thermal specs needed for such roles.
How does the clamping voltage of the 1.5KE16C-E3/54 compare to its breakdown voltage?
The 1.5KE16C-E3/54 clamps to ≤22.5 V at its rated peak pulse current of 66.7 A (10/1000 µs waveform), which is approximately 41% above its minimum breakdown voltage of 15.2 V. This VC–VBR margin reflects the device's low dynamic impedance and ensures protected circuitry remains within safe voltage limits during fast-rising transients. That relationship is fixed per the datasheet and applies identically in both directions due to its bidirectional symmetry.
What is the maximum reverse leakage current for the 1.5KE16C-E3/54 at its working voltage?
At its maximum stand-off voltage (VWM) of 13.6 V, the 1.5KE16C-E3/54 exhibits ≤1.0 µA reverse leakage current at 25 °C, per Vishay Document 88301. This ultra-low leakage preserves signal integrity in high-impedance analog paths and minimizes standby power loss in battery-operated systems. Leakage remains below 5 µA up to +125 °C, ensuring stable performance across industrial temperature ranges.
Can the 1.5KE16C-E3/54 be used in bidirectional AC signal protection?
Yes - the "C" suffix in 1.5KE16C-E3/54 explicitly denotes bidirectional configuration, meaning it provides symmetrical clamping for both positive and negative transients without polarity sensitivity. This makes it ideal for protecting AC-coupled interfaces like telecom lines, audio inputs, or differential data buses where voltage excursions occur in either direction. No external biasing or orientation is required, and the 1.5KE16C-E3/54 performs identically across both polarities per its datasheet specifications.
