Product details
Overview
1.5KE62CA-T from Diodes Incorporated is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, designed for high-energy surge protection in DC power rails and signal lines. It features a 53.0V reverse standoff voltage, 58.9–65.1V breakdown range at 1mA, 85.0V max clamping voltage at 17.7A peak pulse current, and operates from –55°C to +175°C.
For engineers reviewing the 1.5KE62CA-T datasheet, 1.5KE62CA-T pinout, 1.5KE62CA-T application, or 1.5KE62CA-T equivalent, this device serves as a robust overvoltage clamp for automotive power systems, industrial I/O interfaces, and telecom line protection where fast response (<1 ns), low leakage (<5 µA @ 53.0V), and stable temperature coefficient (0.104%/°C) are critical.
Technical Context
This bidirectional TVS diode uses glass-passivated silicon junctions to achieve sub-nanosecond response time and consistent clamping performance across temperature. Its symmetrical avalanche structure enables equal protection for positive and negative transients without polarity dependency.
The device is rated for 1500W peak pulse power (10/1000 µs waveform), with steady-state dissipation of 5.0W at 75°C lead temperature. Its 0.104%/°C voltage temperature coefficient ensures predictable clamping behavior under thermal stress in engine bay or industrial control environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | 600W rating, SMB package, 64V VRWM, 104V VC @ 5.8A | Lower power handling; surface-mount only; unsuitable for high-energy load dump | Select when board space is constrained and surge energy is limited to IEC 61000-4-5 Level 2 |
| 1.5SMC68CA | 1500W rating, SMC package, 68V VRWM, 110V VC @ 13.6A | Higher clamping voltage (110V vs. 85V); larger footprint; higher thermal resistance | Choose only if 68V standoff matches system nominal voltage and layout allows SMC body size |
Compared with SMBJ64CA and 1.5SMC68CA, the 1.5KE62CA-T delivers superior clamping ratio (85.0V/53.0V = 1.60) and axial-leaded mechanical robustness for through-hole mounting in high-vibration environments, while maintaining identical 1500W surge capability.

FAQ
What does the "CA" suffix indicate in 1.5KE62CA-T?
The "C" denotes bidirectional configuration, meaning the device provides symmetrical clamping for both positive and negative transients. The "A" indicates standard tolerance (±5% on breakdown voltage). This differs from unidirectional "A" variants, which require correct polarity installation and feature a cathode band marking.
Is 1.5KE62CA-T suitable for IEC 61000-4-5 surge testing?
Yes - its 1500W peak pulse rating (10/1000 µs waveform) and 85.0V clamping voltage at 17.7A meet the energy and voltage limits required for IEC 61000-4-5 Level 4 (4 kV) testing in industrial and automotive equipment, provided PCB layout minimizes inductance in the protection path.
How does the DO-201 package affect thermal performance?
The DO-201 axial package has higher thermal resistance than surface-mount alternatives (e.g., SMC), but its 9.5 mm lead length at TL = 75°C supports 5.0W steady-state dissipation. For pulsed operation, thermal mass and lead conduction dominate - making it well-suited for infrequent, high-energy transients rather than repetitive duty cycles.
Why is the 1.5KE62CA-T marked without a cathode band?
Bidirectional TVS diodes like the 1.5KE62CA-T lack polarity-dependent function, so no cathode band is applied. The device is marked with "1.5KE62CA" only, confirming symmetrical junction behavior - critical for AC-coupled or floating applications where orientation cannot be assumed during assembly.
