Product details
Overview
1V5KE36CA from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in DO-201 package, designed for high-energy surge clamping in power and signal lines. It features a 34.2–37.8 V breakdown voltage (VBR), 30.8 V reverse stand-off voltage (VRWM), 49.9 V clamping voltage (VC) at 30.1 A peak pulse current, and 1500 W peak pulse power rating at 1 ms. It protects industrial I/O interfaces against ESD and lightning-induced transients.
For engineers reviewing the 1V5KE36CA datasheet, 1V5KE36CA pinout, 1V5KE36CA application, or 1V5KE36CA equivalent, key selection criteria include bidirectional clamping symmetry, low clamping ratio (VC/VRWM ≈ 1.62), sub-1 μA leakage above 10 V, and DO-201 mechanical compatibility with legacy PCB footprints.
Technical Context
The 1V5KE36CA operates as a silicon avalanche diode with glass-passivated junction, enabling fast response (<1 ns) to transient overvoltages. Its bidirectional structure provides symmetrical clamping in both polarities without external polarity management, making it suitable for AC-coupled or floating signal paths.
It delivers 1500 W peak pulse power at 1 ms per JEDEC standard, with thermal derating to 5 W continuous power at 75°C ambient. The device maintains stable VBR across -55°C to +175°C operating junction temperature range and exhibits low incremental surge resistance for consistent clamping performance under repetitive surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V - defines guaranteed avalanche conduction onset window under 1 mA test current |
| VRWM | 30.8 V - maximum continuous reverse voltage before significant leakage begins |
| VC @ IPPM | 49.9 V at 30.1 A - clamped voltage during 1 ms 1500 W surge, critical for downstream IC survivability |
| PPPM | 1500 W - peak pulse power handling capability per 1 ms waveform, defining surge energy limit |
| IR @ VRWM | <1 μA - ensures negligible standby current in always-on protection circuits |
| TJ max | +175°C - enables operation in high-temperature environments such as motor drives and power supplies |
| Package | DO-201 - industry-standard axial-leaded package with 0.090 g mass and UL 94V-0 molding compound |
Pinout & Package
1V5KE36CA uses the DO-201 axial package with two terminals: anode and cathode. Polarity is marked by a cathode band on the body; for bidirectional operation, either terminal may serve as input or return path depending on transient polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during negative transients | Conducts when voltage at this terminal falls ≥VBR below cathode potential |
| Cathode | Current entry point during positive transients | Conducts when voltage at this terminal rises ≥VBR above anode potential |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures long-term reliability and stable VBR under humidity and thermal cycling stress |
| 1500 W peak pulse power (1 ms) | Supports IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge immunity without cascaded protection stages |
| Low clamping ratio (VC/VRWM = 1.62) | Minimizes overvoltage exposure to protected ICs while maintaining margin above VRWM |
| Bidirectional symmetry | Eliminates need for polarity-aware layout or external series components in AC or differential lines |
| RoHS & halogen-free compliance | Meets IPC-J-STD-609 and IEC 61249-2-21 requirements for green manufacturing |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA (Bourns) | Same VRWM (36 V), lower PPPM (600 W), SMB package (surface-mount) | Requires PCB redesign for SMT footprint; better suited for space-constrained consumer electronics | Select when board area is limited and surge threat level is ≤IEC 61000-4-5 Level 3 |
| P6KE36CA (ON Semiconductor) | Identical VRWM, VBR, VC, and DO-201 package; 1000 W PPPM rating | Lower energy handling limits use in high-surge industrial environments where 1500 W margin is required | Choose only if legacy design validation already covers P6KE36CA and surge testing confirms adequacy |
Compared with SMBJ36CA and P6KE36CA, the 1V5KE36CA offers superior 1500 W surge capacity in the proven DO-201 through-hole format-critical for industrial field equipment where mechanical robustness and repeatable clamping under extreme transients are non-negotiable.

FAQ
What is the clamping voltage of the 1V5KE36CA under a 1500 W surge?
The 1V5KE36CA clamps to 49.9 V at its rated peak pulse current of 30.1 A, corresponding to a 1500 W surge under the standardized 1 ms exponential waveform. This value is measured per JEDEC test conditions and guarantees maximum voltage seen by downstream circuitry during worst-case transient events.
Is the 1V5KE36CA unidirectional or bidirectional?
The 1V5KE36CA is a bidirectional TVS diode, indicated by the "CA" suffix. It provides symmetrical avalanche breakdown in both polarities, enabling protection of AC signals, differential buses, or floating nodes without polarity constraints-unlike unidirectional variants ending in "A".
What package does the 1V5KE36CA use, and is it RoHS compliant?
The 1V5KE36CA uses the DO-201 axial-leaded package with pure tin-plated leads compliant with J-STD-002 solderability standards. It is fully RoHS compliant and halogen-free per IEC 61249-2-21, with UL 94V-0 rated molding compound and JESD201 Class 2 whisker resistance.
How does the 1V5KE36CA compare to the P6KE36CA in terms of surge capability?
The 1V5KE36CA delivers 1500 W peak pulse power versus 1000 W for the P6KE36CA-50% higher energy handling-while sharing identical VRWM, VBR, and DO-201 packaging. This makes the 1V5KE36CA preferable for applications subject to severe lightning-induced surges or repetitive industrial transients.
Can the 1V5KE36CA be used in automotive applications?
Yes, the 1V5KE36CA is qualified for automotive body electronics applications including BCM I/O and LIN bus protection. Its -55°C to +175°C operating junction temperature range, robust DO-201 mechanical construction, and compliance with ISO 7637-2 pulse tests make it suitable for under-hood and cabin modules where thermal and surge resilience are critical.
