Product details
Overview
1V5KE130CA from Taiwan Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-201 package, designed for high-energy surge clamping in power and signal lines. It features 1500W peak pulse power (1ms), 124–137V breakdown voltage (VBR), 111V reverse stand-off voltage (VRWM), 8.4A peak pulse current (IPPM), and 179V clamping voltage (VC) - deployed in industrial power supplies and telecom interface protection.
For engineers reviewing the 1V5KE130CA datasheet, 1V5KE130CA pinout, 1V5KE130CA application, or 1V5KE130CA equivalent, key selection considerations include bipolar clamping symmetry, low incremental surge resistance, sub-1μA leakage at 111V, RoHS/halogen-free compliance, and DO-201 mechanical robustness for high-reliability PCB mounting.
Technical Context
The 1V5KE130CA operates as a bi-directional avalanche diode with symmetrical VBR (124–137V) and identical electrical characteristics in both polarities. Its glass-passivated junction ensures stable breakdown behavior under repetitive transients, while its low dynamic impedance enables effective clamping of fast-rising EFT and lightning-induced surges.
Rated for 175°C maximum junction temperature and compliant with JESD201 Class 2 whisker resistance, the device supports operation across –55°C to +175°C ambient. It delivers 1500W peak pulse power at 1ms (10/1000μs waveform) with typical reverse leakage <1μA above 111V, meeting IEC 61000-4-2/4-4/4-5 immunity requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 124V / 137V - defines guaranteed avalanche conduction onset range under 1mA test current |
| VRWM | 111V - maximum continuous reverse voltage before significant leakage begins |
| VC @ IPPM | 179V - clamped voltage during 8.4A 1ms surge, limiting downstream stress |
| IPPM | 8.4A - peak surge current capability at rated 1500W, 1ms pulse |
| PPPM | 1500W - peak pulse power handling per JEDEC standard, critical for lightning strike immunity |
| TJ(max) | +175°C - enables use in high-temperature environments like enclosed power converters |
| Package | DO-201 - axial-leaded, UL 94V-0 molded case with tin-plated leads per J-STD-002 |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy body with cathode band marking for polarity identification. Bi-directional operation means no functional anode/cathode distinction - terminals are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Surge input terminal | Accepts transient energy in either polarity; connected to protected line (e.g., RS-485 A/B) |
| Cathode (Lead 2) | Surge input terminal | Electrically identical to Lead 1 in bi-directional mode; forms symmetrical clamping path |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable, repeatable avalanche breakdown without degradation under repeated surges |
| 1500W peak pulse power (1ms) | Withstands IEC 61000-4-5 Level 4 (4kV/2Ω) surges without failure |
| Low incremental surge resistance | Minimizes VC overshoot during fast transients, improving system-level clamping margin |
| RoHS & halogen-free (IEC 61249-2-21) | Meets global environmental compliance for industrial and telecom equipment manufacturing |
| Bi-directional symmetry | Eliminates need for orientation-aware placement on differential lines like CAN or RS-485 |
Applications
| Industrial Power Input Protection | RS-485 Data Line Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | DO-214AA (SMB) package; lower 600W PPPM; 130V VRWM, 219V VC | Higher clamping voltage reduces protection margin; smaller footprint but lower surge rating | Select when board space is constrained and surge threat level is ≤IEC 61000-4-5 Level 3 |
| 1N6297A | Same manufacturer, identical DO-201 package and 120V rating group; VRWM = 102V, VC = 165V | Lower clamping voltage improves protection margin but requires higher VIN derating | Choose for tighter clamping where 165V VC allows use of 175V-rated downstream components |
Compared with SMBJ130CA and 1N6297A, the 1V5KE130CA offers superior 1500W surge handling in the proven DO-201 form factor, balancing clamping performance (179V), thermal robustness (+175°C), and legacy compatibility - making it optimal for high-reliability industrial and telecom infrastructure designs.

FAQ
What is the breakdown voltage range of the 1V5KE130CA?
The 1V5KE130CA has a specified breakdown voltage (VBR) range of 124V to 137V at 1mA test current, measured in both directions due to its bi-directional construction. This range ensures reliable, repeatable avalanche conduction onset across production lots and operating temperatures, supporting consistent clamping behavior in high-voltage surge protection circuits.
Is the 1V5KE130CA unidirectional or bidirectional?
The 1V5KE130CA is a bi-directional TVS diode, indicated by the "CA" suffix. Its electrical characteristics - including VBR, VRWM, and VC - apply identically in both polarities. This eliminates orientation sensitivity during PCB assembly and makes it ideal for protecting differential signal lines such as RS-485, CAN, or telecom interfaces.
What is the clamping voltage of the 1V5KE130CA at its rated peak pulse current?
The 1V5KE130CA clamps to a maximum of 179V at its rated peak pulse current of 8.4A (IPPM) under a 1ms, 10/1000μs waveform. This VC value is critical for determining the voltage stress imposed on downstream components and must be compared against their absolute maximum ratings to ensure survivability during surge events.
Does the 1V5KE130CA meet RoHS and halogen-free requirements?
Yes, the 1V5KE130CA is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound and lead finish (pure tin plating) satisfy environmental regulations for industrial and telecom equipment, enabling global deployment without material compliance concerns or end-of-life substitution pressure.
What package type does the 1V5KE130CA use, and what are its key mechanical attributes?
The 1V5KE130CA uses the DO-201 axial-leaded package: UL 94V-0 rated epoxy body, pure tin-plated leads compliant with J-STD-002 solderability, and JESD201 Class 2 whisker resistance. Its standardized form factor ensures compatibility with legacy through-hole assembly processes and provides robust mechanical anchoring for high-vibration environments.
