Product details
Overview
1V5KE150CA from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in DO-201 package, rated for 1500W peak pulse power at 1.0ms, with breakdown voltage 143–158V, clamping voltage 207V at 7.2A, and reverse stand-off voltage 128V. It protects power rails and signal lines in industrial motor drives and telecom power supplies against ESD and lightning-induced surges.
For engineers reviewing the 1V5KE150CA datasheet, 1V5KE150CA pinout, 1V5KE150CA application, or 1V5KE150CA equivalent, key selection criteria include verified clamping performance at 7.2A IPPM, bidirectional surge handling per IEC 61000-4-2/4-5, DO-201 mechanical compatibility, and RoHS/halogen-free compliance for high-reliability PCB assembly.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under transient overvoltage exceeding its breakdown threshold (143–158V), it avalanches rapidly to limit voltage across protected circuitry to ≤207V. Its glass-passivated junction ensures stable leakage (<5μA at 128V) and low incremental surge resistance for consistent clamping.
Designed for unidirectional and bidirectional configurations (CA suffix denotes bidirectional), it meets JEDEC JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements. The device sustains 200A non-repetitive forward surge (8.3ms half-sine) only in unidirectional variants - not applicable to 1V5KE150CA due to its bidirectional construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (1ms) | 1500W - sustains single 1ms transients up to this energy without failure |
| Breakdown Voltage VBR | 143–158V @ 1mA - defines minimum voltage at which avalanche conduction begins |
| Clamping Voltage VC | 207V @ 7.2A IPPM - maximum voltage seen by protected circuit during specified surge |
| Reverse Stand-off Voltage VRWM | 128V - maximum continuous DC or RMS voltage before significant leakage |
| Junction Temperature Range | −55°C to +175°C - supports operation in harsh industrial environments |
| Package | DO-201 - axial-leaded, through-hole mountable package with 0.090g mass and tin-plated leads |
| RoHS & Halogen-Free | Compliant per IEC 61249-2-21 - meets environmental regulations for commercial and industrial use |
Pinout & Package
DO-201 package: axial-leaded, cylindrical body with cathode band marking polarity. Bidirectional operation means both terminals are functionally symmetric; no anode/cathode distinction applies for surge suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (marked end) | Surge current entry (bidirectional) | Terminal accepts transient current in either direction; cathode band indicates conventional polarity reference only |
| Cathode (unmarked end) | Surge current exit (bidirectional) | Functionally identical to anode under bidirectional operation; no DC bias dependency |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable leakage current (<5μA at VRWM) and long-term reliability under thermal cycling |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD <1ns rise time) |
| Fast response time | Sub-nanosecond turn-on enables protection of high-speed interfaces and microcontroller I/O |
| UL 94V-0 molding compound | Prevents flame propagation in fault conditions, required for industrial safety certifications |
| Pure tin-plated leads | Guarantees solderability per J-STD-002 and eliminates lead-free assembly compatibility issues |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ150CA | Same DO-214AC package; 1500W rating; VBR = 143–158V; VC = 207V @ 7.2A - identical electrical specs | Identical bidirectional clamping behavior; same IEC 61000-4-2/4-5 compliance level | Drop-in replacement if DO-214AC footprint is preferred; requires PCB layout change from DO-201 |
| ON Semiconductor 1.5KE150CA | Same DO-201 package; identical VBR, VC, and PPPM ratings; RoHS-compliant but halogen content not specified | Same mechanical fit and surge capability; slightly higher typical IR (≤10μA vs. ≤5μA at VRWM) | Direct form-fit-function replacement with identical mounting and thermal profile |
Compared with SMAJ150CA and 1.5KE150CA, the 1V5KE150CA offers guaranteed halogen-free construction per IEC 61249-2-21 and tighter IR specification (<5μA), making it preferable for environmentally regulated industrial and medical-adjacent designs where material compliance is audited.

FAQ
What is the maximum clamping voltage of the 1V5KE150CA under standard test conditions?
The 1V5KE150CA has a maximum clamping voltage (VC) of 207V when subjected to a 7.2A peak pulse current (IPPM) with a 10/1000μs waveform. This value is measured per JEDEC standards and represents the upper voltage limit imposed on protected circuitry during surge events, ensuring downstream components remain within safe operating limits.
Is the 1V5KE150CA suitable for bidirectional surge protection?
Yes, the 1V5KE150CA is explicitly designed for bidirectional transient suppression, as indicated by the "CA" suffix. Its symmetrical breakdown characteristics (VBR = 143–158V in both directions) allow it to protect AC-coupled lines, differential buses, and floating power rails without polarity concerns - unlike unidirectional variants such as 1V5KE150A.
What package type does the 1V5KE150CA use, and what are its key mechanical features?
The 1V5KE150CA uses the DO-201 axial-leaded package, featuring pure tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 flammability-rated molding compound, and JEDEC JESD201 Class 2 whisker resistance. Its 0.090g mass and standardized lead spacing support automated through-hole assembly and thermal dissipation in high-power layouts.
Does the 1V5KE150CA meet RoHS and halogen-free requirements?
Yes, the 1V5KE150CA is RoHS compliant and halogen-free per IEC 61249-2-21. This dual certification ensures compatibility with stringent environmental regulations in EU, China, and North American markets, and supports safer end-of-life processing without release of corrosive halogen gases during board recycling or incineration.
What is the reverse leakage current specification for the 1V5KE150CA at its rated VRWM?
At its reverse stand-off voltage (VRWM) of 128V and TA = 25°C, the 1V5KE150CA exhibits a maximum reverse leakage current (IR) of 5μA. This low leakage ensures minimal power loss in standby mode and prevents unintended biasing of sensitive analog circuits connected to the same rail.
