Product details
Overview
1V5KE400CA 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 a 342 V reverse stand-off voltage (VRWM), 380–420 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (1 ms), 548 V clamping voltage (VC) at 2.8 A IPPM, and operates from –55 °C to +175 °C - used in industrial power supply input protection.
For engineers reviewing the 1V5KE400CA datasheet, 1V5KE400CA pinout, 1V5KE400CA application, or 1V5KE400CA equivalent, key selection criteria include verified clamping performance under 10/1000 µs surges, bi-directional symmetry, DO-201 mechanical compatibility, and compliance with IEC 61000-4-5 Level 4 surge immunity requirements.
Technical Context
The 1V5KE400CA employs a glass-passivated silicon junction for stable avalanche behavior and low incremental surge resistance. Its bi-directional architecture enables symmetrical clamping in AC-coupled or floating systems without polarity concerns.
It delivers 1500 W peak pulse power at 1 ms with fast response time (<1 ns), low leakage (<5 µA at VRWM), and maintains clamping integrity across –55 °C to +175 °C junction temperature range - supporting robust operation in harsh industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 342 V - maximum continuous reverse operating voltage before significant leakage begins |
| VBR (min/max) | 380 V / 420 V at 1 mA - guaranteed avalanche onset range for reliable overvoltage triggering |
| VC @ IPPM | 548 V at 2.8 A - clamped voltage during 10/1000 µs surge, defining protected circuit stress level |
| PPPM | 1500 W - peak surge energy handling capability per JEDEC standard (1 ms pulse) |
| TJ max | +175 °C - maximum junction temperature enabling use in high-ambient industrial enclosures |
| IR @ VRWM | <5 µA - minimal leakage current preserving system standby power integrity |
Pinout & Package
Package: DO-201 - axial-leaded, molded plastic case rated UL 94V-0, with pure tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Polarity marked by cathode band (bi-directional function renders band non-polar in circuit use).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche terminals | No functional polarity - either lead serves as input/output for bidirectional surge suppression |
| Leads (anode & cathode) | PCB mounting and thermal path | 0.375″ lead length supports 5 W steady-state dissipation at 75 °C ambient |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress |
| 1500 W peak pulse power (1 ms) | Withstands IEC 61000-4-5 combination wave surges up to 4 kV open-circuit / 2 kA short-circuit |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., EFT bursts or inductive switch-off) |
| RoHS & halogen-free (IEC 61249-2-21) | Meets global environmental compliance for industrial and automotive-tier supply chains |
Applications
| AC Power Input Protection | Industrial Motor Drive DC Bus |
|---|---|
Use Scenario: Protecting AC-DC front-end rectifiers and bridge modules against lightning-induced surges on mains lines. IC Role / Device Role / Timing Role: Primary clamping device placed across line-to-line or line-to-ground, absorbing >1500 W transient energy. Use Value: Limits voltage to ≤548 V during 10/1000 µs surges, preventing damage to downstream bridge rectifiers and bulk capacitors. | Use Scenario: Safeguarding DC bus rails in variable-frequency drives exposed to regenerative braking spikes. IC Role / Device Role / Timing Role: Bi-directional TVS connected across DC+ and DC– to clamp both positive and negative transients. Use Value: Symmetrical clamping ensures protection during rapid polarity reversal events without requiring dual unidirectional devices. |
| Telecom Line Interface | Renewable Energy Inverter DC Link |
Use Scenario: Surge protection on POTS or DSL line interfaces subject to induced transients from nearby power lines. IC Role / Device Role / Timing Role: First-stage protector before integrated line interface ICs (e.g., SLICs or transceivers). Use Value: Low leakage (<5 µA) preserves line impedance integrity while clamping to safe levels for downstream analog front-ends. | Use Scenario: DC link overvoltage suppression in solar inverters during grid fault recovery or islanding events. IC Role / Device Role / Timing Role: Parallel-connected TVS across high-voltage DC bus (e.g., 600–1000 V systems) to absorb switching transients. Use Value: High VRWM (342 V) allows placement on intermediate bus stages without false triggering during normal operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ400CA (Bourns) | Same DO-214AA package; lower PPPM (600 W); VRWM = 342 V; VC = 548 V at 1.1 A | Limited to lower-energy surges; requires parallel staging for 1500 W-level protection | Select when board space constraints favor SMC/SMB footprint over axial DO-201 |
| P6SMB400CA (Littelfuse) | DO-214AA package; identical VRWM (342 V), VBR (380–420 V), and VC (548 V); same 1500 W rating | Drop-in replacement in SMC layout; different thermal profile due to surface-mount vs. axial leaded construction | Choose for automated assembly where through-hole insertion is unavailable |
Compared with 1V5KE400CA, SMBJ400CA offers smaller footprint but reduced surge capacity, while P6SMB400CA matches electrical specs exactly but shifts thermal management to PCB copper - requiring careful pad design for equivalent 1500 W pulse handling.

FAQ
What is the clamping voltage of the 1V5KE400CA under a 10/1000 µs surge?
The 1V5KE400CA has a maximum clamping voltage (VC) of 548 V when subjected to a 10/1000 µs surge waveform at its rated peak pulse current of 2.8 A. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream components remain within safe operating voltage margins.
Is the 1V5KE400CA unidirectional or bi-directional?
The 1V5KE400CA is a bi-directional TVS diode, indicated by the "CA" suffix. Its electrical characteristics - including breakdown voltage, clamping voltage, and leakage - apply identically in both directions. This eliminates polarity concerns during PCB layout and enables symmetric protection in AC-coupled or floating systems without requiring orientation verification.
What package does the 1V5KE400CA use, and what are its mechanical highlights?
The 1V5KE400CA uses the DO-201 axial-leaded package with UL 94V-0 rated molding compound, pure tin-plated leads compliant with J-STD-002, and JESD 201 Class 2 whisker resistance. Its 0.375″ lead length supports 5 W steady-state dissipation at 75 °C ambient, and the cathode band marking remains visible despite bi-directional functionality.
Does the 1V5KE400CA meet RoHS and halogen-free requirements?
Yes, the 1V5KE400CA is RoHS compliant and halogen-free per IEC 61249-2-21. These certifications are confirmed in the official Taiwan Semiconductor datasheet (Version D2112) and support compliance in industrial, automotive, and consumer electronics supply chains where material restrictions apply.
What is the maximum junction temperature rating for the 1V5KE400CA?
The 1V5KE400CA has a maximum junction temperature (TJ max) of +175 °C, allowing reliable operation in high-ambient environments such as enclosed industrial drives, outdoor telecom cabinets, and solar inverter enclosures. This rating is validated per JEDEC test conditions and supports long-term stability under sustained thermal stress.
