Product details
Overview
1V5KE16CA 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 15.2–16.8 V breakdown voltage (VBR), 13.6 V reverse stand-off voltage (VRWM), 22.5 V clamping voltage (VC) at 67 A peak pulse current, and 1500 W peak pulse power rating at 1 ms. It is used to protect industrial I/O ports and DC power rails against ESD and lightning-induced transients.
For engineers reviewing the 1V5KE16CA datasheet, 1V5KE16CA pinout, 1V5KE16CA application, or 1V5KE16CA equivalent, key selection criteria include its bidirectional clamping behavior, low 22.5 V clamping voltage under 67 A surge, DO-201 mechanical compatibility, RoHS/halogen-free compliance, and suitability for 24 V system-level surge immunity per IEC 61000-4-5.
Technical Context
The 1V5KE16CA 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 with low incremental surge resistance, ensuring stable clamping performance across repetitive surges. The device maintains <1 µA reverse leakage above 13.6 V and supports junction temperatures from –55 °C to +175 °C, supporting operation in harsh industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V - defines guaranteed avalanche conduction onset range at 1 mA test current |
| VRWM | 13.6 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 22.5 V at 67 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 power loss and minimal interference in high-impedance circuits |
| TJ max | +175 °C - enables reliable operation in enclosed industrial enclosures or near heat-generating components |
| Package | DO-201 - industry-standard axial-leaded package with 0.090 g mass and UL 94V-0 molding compound |
Pinout & Package
1V5KE16CA uses the DO-201 axial package with two terminals: anode and cathode. Polarity is marked by a band on the cathode end. No internal circuitry or additional pins exist-this is a two-terminal passive device.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal in forward bias; reference node for bidirectional clamping | Connects to line or rail requiring protection; forms symmetrical clamp path with cathode |
| Cathode | Negative terminal in forward bias; marked with band | Provides physical polarity identification; same electrical role as anode in reverse polarity events due to bidirectional design |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable long-term reliability and consistent VBR tolerance under thermal cycling and humidity stress |
| 1500 W peak pulse power (1 ms) | Supports IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge testing on 24 V DC power inputs |
| Low clamping ratio (VC/VRWM = 1.65) | Minimizes overvoltage stress on protected ICs compared to higher-ratio TVS devices |
| RoHS & halogen-free (IEC 61249-2-21) | Meets global environmental compliance requirements for industrial and automotive supply chains |
| DO-201 mechanical standardization | Enables drop-in replacement in legacy designs using JEDEC-standard axial TVS diodes |
Applications
| Industrial PLC Digital I/O Protection | 24 V DC Power Rail Surge Suppression |
|---|---|
Use Scenario: Protecting programmable logic controller (PLC) digital input modules from field-wiring induced transients and ESD. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between signal line and ground, limiting transient excursions to ≤22.5 V. Use Value: Prevents latch-up or permanent damage to input buffer ICs rated for 30 V absolute maximum, extending field-reliability beyond IEC 61000-4-4/5 compliance. | Use Scenario: Safeguarding 24 V DC power distribution networks in factory automation equipment against load-dump and inductive switching spikes. IC Role / Device Role / Timing Role: Parallel-connected surge limiter across power rail and chassis ground, conducting >67 A surges within nanoseconds. Use Value: Maintains rail integrity below 22.5 V during 1500 W transients, preventing brownout resets or regulator failure in downstream SMPS and microcontrollers. |
| RS-485 Transceiver Line Protection | Automotive Body Control Module (BCM) Sensor Interface |
Use Scenario: Shielding RS-485 differential bus lines (A/B) from EFT and surge coupling in building control systems. IC Role / Device Role / Timing Role: Bidirectional TVS pair (one per line) referenced to common ground, clamping common-mode transients. Use Value: Preserves signal integrity by limiting common-mode excursion to 22.5 V, avoiding receiver saturation and data corruption during 1 kV EFT bursts. | Use Scenario: Protecting 5 V sensor inputs (e.g., temperature, pressure) in automotive BCMs exposed to ISO 7637-2 pulse 1/2/5a. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp on sensor signal path, placed close to connector entry point. Use Value: Withstands 100 V/500 ms load dump pulses while maintaining <1 µA leakage, preventing false triggers or ADC offset drift in precision analog front-ends. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | DO-214AA (SMB) package; 16 V VRWM; 25.5 V VC @ 43.5 A; lower 600 W PPPM | Higher clamping voltage and lower surge rating; suited for space-constrained PCBs where 1500 W is not required | Select when board area is limited and surge threat level is ≤IEC 61000-4-5 Level 3 |
| 1N6276A | Same manufacturer, identical electrical specs and DO-201 package; obsolete JEDEC part number superseded by 1V5KE16CA | No functional difference; identical use cases and layout compatibility | Prefer 1V5KE16CA for new designs due to updated halogen-free and RoHS-compliant construction |
Compared with SMBJ16CA and 1N6276A, the 1V5KE16CA offers superior 1500 W surge handling and lower clamping voltage in the same axial form factor, while providing modern environmental compliance absent in the legacy 1N6276A.

FAQ
What is the breakdown voltage range of the 1V5KE16CA?
The 1V5KE16CA has a guaranteed breakdown voltage (VBR) range of 15.2 V to 16.8 V at 1 mA test current, measured per JEDEC standards. This range ensures consistent avalanche initiation across production lots and temperature extremes, directly supporting predictable clamping behavior in 12–24 V system designs.
Is the 1V5KE16CA unidirectional or bidirectional?
The 1V5KE16CA is a bidirectional TVS diode, indicated by the "CA" suffix. It provides symmetrical clamping in both polarities, eliminating the need for polarity-aware placement. This makes it ideal for AC signal lines, floating interfaces, or any application where voltage reversals may occur during transients.
What is the clamping voltage of the 1V5KE16CA at its rated peak pulse current?
The 1V5KE16CA clamps to 22.5 V at its rated peak pulse current of 67 A (1 ms waveform). This value is measured under standardized conditions and represents the maximum voltage seen by protected circuitry during a full 1500 W surge event, a key parameter for validating downstream IC survivability.
Does the 1V5KE16CA meet RoHS and halogen-free requirements?
Yes, the 1V5KE16CA is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound and tin-plated leads satisfy environmental regulations for industrial and automotive supply chains, with full documentation available in TSC's material declarations.
What package type does the 1V5KE16CA use, and what are its mechanical highlights?
The 1V5KE16CA uses the DO-201 axial package with pure tin-plated leads solderable per J-STD-002, UL 94V-0 flammability-rated molding compound, and JESD 201 Class 2 whisker resistance. Its 0.090 g mass and standardized lead spacing support automated insertion and legacy board compatibility.
