Product details
Overview
1V5KE8V2CA 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 breakdown voltage of 7.79–8.61 V at 10 mA test current, 12.1 V clamping voltage at 124 A peak pulse current, 1500 W peak pulse power (1 ms), and ≤1 μA reverse leakage at 7.02 V standoff voltage.
For engineers reviewing the 1V5KE8V2CA datasheet, 1V5KE8V2CA pinout, 1V5KE8V2CA application, or 1V5KE8V2CA equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VBR ≈ 1.47), DO-201 mechanical compatibility, and compliance with IEC ESD/IEC EFT immunity requirements for industrial and automotive front-end protection.
Technical Context
The 1V5KE8V2CA operates as a silicon avalanche diode with glass-passivated junction, enabling fast response (<1 ns) to transients and stable clamping under repetitive surge conditions. Its bidirectional symmetry ensures identical electrical behavior in both polarities, eliminating polarity-sensitive layout constraints.
Designed for unclamped inductive switching and lightning-induced surges, it delivers 124 A peak pulse current (10/1000 µs waveform) while maintaining 12.1 V clamping voltage - critical for protecting 5 V and 3.3 V logic interfaces without overvoltage stress on downstream ICs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.79 V / 8.61 V at 10 mA - defines precise avalanche initiation window for predictable clamping onset |
| VRWM | 7.02 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 12.1 V at 124 A - clamping voltage limiting transient energy delivered to protected circuit |
| PPPM | 1500 W (1 ms) - peak surge power handling capacity per JEDEC standard |
| IR @ VRWM | <1 µA - ensures negligible standby current in battery-powered or low-power systems |
| TJ max | 175 °C - enables reliable operation in under-hood automotive or industrial ambient environments |
| Package | DO-201 - industry-standard axial-leaded package with UL 94V-0 molding compound and tin-plated leads |
Pinout & Package
DO-201 package: axial-leaded, cylindrical body with cathode band marking for unidirectional variants; for 1V5KE8V2CA (bi-directional), polarity marking is non-functional - terminals are symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either lead serves as input/output terminal - no polarity dependency in circuit placement |
| Leads (tin-plated) | PCB interface and thermal path | Solderable per J-STD-002; 0.375" lead length supports 5 W steady-state dissipation at 75 °C ambient |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures long-term stability of VBR and low parameter drift across temperature and lifetime |
| 1500 W peak pulse power (1 ms) | Withstands IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge events without degradation |
| Clamping ratio (VC/VBR) ≈ 1.47 | Minimizes overvoltage margin required for protected ICs - reduces need for additional series impedance |
| RoHS & halogen-free (IEC 61249-2-21) | Complies with global environmental regulations and enables use in consumer and automotive supply chains |
| Low incremental surge resistance | Supports consistent clamping performance across multiple surge events without thermal runaway |
Applications
| Industrial PLC I/O Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: Protecting 24 V DC digital input channels against load dump and inductive kickback from solenoids and relays. IC Role / Device Role: Primary surge clamp placed between field wiring and input buffer IC (e.g., TI SN74LVC1G17). Use Value: Limits transient voltage to ≤12.1 V, preventing latch-up or gate oxide damage in 5 V tolerant input buffers. | Use Scenario: Safeguarding LIN bus transceivers and microcontroller GPIOs from ESD (±8 kV contact) and EFT (±2 kV) in door modules. IC Role / Device Role: Bidirectional TVS placed across LIN line-to-ground and VCC-to-ground nodes. Use Value: Symmetrical clamping ensures equal protection during positive/negative transients without polarity-aware routing. |
| AC-DC Power Supply Input Stage | Smart Lighting Driver EMI Filter Interface |
Use Scenario: Secondary-side surge suppression on 12 V DC output rails feeding LED drivers or sensors. IC Role / Device Role: Clamp device located after bulk capacitor and before DC-DC converter input. Use Value: Absorbs 1500 W surges without forward conduction - avoids false triggering of upstream OVP circuits. | Use Scenario: Transient suppression at EMI filter input of DALI or 0–10 V dimmable LED drivers exposed to building wiring noise. IC Role / Device Role: First-line protection before common-mode choke and X/Y capacitors. Use Value: Low VRWM (7.02 V) allows integration into low-voltage control signal paths without affecting 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 |
|---|---|---|---|
| SMBJ8.0CA (Bourns) | Same DO-214AA package; 8.0 V nominal VRWM, 13.6 V VC @ 103 A; 600 W rating | Lower power rating limits use to sub-IEC Level 3 surges; surface-mount only | Select when board space is constrained and surge energy is ≤600 W |
| P6KE8.2CA (ON Semiconductor) | DO-15 package; identical VBR range (7.79–8.61 V); same 1500 W rating but higher VC (12.6 V) | Larger DO-15 footprint; slightly higher clamping increases stress on protected ICs | Choose if DO-15 is already standardized in legacy designs and VC margin permits |
Compared with SMBJ8.0CA and P6KE8.2CA, the 1V5KE8V2CA offers superior power density in DO-201 form factor, tighter clamping voltage, and axial-leaded ease of prototyping - making it optimal for high-reliability 24 V industrial and automotive harness interfaces where leaded robustness matters.

FAQ
What is the exact breakdown voltage range for 1V5KE8V2CA?
The 1V5KE8V2CA has a guaranteed breakdown voltage (VBR) range of 7.79 V to 8.61 V at 10 mA test current, measured per JEDEC standard. This tight tolerance ensures consistent clamping behavior across production lots and supports precise system-level overvoltage margin design without derating overhead.
Is 1V5KE8V2CA unidirectional or bidirectional?
The "CA" suffix in 1V5KE8V2CA explicitly denotes a bi-directional configuration. Unlike "A"-suffixed unidirectional variants, the 1V5KE8V2CA provides symmetrical clamping in both polarities - confirmed by identical VBR, VC, and IPPM specifications for positive and negative surges.
What is the clamping voltage of 1V5KE8V2CA at its rated peak pulse current?
At its rated peak pulse current of 124 A (10/1000 µs waveform), the 1V5KE8V2CA clamps to a maximum of 12.1 V. This value is measured under standardized test conditions and represents the upper limit of voltage seen by protected circuitry during worst-case surge events.
Can 1V5KE8V2CA be used in place of 1N6269A?
Yes - 1V5KE8V2CA is the Taiwan Semiconductor equivalent of the legacy 1N6269A (manufactured by ON Semiconductor). Both share identical electrical specifications, DO-201 packaging, and bidirectional functionality, making 1V5KE8V2CA a direct replacement with full functional and mechanical compatibility.
Does 1V5KE8V2CA meet automotive qualification standards?
The 1V5KE8V2CA is not AEC-Q200 qualified, but its 175 °C maximum junction temperature, robust DO-201 construction, and proven performance in IEC 61000-4-5 and ISO 7637-2 surge testing make it widely deployed in non-safety-critical automotive subsystems such as body electronics and lighting control - subject to customer validation.
