Product details
Overview
1V5KE160CA 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 1500W peak pulse power rating (1ms), 136V reverse standoff voltage (VRWM), 152–168V breakdown voltage (VBR @ 1mA), 219V clamping voltage (VC @ 6.8A), and operates across –55°C to +175°C junction temperature.
For engineers reviewing the 1V5KE160CA datasheet, 1V5KE160CA pinout, 1V5KE160CA application, or 1V5KE160CA equivalent, key selection criteria include clamping performance under 10/1000μs surges, low incremental surge resistance, fast response time (<1ps), and compatibility with ESD/EFT immunity requirements in industrial power supplies and automotive subsystems.
Technical Context
The 1V5KE160CA is a unidirectional/bidirectional avalanche diode optimized for transient suppression using glass-passivated junction technology. Its bipolar construction enables symmetrical clamping in both directions, with guaranteed VBR tolerance of ±5% and IR < 5μA at VRWM.
It meets JEDEC JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards. The device sustains 200A non-repetitive forward surge current (8.3ms half-sine) and derates linearly above 75°C ambient, maintaining 5W steady-state dissipation at 75°C with 0.375" lead length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (1ms) | 1500W - withstands IEC 61000-4-5 Level 4 surges (4kV/2Ω) without failure |
| Reverse Standoff Voltage (VRWM) | 136V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 152–168V @ 1mA - precise avalanche onset range ensures predictable clamping threshold |
| Clamping Voltage (VC) | 219V @ 6.8A - limits downstream voltage during 10/1000μs transients to safe levels |
| Junction Temperature Range | –55°C to +175°C - supports operation in under-hood automotive and industrial motor drive environments |
| Leakage Current (IR) | <5μA @ 136V - minimizes standby power loss and avoids false triggering in high-impedance circuits |
| Package | DO-201 - industry-standard axial-leaded package with tin-plated leads compliant to J-STD-002 |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy-molded body with cathode band marking for unidirectional variants; for 1V5KE160CA (bidirectional), polarity is non-directional - both terminals function identically as symmetrical clamping nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient clamping node | Both terminals connect to protected line and ground (or differential pair); no polarity dependency due to bidirectional design |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable avalanche behavior over 1000+ surge events without parameter drift |
| Low incremental surge resistance | Ensures minimal voltage overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a) |
| Fast response time (<1 ps) | Clamps before sensitive downstream ICs experience overstress - critical for CAN/LIN bus protection |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for green manufacturing |
| UL 94V-0 molding compound | Prevents flame propagation in fault conditions - required for industrial safety certifications |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA (Bourns) | Same 1500W rating, but SMB package (surface-mount); lower clamping voltage (209V vs. 219V) | Requires PCB rework for SMT layout; better for space-constrained designs | Select when automated assembly and board density outweigh axial-lead serviceability needs |
| P6SMB160CA (Littelfuse) | Identical DO-201 package and electrical specs; tighter VBR tolerance (±3.5% vs. ±5%) | No change in circuit design or layout; direct drop-in replacement with enhanced consistency | Preferred for high-volume production where parametric uniformity improves test yield |
Compared with SMBJ160CA and P6SMB160CA, the 1V5KE160CA offers proven axial-leaded reliability in high-vibration environments, lower cost per unit in tape-and-reel, and broader legacy design adoption - making it optimal for industrial retrofit and repair programs where through-hole assembly remains standard.

FAQ
What is the clamping voltage of the 1V5KE160CA under a 10/1000μs surge?
The 1V5KE160CA has a maximum clamping voltage (VC) of 219V at 6.8A peak pulse current under a 10/1000μs waveform. This value is measured per JEDEC standards and guarantees that downstream components see no more than 219V during standardized surge events - essential for protecting 200V-rated electrolytic capacitors and 250V MOSFETs in DC-link applications.
Is the 1V5KE160CA suitable for bidirectional signal line protection?
Yes, the 1V5KE160CA is explicitly rated for bidirectional use (denoted by the "CA" suffix). Its symmetrical VBR (152–168V) and VC characteristics apply equally in both directions, making it appropriate for differential buses like RS-485, CAN FD, or LIN where transients can occur with either polarity relative to ground.
Does the 1V5KE160CA meet automotive qualification standards?
The 1V5KE160CA is not AEC-Q200 qualified out-of-the-box, but Taiwan Semiconductor offers AEC-Q200 versions of the 1V5KE family (e.g., 1V5KE160CAQ) with extended testing. Standard 1V5KE160CA is widely used in non-safety-critical automotive subsystems such as lighting and HVAC controls where its 175°C TJ rating and robust surge handling meet OEM design requirements.
What is the maximum allowable mounting torque for the 1V5KE160CA leads?
Taiwan Semiconductor specifies no explicit lead torque limit for the 1V5KE160CA, but DO-201 axial packages generally tolerate ≤5 in-lb (0.56 N·m) during manual or automated insertion. Exceeding this may crack the epoxy body or dislodge internal wire bonds. For high-vibration applications, potting or mechanical strain relief is recommended to preserve long-term reliability of the 1V5KE160CA.
How does the 1V5KE160CA compare to the 1N6296A in terms of electrical performance?
The 1V5KE160CA and 1N6296A are identical in electrical specification - both correspond to the same JEDEC type (1N6300A) and share identical VRWM (136V), VBR (152–168V), VC (219V), and PPPM (1500W). The "1N6296A" designation is an older JEDEC part number referencing the same device; 1V5KE160CA is Taiwan Semiconductor's proprietary marking for the same 160V bidirectional TVS.
