Product details
Overview
1V5KE6V8CA from Taiwan Semiconductor is a bi-directional transient voltage suppressor (TVS) diode designed for high-energy surge clamping in power and signal lines. It delivers 1500W peak pulse power at 1.0ms, with a breakdown voltage of 6.45–7.14V (tested at 10mA), reverse stand-off voltage of 5.80V, clamping voltage of 10.5V at 143A, and operates across –55°C to +175°C junction temperature.
For engineers reviewing the 1V5KE6V8CA datasheet, 1V5KE6V8CA pinout, 1V5KE6V8CA application, or 1V5KE6V8CA equivalent, key selection criteria include its DO-201 package, bidirectional polarity marking, sub-1μA leakage above 10V, low incremental surge resistance, and compliance with RoHS and halogen-free IEC 61249-2-21 standards.
Technical Context
The 1V5KE6V8CA is a glass-passivated, junction-based TVS diode optimized for fast response to ESD and electrical fast transients (EFT). Its bi-directional construction enables symmetrical clamping in AC-coupled or floating signal paths without polarity sensitivity.
It features a low clamping ratio (VC/VBR ≈ 1.55), typical IR < 1μA at VRWM = 5.80V, and maintains stable performance under repetitive surges per JEDEC-standard 10/1000μs waveform testing. The device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (1ms) | 1500W - sustains single high-energy surges up to 143A without failure |
| Breakdown Voltage VBR | 6.45–7.14V @ IT = 10mA - defines precise conduction onset for overvoltage protection |
| Reverse Stand-off Voltage VRWM | 5.80V - maximum continuous operating voltage before leakage exceeds 10μA |
| Clamping Voltage VC | 10.5V @ IPPM = 143A - limits downstream voltage stress during surge events |
| Junction Temperature Range | –55°C to +175°C - supports operation in automotive under-hood and industrial power environments |
| Package | DO-201 - axial-leaded, through-hole mountable package with tin-plated leads per J-STD-002 |
| Leakage Current IR | <1μA @ VRWM = 5.80V - minimizes standby power loss in battery-powered systems |
Pinout & Package
1V5KE6V8CA is housed in a DO-201 axial package with two terminals: cathode-marked end (band) and anode. Polarity is marked for uni-directional variants; for bi-directional 1V5KE6V8CA, the band indicates either terminal - no functional polarity distinction exists.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bi-directional surge path | Either terminal accepts transient current in either direction; no DC bias dependency |
| Lead (anode side) | PCB mounting interface | 0.375" lead length supports 5W steady-state dissipation at 75°C ambient |
| Lead (cathode side) | PCB mounting interface | Tin-plated per J-STD-002; passes JESD201 Class 2 whisker test |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable long-term reliability and low parameter drift under thermal cycling |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD > 15kV) |
| Fast response time | Sub-nanosecond turn-on ensures clamping before sensitive ICs experience overstress |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and global environmental regulations for industrial and consumer PCBs |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.8CA | DO-214AA package; 600W rating; VBR = 7.14–7.88V; VC = 11.2V @ 53.3A | Lower power handling; surface-mount only; suited for space-constrained PCBs | Select when board area is limited and surge energy rarely exceeds 600W |
| P6KE6.8CA | DO-15 package; 600W rating; VBR = 6.45–7.14V; VC = 10.5V @ 57A | Same VBR/VC but lower IPPM; legacy through-hole footprint with larger pitch | Choose for backward compatibility with DO-15 layouts where 1500W capability is not required |
Compared with SMBJ6.8CA and P6KE6.8CA, the 1V5KE6V8CA provides 2.5× higher peak pulse power in the same DO-201 form factor, enabling robust protection in high-surge industrial and automotive environments where smaller packages would thermally saturate.

FAQ
What does the "CA" suffix mean in 1V5KE6V8CA?
The "CA" suffix in 1V5KE6V8CA denotes a bi-directional configuration. Unlike uni-directional variants (e.g., 1V5KE6V8A), the 1V5KE6V8CA provides symmetrical clamping in both polarities, making it ideal for AC signal lines, differential buses, or floating grounds where polarity cannot be guaranteed. This is confirmed in TSC's datasheet Version D2112, Section "Devices for Bipolar Applications".
What is the maximum clamping voltage of 1V5KE6V8CA under surge conditions?
The maximum clamping voltage (VC) of 1V5KE6V8CA is 10.5V when subjected to its rated peak pulse current of 143A (10/1000μs waveform). This value is measured per JEDEC standard and ensures downstream components see no more than 10.5V during worst-case transients - critical for protecting 5V logic interfaces and analog front-ends.
Can 1V5KE6V8CA replace P6KE6.8CA in existing designs?
1V5KE6V8CA is not a direct drop-in replacement for P6KE6.8CA due to differences in package (DO-201 vs. DO-15) and mechanical dimensions, though both share identical VBR and VC values. Layout changes are required for lead spacing and board cutouts. However, 1V5KE6V8CA offers 2.5× higher peak power (1500W vs. 600W), making it suitable for upgraded surge robustness where thermal and mechanical constraints allow.
Is 1V5KE6V8CA compliant with RoHS and halogen-free standards?
Yes, 1V5KE6V8CA is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and the pure tin-plated leads comply with J-STD-002 solderability requirements. These qualifications are explicitly stated in the "FEATURES" and "MECHANICAL DATA" sections of the official TSC datasheet (Version D2112).
What is the leakage current specification for 1V5KE6V8CA at its rated VRWM?
At its reverse stand-off voltage (VRWM) of 5.80V, the 1V5KE6V8CA exhibits typical reverse leakage current (IR) of less than 1μA - verified at 25°C per TSC's ELECTRICAL SPECIFICATIONS table. This ultra-low leakage preserves battery life in always-on systems and avoids false triggering in high-impedance sensing circuits.
