Product details
Overview
1V5KE7V5CA from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with breakdown voltage 7.13–7.88 V at 10 mA test current, reverse stand-off voltage 6.40 V, clamping voltage 11.3 V at 133 A peak pulse current, and junction temperature range −55°C to +175°C. It protects sensitive ICs and systems against ESD, electrical fast transients, and inductive switching surges.
For engineers reviewing the 1V5KE7V5CA datasheet, 1V5KE7V5CA pinout, 1V5KE7V5CA application, or 1V5KE7V5CA equivalent, key selection criteria include bidirectional clamping performance, 1ms pulse power rating, DO-201 mechanical compatibility, low leakage (<1 µA above 10 V), and RoHS/halogen-free compliance for industrial and lighting systems.
Technical Context
The 1V5KE7V5CA is a junction-controlled, glass-passivated, bidirectional TVS diode designed for unidirectional or bidirectional surge suppression without polarity dependence. Its low incremental surge resistance and fast response time enable effective clamping of sub-microsecond transients while maintaining stable VRWM and tight VBR tolerance (±5% typical).
It operates across −55°C to +175°C junction temperature, supports 200 A single half-sine forward surge (uni-directional only), and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements. The device is rated for 1500 W peak pulse power at 1 ms, with derating above 75°C ambient per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V at IT = 10 mA - defines reliable conduction onset under surge conditions |
| VRWM | 6.40 V - maximum continuous reverse voltage before significant leakage |
| VC @ IPPM | 11.3 V at 133 A - clamped voltage during 1500 W transient, limiting stress on downstream circuitry |
| IR @ VRWM | <1 µA - ensures negligible standby power loss and signal integrity in high-impedance nodes |
| PPPM | 1500 W at Tp = 1 ms - peak surge energy handling capacity per standard waveform |
| TJ Range | −55°C to +175°C - enables deployment in automotive under-hood, industrial motor drives, and outdoor lighting |
| Package | DO-201 - industry-standard axial leaded package with tin-plated leads, UL 94V-0 molding compound |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy body with cathode band marking for unidirectional variants; for 1V5KE7V5CA (bidirectional), polarity marking is non-functional - terminals are symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional surge conduction path | Either terminal serves as anode or cathode depending on transient polarity - no orientation required in PCB layout |
| Leads (both) | PCB mounting and thermal conduction path | Tin-plated, solderable per J-STD-002; lead length ≥0.375″ required for full 5 W steady-state dissipation at 75°C |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR and low leakage over lifetime and temperature cycling |
| 1500 W peak pulse power (1 ms) | Handles high-energy lightning-induced surges per IEC 61000-4-5 Level 4 (4 kV/2 Ω) |
| Clamping voltage 11.3 V @ 133 A | Provides safe margin below 12 V rail IC thresholds while limiting transient overshoot |
| RoHS and halogen-free (IEC 61249-2-21) | Meets global environmental compliance for industrial and consumer end equipment |
| UL 94V-0 molding compound | Prevents flame propagation in fault conditions, critical for lighting and power supply designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0CA (Bourns) | Same DO-214AA package; lower PPPM = 600 W; VBR = 7.78–8.60 V; VC = 12.0 V @ 50 A | Lower surge rating limits use to Class 2/3 IEC 61000-4-5; better suited for space-constrained PCBs | Select when board area is constrained and surge threat level is moderate (e.g., indoor consumer electronics) |
| P6KE7.5CA (Littelfuse) | DO-204AC (DO-15) package; identical 1500 W rating; VBR = 7.13–7.88 V; VC = 12.0 V @ 125 A | Larger body height and different lead spacing; requires PCB footprint revision | Choose when legacy DO-15 footprint exists and thermal mass from longer leads improves reliability in high-temp environments |
Compared with SMBJ7.0CA and P6KE7.5CA, the 1V5KE7V5CA offers optimal balance of high-energy handling (1500 W), tight VC (11.3 V), and DO-201's proven thermal robustness in high-reliability industrial and outdoor applications - without requiring layout changes from other 1.5 kW DO-201 TVS devices.

FAQ
What is the breakdown voltage tolerance of the 1V5KE7V5CA?
The 1V5KE7V5CA has a specified breakdown voltage range of 7.13 V to 7.88 V at 10 mA test current, representing a ±5% tolerance around the nominal 7.5 V rating. This tight VBR distribution ensures consistent clamping behavior across production lots and supports predictable system-level surge margin design without over-engineering.
Is the 1V5KE7V5CA suitable for bidirectional signal line protection?
Yes, the 1V5KE7V5CA is explicitly designed for bidirectional operation, as indicated by the "CA" suffix. Its symmetrical VBR and VC characteristics apply equally in both polarities, making it ideal for protecting differential buses (e.g., RS-485, CAN) or AC-coupled signal paths where transient polarity is unpredictable.
What is the maximum clamping voltage of the 1V5KE7V5CA under surge conditions?
The 1V5KE7V5CA clamps to a maximum of 11.3 V when subjected to its rated 133 A peak pulse current (10/1000 µs waveform). This value is guaranteed per datasheet testing and represents the upper limit of voltage seen by protected circuitry during a full 1500 W transient event.
Does the 1V5KE7V5CA require orientation during PCB placement?
No - the 1V5KE7V5CA is a bidirectional TVS diode with symmetrical terminals. Unlike unidirectional variants (e.g., 1V5KE7V5A), it has no functional cathode marking; either lead may connect to any node in the circuit. The DO-201 body marking is for traceability only and does not indicate polarity.
How does the 1V5KE7V5CA compare to MOV-based protection in terms of response time?
The 1V5KE7V5CA responds in under 1 ns, significantly faster than metal-oxide varistors (MOVs), which typically exhibit 20–50 ns delay. This speed advantage allows the 1V5KE7V5CA to clamp initial transient edges before MOVs activate, providing superior protection for sensitive semiconductor gates and data lines in mixed-protection schemes.
