Product details
Overview
P6KE15CA-E3/73 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features a 15 V breakdown voltage (VBR min/max = 14.3–15.8 V), 12.8 V stand-off voltage (VWM), 21.2 V maximum clamping voltage at 28.3 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE15CA-E3/73 datasheet, P6KE15CA-E3/73 pinout, P6KE15CA-E3/73 application, or P6KE15CA-E3/73 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification status (not applicable to E3 suffix), and verified 21.2 V clamping performance under 28.3 A transient surge.
Technical Context
This device operates as a voltage-clamped shunt protector: when reverse (or forward, in bidirectional mode) voltage exceeds VBR, it avalanches to limit transient energy. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 μA at 12.8 V), while thermal resistance RθJL = 20 °C/W enables reliable power dissipation up to 5.0 W on infinite heatsink.
The P6KE15CA-E3/73 exhibits symmetric conduction in both polarities, with identical VBR, VC, and IPPM specifications in either direction. Its response time is sub-nanosecond, and it complies with UL 497B for protector classification (QVGQ2), supporting use in safety-critical signal line protection where bidirectional surges - such as ESD or inductive switching spikes - occur unpredictably.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.3 V / 15.8 V - defines precise avalanche initiation threshold for reliable clamping onset |
| VWM | 12.8 V - maximum continuous working voltage before leakage rises above 1.0 μA |
| VC @ IPPM | 21.2 V @ 28.3 A - clamped voltage during 10/1000 μs surge, directly limiting downstream component stress |
| PPPM | 600 W - peak transient power handling capacity, enabling robust protection against lightning or load dump events |
| IPPM | 28.3 A - maximum non-repetitive surge current the device safely clamps without failure |
| TJ max | +175 °C - extended junction temperature range supports operation in under-hood automotive or high-ambient industrial environments |
| Package | DO-15 (DO-204AC) - industry-standard axial leaded package with 0.242–0.258 inch body length, compatible with legacy through-hole assembly |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; no polarity marking - bidirectional symmetry means both terminals are functionally identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient shunt path | Either terminal conducts during overvoltage in either polarity; no cathode band marking required |
| Leads (both) | Thermal and electrical interface | Provide mechanical mounting, heat conduction to PCB copper, and low-inductance connection to protected line |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | DO-214AA package, 1.5 kW peak power, lower RθJA (50 °C/W), same VBR/VC specs | Suitable for higher-density SMT layouts; not axial-compatible | Select SMBJ15CA when board space is constrained and reflow assembly is used. |
| P6KE15A-E3/73 | Unidirectional variant; includes cathode band marking; identical VBR, VC, and package | Required only where polarity-specific clamping is needed (e.g., DC supply rails) | Choose P6KE15A-E3/73 if protecting a unidirectional 12 V rail with explicit cathode orientation. |
Compared with SMBJ15CA and P6KE15A-E3/73, the P6KE15CA-E3/73 provides cost-effective, through-hole bidirectional protection in legacy DO-15 footprint - ideal for service replacement, low-volume industrial controls, or designs requiring mechanical robustness over SMT miniaturization.

FAQ
What is the clamping voltage of P6KE15CA-E3/73 at its rated peak pulse current?
The P6KE15CA-E3/73 has a maximum clamping voltage (VC) of 21.2 V when subjected to its rated peak pulse current of 28.3 A using the standard 10/1000 μs waveform. This value is measured under defined test conditions per JEDEC standards and ensures predictable voltage limiting during surge events. The P6KE15CA-E3/73 maintains this clamping performance symmetrically in both directions due to its bidirectional construction.
Is P6KE15CA-E3/73 AEC-Q101 qualified?
No, the P6KE15CA-E3/73 is RoHS-compliant and rated for commercial-grade operation; AEC-Q101 qualification applies only to variants with the HE3 suffix (e.g., P6KE15CAHE3/73). The E3 suffix indicates JESD201 Class 1A whisker testing and UL 94 V-0 molding compound, but does not include automotive stress qualification. For automotive applications requiring AEC-Q101, specify the HE3 version of P6KE15CA-E3/73.
What is the stand-off voltage (VWM) of P6KE15CA-E3/73, and why does it matter?
The stand-off voltage (VWM) of P6KE15CA-E3/73 is 12.8 V - the maximum continuous DC or RMS voltage the device can withstand without exceeding 1.0 μA reverse leakage current. This parameter ensures the P6KE15CA-E3/73 remains non-conductive during normal circuit operation while remaining ready to avalanche instantly upon transient overvoltage. Selecting VWM ≥110 % of operating voltage prevents nuisance conduction.
Can P6KE15CA-E3/73 replace P6KE15A-E3/73 in a design?
P6KE15CA-E3/73 cannot be a direct drop-in replacement for P6KE15A-E3/73 in unidirectional applications because it lacks polarity marking and conducts identically in both directions - potentially causing unintended conduction on DC rails. However, in AC-coupled, floating, or bidirectional signal paths (e.g., data lines), the P6KE15CA-E3/73 offers functional equivalence with simplified layout. Always verify circuit topology before substitution.
What package type does P6KE15CA-E3/73 use, and what are its key mechanical dimensions?
P6KE15CA-E3/73 uses the DO-15 (DO-204AC) axial-leaded package with a cylindrical epoxy body measuring 0.242–0.258 inch (6.15–6.55 mm) in length and 0.130–0.138 inch (3.3–3.5 mm) in diameter. Leads are matte tin-plated and solderable per J-STD-002; the package meets UL 94 V-0 flammability rating. This standardized footprint ensures compatibility with existing through-hole tooling and manual repair workflows.
