Product details
Overview
P6KE15CA-E3/54 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 15 V breakdown voltage (VBR min/max = 14.3–15.8 V at 1.0 mA), 12.8 V stand-off voltage (VWM), 21.2 V maximum clamping voltage at 28.3 A peak pulse current (10/1000 μs), and 600 W peak pulse power rating. It protects MOSFETs and ICs in automotive sensor interfaces against inductive switching surges.
For engineers reviewing the P6KE15CA-E3/54 datasheet, P6KE15CA-E3/54 pinout, P6KE15CA-E3/54 application, or P6KE15CA-E3/54 equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, DO-15 mechanical data, thermal derating curves, and AEC-Q101-qualified alternatives for automotive-grade transient protection design.
Technical Context
This bidirectional TVS operates symmetrically in both polarities with identical VBR, VC, and IPPM specifications - no cathode marking required. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing ESD and load-dump transients before downstream components fail.
Rated for 175 °C maximum junction temperature and 5.0 W steady-state power dissipation on infinite heatsink, it supports high-reliability operation in under-hood automotive environments. The device complies with UL 497B (QVGQ2 recognition) and meets JESD 201 Class 1A whisker testing when ordered with E3 suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.3 V / 15.8 V at 1.0 mA test current - defines reliable conduction onset threshold in either polarity |
| VWM | 12.8 V - maximum continuous reverse voltage before leakage exceeds 1.0 μA, ensuring no false triggering |
| VC @ IPPM | 21.2 V at 28.3 A (10/1000 μs) - clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 600 W - peak transient energy absorption capability without failure, validated per Fig. 1 curve |
| TJ max. | +175 °C - enables placement near hot engine-control units without thermal derating penalties |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance supports sustained surge handling with minimal PCB copper |
| AEC-Q101 | Qualified - certified for automotive electronic modules per stress test requirements (note: HE3 suffix denotes qualification; E3 is commercial grade) |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. No polarity marking - bidirectional symmetry eliminates cathode/anode orientation concerns.

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 | Same VBR (14.3–15.8 V), but SMC (DO-214AB) package - 50% smaller footprint, higher IPPM (38.9 A), lower RθJA (40 °C/W vs. 75 °C/W) | Better suited for space-constrained PCBs and higher ambient temperatures due to superior thermal performance | Select SMBJ15CA when board area is limited or junction temperature must stay below 150 °C under repeated surges |
| 1.5KE15CA | Same DO-15 package and VBR, but 1500 W PPPM rating - larger die, higher IPPM (100 A), higher VC (24.4 V), same VWM (12.8 V) | Targeted at higher-energy threats (e.g., ISO 16750-2 Pulse 4a) where 600 W is insufficient | Choose 1.5KE15CA when protecting against severe automotive load dump or lightning-induced surges exceeding 600 W capability |
Compared with P6KE15CA-E3/54, SMBJ15CA offers superior thermal efficiency and compactness for modern layouts, while 1.5KE15CA provides higher surge margin at the cost of increased clamping voltage and board space - enabling precise trade-offs between size, thermal headroom, and threat-level coverage.

FAQ
What does the "CA" suffix mean in P6KE15CA-E3/54?
The "CA" suffix indicates that P6KE15CA-E3/54 is a bidirectional Transient Voltage Suppressor. Unlike unidirectional versions (e.g., P6KE15A), it clamps voltage transients equally in both polarities - making it ideal for AC-coupled or differential signal lines where polarity reversal may occur. No cathode band marking is present on P6KE15CA-E3/54.
Is P6KE15CA-E3/54 AEC-Q101 qualified?
P6KE15CA-E3/54 carries the E3 suffix, which denotes RoHS-compliant commercial-grade construction. For AEC-Q101 qualification, Vishay specifies the HE3 suffix (e.g., P6KE15CAHE3/54). While P6KE15CA-E3/54 shares identical electrical specs and DO-15 packaging, only the HE3 variant has undergone full AEC-Q101 stress testing per the datasheet note on page 3.
What is the maximum clamping voltage of P6KE15CA-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE15CA-E3/54 is 21.2 V, measured at its rated peak pulse current of 28.3 A using the standardized 10/1000 μs waveform. This value represents the highest voltage the device allows across its terminals during worst-case transient events - a critical parameter for ensuring protected ICs remain within absolute maximum ratings.
How does P6KE15CA-E3/54 differ from unidirectional P6KE15A?
P6KE15CA-E3/54 is bidirectional with symmetrical VBR, VC, and leakage in both directions and no polarity marking. In contrast, P6KE15A is unidirectional, features a cathode band, conducts only in reverse bias, and has forward voltage drop (VF = 3.5 V at 50 A). Use P6KE15CA-E3/54 for AC signals or differential buses; use P6KE15A for DC power rail protection where polarity is fixed.
What is the thermal resistance of P6KE15CA-E3/54, and how does it affect layout?
P6KE15CA-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. To maintain reliability during repetitive surges, PCB layout should maximize copper area connected to both leads - ideally ≥100 mm² per lead - since heat is conducted primarily through the leads, not the epoxy body. Avoid narrow traces or thermal isolation.
