Product details
Overview
P6KE15CAHE3/54 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 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, 600 W peak pulse power rating (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE15CAHE3/54 datasheet, P6KE15CAHE3/54 pinout, P6KE15CAHE3/54 application, or P6KE15CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, 175 °C max junction temperature, low leakage (<1.0 µA at VWM), and compliance with UL 497B surge protector classification.
Technical Context
This device operates as a voltage-clamped shunt protector: during transient overvoltage events exceeding VWM, it avalanches rapidly to limit voltage across protected circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance.
It delivers 600 W peak pulse power handling with 10/1000 µs waveform, supports repetitive surges at 0.01 % duty cycle, and maintains clamping performance across -55 °C to +175 °C operating junction temperature range. Thermal resistance is 20 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.3 V / 15.8 V - guaranteed avalanche initiation range at 1.0 mA test current; defines minimum overvoltage threshold before conduction |
| VWM | 12.8 V - maximum continuous reverse working voltage; circuit must operate below this to avoid leakage or premature conduction |
| VC @ IPPM | 21.2 V at 28.3 A - clamped voltage during 600 W transient; determines worst-case stress on downstream ICs or MOSFETs |
| IPPM | 28.3 A - peak pulse current supported under 10/1000 µs waveform; used to size upstream fusing or current-limiting impedance |
| PPPM | 600 W - transient energy absorption capacity; enables protection against common ESD, lightning-induced, and inductive-switching surges |
| TJ max | +175 °C - maximum junction temperature; allows operation in under-hood automotive or high-ambient industrial environments |
| Leakage @ VWM | <1.0 µA - minimal standby power loss and signal integrity impact in high-impedance sensor or communication lines |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case with matte tin-plated leads. RoHS-compliant, AEC-Q101 qualified (HE3 suffix), UL 94 V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side terminal in bidirectional configuration | No polarity marking; symmetric conduction in both directions - either lead may connect to line or ground |
| Cathode | High-side terminal in bidirectional configuration | Identical electrical behavior to anode; device functions identically regardless of orientation in PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines (e.g., RS-485, CAN, USB D+/D−) without polarity concerns |
| 600 W peak pulse power (10/1000 µs) | Withstands high-energy transients from inductive load switching or nearby lightning strikes without degradation |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and infotainment systems |
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure |
| UL 497B recognized (QVGQ2) | Meets safety requirements for telecom and industrial surge protection modules requiring third-party certification |
Applications
| Automotive Sensor Protection | Industrial RS-485 Interface |
|---|---|
|
Use Scenario: Protecting analog output lines of pressure or temperature sensors in engine bay environments subject to load dump and alternator ripple. IC Role / Device Role / Timing Role: Shunt clamping element placed between signal line and chassis ground to divert transients before reaching ADC input or signal conditioner. Use Value: Maintains signal integrity under 12 V system transients up to ±100 V; 21.2 V clamping prevents damage to 3.3 V or 5 V sensor interface ICs. |
Use Scenario: Safeguarding differential data lines in factory automation PLCs exposed to motor drive noise and relay coil kickback. IC Role / Device Role / Timing Role: Bidirectional TVS connected across A/B lines and to ground to suppress common-mode and differential-mode surges.

|
Use Scenario: Secondary-side transient suppression on 12 V DC output rails of wall adapters powering IoT hubs or set-top boxes. IC Role / Device Role / Timing Role: Low-leakage (≤1 µA) clamp limiting overvoltage from internal regulator fault or external backfeed. Use Value: Prevents latch-up or burnout of downstream DC-DC converters; 12.8 V VWM aligns with 12 V nominal rail with margin. |
Use Scenario: Primary protection stage on telephone line interface cards handling POTS or VoIP signals. IC Role / Device Role / Timing Role: UL 497B-recognized device placed before hybrid transformer to meet GR-1089-CORE surge immunity requirements. Use Value: Absorbs 600 W line-to-ground surges per ITU-T K.20/K.21; bidirectional symmetry matches AC-coupled telecom signaling. |
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/VC specs but SMC (DO-214AB) package; 600 W rating, lower RθJA (50 °C/W) | Better thermal performance in high-density layouts; requires surface-mount reflow, not through-hole | Select when board space is constrained and automated assembly is used; not drop-in compatible with DO-15 footprints |
| 1.5KE15CA | Same DO-15 package and VBR, but 1500 W peak power (10/1000 µs); higher IPPM (100 A) | Higher surge margin for severe industrial environments; larger junction capacitance (≈150 pF vs. ≈50 pF) | Choose when legacy DO-15 footprint must be retained but higher energy handling is required; verify signal-line capacitance limits |
Compared with SMBJ15CA and 1.5KE15CA, P6KE15CAHE3/54 offers optimal balance of AEC-Q101 qualification, UL recognition, compact DO-15 through-hole fit, and cost-effective 600 W protection - ideal for automotive and industrial designs where reliability, certification, and assembly flexibility are prioritized.

FAQ
What does the 'CA' suffix indicate in P6KE15CAHE3/54?
The 'CA' suffix denotes a bidirectional configuration: P6KE15CAHE3/54 conducts and clamps symmetrically in both polarities, making it suitable for AC-coupled or floating signal lines such as RS-485, CAN, or telecom interfaces. Unlike unidirectional variants (e.g., P6KE15A), it has no cathode marking and exhibits identical VBR and VC in either direction.
Is P6KE15CAHE3/54 suitable for automotive applications?
Yes - P6KE15CAHE3/54 carries the HE3 suffix, confirming AEC-Q101 qualification and JESD201 Class 2 whisker resistance. Its -55 °C to +175 °C operating range, glass-passivated junction, and UL 497B recognition make it appropriate for under-hood and body-control module deployments where transient immunity and long-term reliability are critical.
What is the maximum clamping voltage of P6KE15CAHE3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE15CAHE3/54 is 21.2 V, measured at its rated peak pulse current of 28.3 A using a 10/1000 µs waveform. This value represents the worst-case voltage imposed on protected circuitry during a full-rated transient event and is essential for ensuring downstream components remain within safe operating limits.
How does the DO-15 package of P6KE15CAHE3/54 affect thermal performance?
P6KE15CAHE3/54 in DO-15 (DO-204AC) package has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. Effective heat dissipation requires adequate copper pour on both leads and consideration of ambient temperature derating per Figure 2 in the datasheet; for sustained power dissipation, heatsinking via lead attachment is recommended.
Does P6KE15CAHE3/54 require orientation during PCB placement?
No - P6KE15CAHE3/54 is a bidirectional TVS diode with no polarity marking. Its symmetrical construction means either lead can be connected to the line or ground side of the protected circuit. This eliminates orientation errors during manual or automated assembly and simplifies layout for differential or AC-coupled signal paths.
