Product details
Overview
P6KE47AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 47 V breakdown voltage (VBR = 44.7–49.4 V at IT = 1.0 mA), 40.2 V standoff voltage (VWM), and clamps transients to ≤64.8 V at 9.3 A peak pulse current (10/1000 µs), delivering 600 W peak pulse power for automotive and industrial surge immunity.
For engineers reviewing the P6KE47AHE3/54 datasheet, P6KE47AHE3/54 pinout, P6KE47AHE3/54 application, or P6KE47AHE3/54 equivalent, this AEC-Q101 qualified device supports design-in for ESD and lightning-induced transient suppression in 12 V/24 V automotive subsystems, industrial PLC I/O modules, and telecom power interfaces where robust, low-leakage (<1.0 µA at VWM) unidirectional clamping is required.
Technical Context
This TVS operates as a silicon avalanche diode with glass-passivated junction, exhibiting fast response time (<1 ns) and low incremental surge resistance. Its unidirectional polarity-marked by cathode band-enables asymmetric clamping on positive-going transients while blocking reverse leakage below 1.0 µA at 40.2 V.
The device is rated for 175 °C maximum junction temperature and derates linearly above 25 °C ambient, with thermal resistance RθJL = 20 °C/W (junction-to-lead). It withstands 100 A non-repetitive forward surge (8.3 ms half-sine) and meets UL 94 V-0 flammability requirements in its molded epoxy DO-15 housing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 44.7 V / 49.4 V at 1.0 mA test current - defines precise avalanche onset window for reliable clamping threshold setting |
| VWM | 40.2 V - maximum continuous reverse operating voltage before significant leakage begins; sets safe DC rail margin |
| VC @ IPPM | ≤64.8 V at 9.3 A (10/1000 µs) - clamping voltage limiting downstream IC stress during surge events |
| IPPM | 9.3 A - peak surge current capacity enabling compliance with ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 3 |
| PPPM | 600 W - peak pulse power rating confirming suitability for high-energy transients in automotive and industrial environments |
| ID @ VWM | ≤1.0 µA - ultra-low reverse leakage ensuring minimal standby power loss in battery-powered systems |
| TJ max. | +175 °C - extended junction temperature rating supporting under-hood and high-ambient industrial deployment |
Pinout & Package
Package: DO-15 (DO-204AC), axial leaded, epoxy-molded, RoHS-compliant, AEC-Q101 qualified. Cathode indicated by color band on body.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ45A | DO-214AA package; 45 V VWM, 49.9 V VBR min, 70.1 V VC @ 8.6 A; 600 W rating | Surface-mount footprint; higher clamping voltage (+5.3 V) and lower IPPM (−0.7 A) than P6KE47AHE3/54 | Preferred for space-constrained PCBs where reflow assembly is used; requires layout revision due to SMD vs. axial leaded form factor |
| 1.5KE47A | DO-201AD package; identical VWM/VBR/VC specs but 1.5 kW peak power (10/1000 µs); larger body | Higher surge capacity for extreme environments (e.g., railway traction); 3× larger footprint and weight | Select when legacy 1.5 kW rating is mandated by system-level surge testing; not drop-in due to DO-201AD mechanical dimensions |
Compared with SMBJ45A and 1.5KE47A, P6KE47AHE3/54 offers optimal balance of AEC-Q101 qualification, DO-15 through-hole manufacturability, and precise 47 V clamping for cost-sensitive 12 V/24 V automotive and industrial designs-without requiring PCB redesign or over-spec'ed power handling.

FAQ
What is the standoff voltage (VWM) of P6KE47AHE3/54, and why does it matter?
The P6KE47AHE3/54 has a VWM of 40.2 V, meaning it remains in high-impedance state below this voltage-ensuring no interference with normal 36 V-rated circuit operation. This margin prevents false triggering while allowing full utilization of the 47 V breakdown window. Exceeding VWM risks increased leakage, so system DC rails must be held ≤40.2 V during steady-state operation for reliable P6KE47AHE3/54 performance.
Is P6KE47AHE3/54 suitable for automotive applications?
Yes, P6KE47AHE3/54 is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, infotainment power supplies, and body electronics. Its DO-15 package withstands vibration and thermal cycling, and its 600 W surge rating meets ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 5a (load dump) requirements-making P6KE47AHE3/54 a validated choice for under-hood and cabin systems.
How does the clamping voltage (VC) of P6KE47AHE3/54 compare to its breakdown voltage (VBR)?
P6KE47AHE3/54 clamps at ≤64.8 V when subjected to 9.3 A (10/1000 µs), yielding a clamping ratio (VC/VBR) of ~1.38-calculated using the nominal VBR midpoint (47.05 V). This tight ratio ensures minimal overvoltage overshoot during surge events, protecting downstream components like 60 V-rated MOSFETs and 5 V LDOs referenced to the same rail. The actual VC is measured per JEDEC standards and guaranteed across temperature.
What is the maximum junction temperature rating for P6KE47AHE3/54, and how does it affect thermal design?
P6KE47AHE3/54 is rated for TJ(max) = +175 °C, with thermal resistance RθJL = 20 °C/W (junction-to-lead). In practice, this allows operation at +125 °C ambient if lead temperature is maintained ≤75 °C (per Fig. 5 derating curve). Designers must ensure adequate copper pour and lead length (≥9.5 mm) to meet this; exceeding TJ risks parametric shift and reduced surge lifetime. P6KE47AHE3/54's rating enables use in high-ambient engine bay locations.
Does P6KE47AHE3/54 have bidirectional capability?
No, P6KE47AHE3/54 is strictly unidirectional, as indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P6KE47CA). Using P6KE47AHE3/54 on AC or bipolar signal lines would result in forward conduction during negative half-cycles, causing failure. For bidirectional protection, select P6KE47CA or verify polarity alignment before integrating P6KE47AHE3/54 into any circuit.
