Product details
Overview
P6KE9.1AHE3/54 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 600 W peak pulse power (10/1000 μs), 7.78 V stand-off voltage (VWM), 8.65–9.55 V breakdown voltage (VBR at 1.0 mA), and clamps to ≤13.4 V at 44.8 A peak pulse current - deployed in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the P6KE9.1AHE3/54 datasheet, P6KE9.1AHE3/54 pinout, P6KE9.1AHE3/54 application, or P6KE9.1AHE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), junction temperature range (−55 to +175 °C), and DO-15 mechanical dimensions - all confirmed from Vishay's official document #88369 (Rev. 27-Sep-2021).
Technical Context
This unidirectional TVS operates as a voltage-clamping device triggered by transient overvoltages exceeding its VWM of 7.78 V. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping performance under repetitive 10/1000 μs pulses at 0.01 % duty cycle.
Designed for board-level protection, it sustains 100 A non-repetitive forward surge current (8.3 ms half-sine), exhibits 3.5 V max forward voltage at 50 A, and maintains operation across −55 °C to +175 °C junction temperature - with thermal derating defined per Fig. 2 and Fig. 5 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.78 V - maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown |
| VBR (min/max) | 8.65 V / 9.55 V at 1.0 mA - precise breakdown threshold ensures predictable turn-on during transients |
| VC @ IPPM | ≤13.4 V at 44.8 A - clamping voltage limits downstream IC stress during 600 W surge events |
| PPPM | 600 W - peak pulse power rating with 10/1000 μs waveform supports robust ESD and load-dump immunity |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance enables effective heat dissipation into PCB copper |
| TJ range | −55 °C to +175 °C - wide operating temperature span qualifies for under-hood automotive and industrial environments |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
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. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); conducts during positive transients when cathode is biased higher |
| Cathode | Clamping reference terminal | Marked end; connected to protected line (e.g., 12 V rail); initiates avalanche breakdown when voltage exceeds VBR |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0A | DO-214AA package; 9.0 V VWM, 10.0–11.1 V VBR, 14.4 V VC @ 41.7 A; 600 W rating | Surface-mount footprint; lower profile; higher thermal resistance (RθJA ≈ 40 °C/W vs. 75 °C/W for DO-15) | Select SMBJ9.0A for space-constrained PCBs where reflow assembly is preferred and thermal mass is sufficient. |
| 1.5KE9.1A | DO-201AD package; identical VWM/VBR/VC specs; same 600 W rating; non-AEC-Q101 commercial grade | Larger body size (3.6 mm diameter vs. DO-15's 2.2 mm); no automotive qualification; higher unit weight | Choose 1.5KE9.1A for cost-sensitive industrial designs where AEC-Q101 is not required and board space permits larger package. |
Compared with SMBJ9.0A and 1.5KE9.1A, P6KE9.1AHE3/54 uniquely combines AEC-Q101 qualification, DO-15 axial form factor for through-hole reliability, and 20 °C/W junction-to-lead thermal resistance - making it optimal for automotive and high-vibration industrial deployments requiring proven long-term stability.

FAQ
What is the clamping voltage of P6KE9.1AHE3/54 under maximum surge conditions?
The P6KE9.1AHE3/54 clamps to a maximum of 13.4 V when subjected to its rated peak pulse current of 44.8 A (10/1000 μs waveform). This value is measured per Figure 1 in Vishay document #88369 and represents the upper limit of voltage seen by protected circuitry during a 600 W transient event. The clamping behavior is repeatable and stable due to the device's glass-passivated junction and low incremental surge resistance.
Is P6KE9.1AHE3/54 suitable for automotive applications?
Yes, P6KE9.1AHE3/54 is AEC-Q101 qualified, as explicitly stated in the "Notes" section of Vishay document #88369 (Rev. 27-Sep-2021). The HE3 suffix denotes both RoHS compliance and AEC-Q101 qualification, covering tests including temperature cycling, high-temperature reverse bias, and ESD. It is deployed in automotive sensor units, body control modules, and infotainment power supplies.
What does the "HE3/54" suffix mean in P6KE9.1AHE3/54?
In P6KE9.1AHE3/54, "HE3" indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel delivery with 4000 units per reel. The base part P6KE9.1A defines the electrical characteristics, while HE3/54 confirms manufacturing and packaging compliance per Vishay's ordering information table on page 3 of document #88369.
How does P6KE9.1AHE3/54 differ from the standard P6KE9.1A-E3/54?
P6KE9.1AHE3/54 is AEC-Q101 qualified (HE3), whereas P6KE9.1A-E3/54 is commercial-grade only (E3). Both share identical electrical specs (VWM = 7.78 V, VBR = 8.65–9.55 V, VC = 13.4 V), DO-15 package, and RoHS compliance, but only the HE3 version undergoes automotive-grade stress testing per AEC-Q101. The E3 variant lacks qualification documentation and is intended for non-automotive industrial or consumer use.
What is the maximum operating temperature for P6KE9.1AHE3/54?
The P6KE9.1AHE3/54 has a maximum junction temperature (TJ) of +175 °C and a storage temperature range of −55 °C to +175 °C, as specified in the "Maximum Ratings" table of Vishay document #88369. Derating begins above 25 °C ambient, with power dissipation reduced linearly per the curve in Figure 5 - enabling reliable operation in under-hood automotive and high-temperature industrial enclosures.
