Product details
Overview
P6KE9.1-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 9.1 V breakdown voltage (VBR = 8.65–9.55 V at IT = 1.0 mA), 13.4 V maximum clamping voltage (VC) at 44.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform. It is used to safeguard MOSFETs, ICs, and sensor interfaces against inductive switching transients in automotive and industrial control systems.
For engineers reviewing the P6KE9.1-E3/54 datasheet, P6KE9.1-E3/54 pinout, P6KE9.1-E3/54 application, or P6KE9.1-E3/54 equivalent, this device is evaluated for fast-response transient suppression in low-voltage (<12 V) DC circuits where stand-off voltage margin, clamping ratio, and AEC-Q101 qualification status are critical selection criteria.
Technical Context
This TVS operates as a silicon avalanche diode with glass-passivated junction, delivering sub-nanosecond response to ESD and surge events. Its unidirectional polarity enables integration into DC-biased lines without reverse conduction during normal operation, while its DO-204AC (DO-15) package supports through-hole mounting with 20 °C/W junction-to-lead thermal resistance.
Clamping performance is defined at IPPM = 44.8 A (10/1000 µs), yielding VC = 13.4 V - a 47% clamping ratio relative to VBR min. Temperature coefficient of VBR is +0.068 %/°C, ensuring predictable voltage drift across –55 °C to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 8.65 V / 9.55 V at 1.0 mA - defines precise avalanche initiation threshold for reliable turn-on before protected circuit damage |
| VWM | 7.78 V - maximum continuous reverse working voltage; ensures no leakage-induced stress on 9 V nominal rails |
| VC @ IPPM | 13.4 V at 44.8 A - clamps transients to safe level for 5–12 V logic and power ICs during 600 W surge events |
| IPPM | 44.8 A - peak surge current handling capacity under standardized 10/1000 µs waveform |
| PPPM | 600 W - peak pulse power rating; validates robustness against lightning-induced surges and inductive kickback |
| TJ max. | +175 °C - high junction temperature rating supports under-hood automotive and industrial environments |
| RθJL | 20 °C/W - low thermal resistance enables effective heat transfer to PCB copper or lead frame during repetitive pulses |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with matte tin-plated leads. Cathode identified by color band at one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0A | DO-214AA package; 9.0 V VBR; 13.1 V VC @ 43.5 A; 600 W rating | Surface-mount alternative with lower profile and higher board density; requires rework of footprint | Select SMBJ9.0A when space-constrained PCB layout or automated SMT assembly is required. |
| 1.5KE9.1A | Same DO-204AC package; identical VBR/VC specs; 1500 W PPPM rating | Higher-power variant for systems requiring margin beyond IEC 61000-4-5 Level 4; larger thermal mass | Choose 1.5KE9.1A if legacy design uses same footprint but demands higher surge endurance. |
Compared with SMBJ9.0A and 1.5KE9.1A, P6KE9.1-E3/54 offers optimal balance of cost, proven through-hole reliability, and AEC-Q101 qualification - making it preferred for automotive and industrial designs where manual assembly, thermal cycling resilience, and qualification traceability are prioritized over raw power headroom or miniaturization.

FAQ
What is the breakdown voltage tolerance of P6KE9.1-E3/54?
The P6KE9.1-E3/54 has a specified breakdown voltage range of 8.65 V to 9.55 V at test current IT = 1.0 mA, representing ±5% tolerance around the nominal 9.1 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports precise overvoltage margining in 9 V rail protection schemes. The P6KE9.1-E3/54 maintains this specification across its full operating temperature range.
Is P6KE9.1-E3/54 suitable for automotive applications?
Yes, P6KE9.1-E3/54 is AEC-Q101 qualified when ordered with the HE3 suffix (e.g., P6KE9.1HE3/54). The E3 suffix version is RoHS-compliant and rated for commercial use; however, the HE3 variant undergoes full AEC-Q101 stress testing including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing. For automotive body control or infotainment systems, specify P6KE9.1HE3/54 to ensure compliance. The P6KE9.1-E3/54 itself is not AEC-Q101 qualified.
What is the maximum clamping voltage of P6KE9.1-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE9.1-E3/54 is 13.4 V at peak pulse current IPPM = 44.8 A, measured using the standard 10/1000 µs double-exponential waveform. This value represents worst-case voltage seen by downstream circuitry during a 600 W transient event. The clamping ratio (VC/VBRmin) is approximately 1.55, confirming effective suppression for 12 V tolerant components. The P6KE9.1-E3/54 achieves this performance with minimal thermal drift due to its 20 °C/W RθJL.
How does P6KE9.1-E3/54 differ from P6KE9.1A?
P6KE9.1-E3/54 is a specific ordering variant of the P6KE9.1A base device, indicating RoHS-compliant construction (E3 suffix), tape-and-reel packaging (54 = 13" reel, 4000 pcs), and commercial-grade qualification. The "A" in P6KE9.1A denotes unidirectional polarity and standard electrical specs; the "-E3/54" adds packaging and compliance data. Electrically and functionally, P6KE9.1-E3/54 matches P6KE9.1A - both share identical VBR, VC, PPPM, and thermal characteristics. The P6KE9.1-E3/54 is the exact part number shipped and traceable by Aetrix Electronics.
Can P6KE9.1-E3/54 be used in bi-directional configurations?
No, P6KE9.1-E3/54 is strictly a unidirectional TVS diode, indicated by the absence of "C" in its part number (e.g., P6KE9.1CA would be bi-directional). Its cathode band marks the high-side connection point for DC-biased lines. Using it in AC or floating applications risks forward conduction during negative half-cycles, leading to overheating or failure. For bi-directional protection at 9.1 V standoff, select P6KE9.1CA - which has symmetric breakdown in both directions and no polarity marking. The P6KE9.1-E3/54 must be oriented correctly in-circuit to avoid unintended conduction.
