Product details
Overview
P6KE9.1C-E3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for overvoltage protection on signal and power lines. It features a 9.1 V breakdown voltage (VBR min/max = 8.65–9.55 V at IT = 1.0 mA), 7.78 V stand-off voltage (VWM), 13.4 V clamping voltage (VC at IPPM = 44.8 A), and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the P6KE9.1C-E3/54 datasheet, P6KE9.1C-E3/54 pinout, P6KE9.1C-E3/54 application, or P6KE9.1C-E3/54 equivalent, this device serves as a RoHS-compliant, AEC-Q101-qualified transient protector requiring precise VWM/VBR margining, low clamping ratio (VC/VBR ≈ 1.40), and DO-15 package thermal management under repetitive surge conditions.
Technical Context
The P6KE9.1C-E3/54 operates as a bi-directional avalanche diode, symmetrically clamping voltage transients in both polarities without polarity marking. Its glass-passivated junction enables sub-nanosecond response to ESD and lightning-induced surges, while its 20 °C/W junction-to-lead thermal resistance supports sustained 5.0 W power dissipation at TL = 75 °C.
It complies with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge) immunity requirements when applied with proper PCB layout - including minimized trace inductance and direct grounding to protect downstream MOSFETs, op-amps, or microcontroller I/O pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 8.65 V / 9.55 V at IT = 1.0 mA - defines reliable avalanche initiation threshold across temperature and unit variation |
| VWM | 7.78 V - maximum continuous reverse working voltage before leakage exceeds 50 μA |
| VC @ IPPM | 13.4 V at 44.8 A (10/1000 μs) - limits protected circuit voltage during worst-case surge |
| PPPM | 600 W - peak transient energy absorption capability per single pulse |
| IPPM | 44.8 A - maximum non-repetitive surge current the device safely clamps |
| TJ max | 175 °C - enables operation in under-hood automotive and high-ambient industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0CA | DO-214AA package; 9.0 V VBR; 12.6 V VC @ 48.6 A; lower RθJA (50 °C/W vs. 75 °C/W) | Surface-mount alternative with higher surge current rating but reduced thermal mass for short-duration pulses | Select SMBJ9.0CA for space-constrained PCBs where reflow compatibility and automated assembly are required |
| 1.5KE9.1C | Same DO-15 package; 9.1 V VBR; 13.4 V VC @ 44.8 A; identical electrical specs but commercial-grade (non-AEC-Q101) | Cost-optimized replacement where automotive qualification is not mandated | Choose 1.5KE9.1C for consumer or industrial applications lacking automotive reliability requirements |
Compared with SMBJ9.0CA and 1.5KE9.1C, the P6KE9.1C-E3/54 uniquely combines AEC-Q101 qualification, axial-leaded DO-15 form factor, and verified 175 °C junction operation - making it the preferred choice for under-hood automotive designs requiring through-hole robustness and extended temperature compliance.

FAQ
What is the key difference between P6KE9.1C-E3/54 and uni-directional P6KE9.1A-E3/54?
The P6KE9.1C-E3/54 is bi-directional with symmetrical clamping in both polarities and no cathode band marking, whereas the P6KE9.1A-E3/54 is uni-directional with a cathode band and conducts only in reverse bias. The C-suffix version supports AC-coupled or floating signal lines like RS-485 or audio paths, while the A-suffix suits DC-biased rails such as 5 V supply lines. Both share identical VBR, VC, and PPPM ratings.
Does P6KE9.1C-E3/54 meet AEC-Q101 requirements?
Yes, P6KE9.1C-E3/54 is AEC-Q101 qualified per the Vishay datasheet revision 18-Sep-12 (Document Number: 88369). This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD - confirming suitability for automotive electronic control units, body modules, and ADAS sensor interfaces where reliability under thermal and mechanical stress is mandatory.
What is the maximum clamping voltage of P6KE9.1C-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE9.1C-E3/54 is 13.4 V at a peak pulse current (IPPM) of 44.8 A with a 10/1000 μs waveform. This value is measured at TA = 25 °C and represents the upper limit of voltage imposed on protected circuitry during worst-case transient events - critical for ensuring compatibility with 3.3 V or 5 V logic interfaces.
Can P6KE9.1C-E3/54 be used in place of P6KE9.1A-E3/54 without circuit modification?
No - P6KE9.1C-E3/54 cannot be directly substituted for P6KE9.1A-E3/54 without verifying circuit topology. The bi-directional P6KE9.1C-E3/54 clamps in both directions and lacks polarity marking, while the uni-directional P6KE9.1A-E3/54 requires correct anode/cathode orientation. Replacing one with the other on a DC-biased rail may cause unintended conduction or failed protection; redesign is needed for polarity-sensitive placements.
What is the thermal resistance specification for P6KE9.1C-E3/54?
P6KE9.1C-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient resistance (RθJA) of 75 °C/W at TA = 25 °C. These values govern power derating: at lead temperature (TL) = 75 °C, the device sustains 5.0 W continuous dissipation; above that, linear derating applies per Figure 5 in the Vishay datasheet.
