Product details
Overview
P6KE9.1CHE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of sensitive electronics. It features a 9.1 V breakdown voltage (VBR = 8.65–9.55 V at IT = 1.0 mA), 7.78 V stand-off voltage (VWM), 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 - used to safeguard MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in automotive and industrial systems.
For engineers reviewing the P6KE9.1CHE3/54 datasheet, P6KE9.1CHE3/54 pinout, P6KE9.1CHE3/54 application, or P6KE9.1CHE3/54 equivalent, this device is selected for cost-sensitive, high-surge-capability DC rail protection where fast response (<1 ns), low clamping ratio (VC/VBR ≈ 1.4), and AEC-Q101 qualification are required - especially in 12 V automotive subsystems, power supply input stages, and industrial I/O interfaces.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), but avalanches rapidly when reverse voltage exceeds VBR, diverting surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (≤50 μA at VWM).
It is rated for 100 A non-repetitive forward surge current (IFSM), supports continuous power dissipation of 5.0 W on infinite heatsink, and maintains operation across –55 °C to +175 °C junction temperature range - enabled by low thermal resistance (RθJL = 20 °C/W) and UL 94 V-0 compliant epoxy encapsulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 8.65 V / 9.55 V at IT = 1.0 mA - defines precise avalanche onset threshold for reliable triggering |
| VWM | 7.78 V - maximum continuous reverse working voltage before leakage rises significantly |
| VC @ IPPM | 13.4 V at 44.8 A - clamping voltage limiting stress on protected ICs during 10/1000 μs surge |
| PPPM | 600 W - peak transient energy handling capacity per single 10/1000 μs pulse |
| IPPM | 44.8 A - maximum surge current the device safely clamps without degradation |
| TJ max. | +175 °C - enables use in under-hood automotive environments and high-ambient industrial enclosures |

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 (min 8.55 V); 14.5 V VC @ 41.4 A; same 600 W rating | Surface-mount alternative with higher thermal resistance (RθJA ≈ 40 °C/W vs. 75 °C/W for DO-15), better suited for PCB space-constrained designs | Select SMBJ9.0A when automated SMT assembly is required and board layout allows for thermal pad design. |
| 1.5KE9.1A | Same DO-204AC package; identical VBR and VC; 1500 W peak power (10/1000 μs), higher IPPM (116 A) | Higher surge capacity suits applications exposed to repeated or severe transients (e.g., generator-fed industrial equipment) | Choose 1.5KE9.1A where legacy 1.5 kW surge margin is mandated, accepting larger footprint and higher cost. |
Compared with SMBJ9.0A and 1.5KE9.1A, P6KE9.1CHE3/54 offers optimal balance of AEC-Q101 qualification, axial-leaded through-hole manufacturability, and 600 W surge capability - making it preferred for cost-sensitive, high-volume automotive and industrial control boards requiring proven reliability and easy hand-soldering or wave soldering.

FAQ
What is the breakdown voltage tolerance for P6KE9.1CHE3/54?
The P6KE9.1CHE3/54 has a specified breakdown voltage range of 8.65 V to 9.55 V at test current IT = 1.0 mA, corresponding to ±5% tolerance around the nominal 9.1 V rating. This tight VBR window ensures consistent triggering behavior across production lots and supports predictable system-level surge margin calculations in designs using P6KE9.1CHE3/54.
Is P6KE9.1CHE3/54 suitable for automotive applications?
Yes, P6KE9.1CHE3/54 is AEC-Q101 qualified (denoted by HE3 suffix), meaning it has passed stress tests including high-temperature operating life, temperature cycling, and humidity bias HAST - validating its suitability for under-hood and cabin automotive electronics. Its 175 °C max junction temperature and robust clamping performance make P6KE9.1CHE3/54 appropriate for 12 V rail protection in ECUs, lighting modules, and body control units.
What does the "HE3/54" suffix mean in P6KE9.1CHE3/54?
In P6KE9.1CHE3/54, "HE3" indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 class 2 whisker resistance; "/54" specifies the packaging format: 13-inch paper tape and reel, 4000 units per reel. This ordering code ensures traceable, automotive-grade material with standardized logistics - critical for production planning and quality control when procuring P6KE9.1CHE3/54.
How does P6KE9.1CHE3/54 compare to bi-directional TVS diodes like P6KE9.1CHE3/54CA?
P6KE9.1CHE3/54 is uni-directional (cathode-banded), intended for DC line-to-ground protection, whereas P6KE9.1CHE3/54CA is bi-directional and used for AC or data-line protection where polarity reversal occurs. The CA variant has symmetric breakdown in both directions and no polarity marking. For 12 V automotive supply rails, P6KE9.1CHE3/54 provides lower leakage and tighter VBR control than its CA counterpart - key advantages when selecting P6KE9.1CHE3/54 for unidirectional DC systems.
What is the maximum clamping voltage of P6KE9.1CHE3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE9.1CHE3/54 is 13.4 V, measured at peak pulse current IPPM = 44.8 A with a 10/1000 μs waveform. This value represents the worst-case voltage seen by protected circuitry during a full-rated surge event - enabling designers to verify that downstream components (e.g., microcontrollers rated for 16 V absolute maximum) remain within safe operating limits when P6KE9.1CHE3/54 is deployed.
