Product details
Overview
P6KE75CHE3/54 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 DC power rails and signal lines. It features 600 W peak pulse power (10/1000 μs), 71.3–78.8 V breakdown voltage at 1 mA, 64.1 V stand-off voltage, 103 V maximum clamping voltage at 5.8 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE75CHE3/54 datasheet, P6KE75CHE3/54 pinout, P6KE75CHE3/54 application, or P6KE75CHE3/54 equivalent, key selection criteria include clamping voltage margin vs. protected IC's absolute maximum rating, thermal derating above 25 °C, lead temperature limits during reflow/soldering, and compliance with IEC 61000-4-2/4-4/4-5 surge immunity requirements.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at 64.1 V), but avalanches rapidly (<1 ns response) when transient voltage exceeds VBR, diverting surge current away from downstream components. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 μA at VWM).
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient); power dissipation is limited to 5.0 W on infinite heatsink at TL = 75 °C, with full derating above 25 °C ambient per Fig. 2. The device fails short-circuit under catastrophic overload, enabling fuse/breaker coordination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 600 W - sustains single transient surges up to this energy level without degradation |
| Stand-off Voltage VWM | 64.1 V - maximum continuous DC or RMS voltage applied without significant leakage |
| Breakdown Voltage VBR | 71.3–78.8 V at 1 mA - precise avalanche onset threshold defining protection trigger point |

Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: 12 V battery rail in engine control unit exposed to load dump (ISO 16750-2) and alternator ripple. IC Role / Device Role / Timing Role: Shunt clamping element placed between VBAT and GND, triggered within nanoseconds of overvoltage onset. Use Value: Limits voltage to ≤103 V during 35 V/100 ms load dump, protecting 36 V-rated DC-DC converters and microcontrollers. |
Use Scenario: Analog output line (4–20 mA) of pressure sensor in factory automation PLC I/O module. IC Role / Device Role / Timing Role: Bidirectional protection not applicable; P6KE75CHE3/54 used unidirectionally on supply side to suppress ESD and inductive kickback. Use Value: Clamps 8 kV contact ESD (IEC 61000-4-2) to <103 V, preventing latch-up in op-amp input stages and ADC front-end. |
| Telecom Line Card Surge Protection | Consumer Power Adapter Input Stage |
|
Use Scenario: Primary-side DC bus (48 V) in PoE-powered network switch line card subjected to lightning-induced surges. IC Role / Device Role / Timing Role: First-stage clamping device upstream of DC-DC controller, coordinated with MOV and fuse. Use Value: Absorbs 600 W transient energy while maintaining clamping below 103 V, preserving 60 V-rated MOSFETs and gate drivers. |
Use Scenario: Output rail of 24 V wall adapter powering smart home hub, subject to user-induced plug/unplug transients. IC Role / Device Role / Timing Role: Final-stage overvoltage clamp after bulk capacitor, guarding USB-C PD controller and PMIC inputs. Use Value: Prevents >64.1 V sustained overvoltage from damaging 5.5 V tolerant logic, with <1 μA leakage preserving no-load efficiency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A | Same VBR range (71.3–78.8 V), but SMC (DO-214AB) package; 600 W rating, lower RθJA (50 °C/W) | Better thermal performance in surface-mount layouts; requires PCB rework for leaded replacement | Select SMBJ75A for new SMT designs requiring higher power density and automated assembly. |
| 1.5KE75A | Same DO-204AC package and VBR, but 1500 W peak power (10/1000 μs); larger die, higher IPPM (19.5 A) | Higher surge margin for infrequent but extreme events (e.g., direct lightning coupling) | Choose 1.5KE75A where system-level testing demands >600 W headroom and board space allows larger body. |
Compared with SMBJ75A and 1.5KE75A, P6KE75CHE3/54 offers optimal balance of AEC-Q101 qualification, proven reliability in through-hole automotive harnesses, and cost-effective 600 W protection-making it preferred for legacy and hybrid assembly environments where DO-15 footprint and leaded mounting are mandated.

FAQ
What is the clamping voltage of P6KE75CHE3/54 at its rated peak pulse current?
The P6KE75CHE3/54 has a maximum clamping voltage (VC) of 103 V at 5.8 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value defines the upper voltage limit imposed on the protected circuit during a worst-case surge event and must be verified against the absolute maximum ratings of downstream components. The P6KE75CHE3/54 maintains this clamping performance across its qualified operating temperature range.
Is P6KE75CHE3/54 suitable for bi-directional transient protection?
No, P6KE75CHE3/54 is a uni-directional TVS diode, indicated by the "A" suffix and cathode band marking. It conducts only when reverse-biased beyond VBR. For bi-directional protection (e.g., AC lines or data pairs), Vishay specifies CA-suffix variants like P6KE75CA. Using P6KE75CHE3/54 in bi-directional configurations risks forward conduction and failure during positive half-cycles.
Does P6KE75CHE3/54 meet automotive qualification standards?
Yes, P6KE75CHE3/54 carries the HE3 suffix, confirming AEC-Q101 qualification per the Vishay datasheet revision 18-Sep-12. This includes stress testing for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life-validating suitability for automotive powertrain, body control, and infotainment systems where reliability under harsh conditions is mandatory.
What is the maximum continuous DC voltage that can be applied to P6KE75CHE3/54?
The maximum steady-state DC voltage (stand-off voltage VWM) for P6KE75CHE3/54 is 64.1 V. Operating above this level increases reverse leakage current exponentially and risks thermal runaway. Designers must ensure system nominal voltage plus tolerance (e.g., 12 V ±15 % = 13.8 V) remains well below 64.1 V, with margin for ripple and transients before clamping initiates.
How does the thermal resistance of P6KE75CHE3/54 affect its power handling?
P6KE75CHE3/54 has RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient). At 25 °C ambient, its 5.0 W power dissipation limit drops linearly above 25 °C per the derating curve in Fig. 5. Effective heat sinking via PCB copper pour or lead length optimization is essential to maintain junction temperature ≤175 °C during repetitive surges or elevated ambient conditions.
