Product details
Overview
P6KE33HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for overvoltage protection of sensitive electronics. It features a 31.4 V minimum breakdown voltage (VBR), 28.2 V maximum stand-off voltage (VWM), 45.7 V clamping voltage (VC) at 13.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive power line and industrial sensor interface protection.
For engineers reviewing the P6KE33HE3/54 datasheet, P6KE33HE3/54 pinout, P6KE33HE3/54 application, or P6KE33HE3/54 equivalent, this AEC-Q101 qualified TVS offers verified surge immunity for 12 V/24 V automotive subsystems, robust clamping performance under repetitive transients, and RoHS-compliant matte tin-plated leads suitable for J-STD-002 soldering.
Technical Context
The P6KE33HE3/54 operates as a uni-directional avalanche diode, triggered when reverse voltage exceeds its 31.4–34.7 V breakdown range at 1 mA test current. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low temperature coefficient (0.098 %/°C), enabling predictable clamping across -55 °C to +175 °C operating range.
It delivers 45.7 V clamping voltage at 13.1 A (10/1000 μs), with 1.0 μA max reverse leakage at 28.2 V stand-off, and supports 100 A non-repetitive forward surge (8.3 ms half-sine). Thermal resistance is 20 °C/W (junction-to-lead), supporting reliable power dissipation up to 5.0 W on infinite heatsink at 75 °C lead temperature.
Key Specifications

Use Scenario: Protecting 12 V battery-fed ECUs from load dump (ISO 7637-2 Pulse 5a, up to 60 V/100 ms) and alternator switching transients. IC Role / Device Role / Timing Role: Uni-directional TVS placed between battery rail and input filter capacitor to clamp overvoltage before DC-DC converter input stage. Use Value: Limits voltage to ≤45.7 V during 13.1 A surge, preventing damage to 40 V-rated input MOSFETs and LDOs in power management ICs. |
Use Scenario: Shielding 4–20 mA current loop transmitters from ESD and inductive kickback in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Mounted across loop terminals to shunt fast transients (<1 ns rise time) before reaching precision op-amps and ADC front-ends. Use Value: Clamps 8 kV contact ESD (IEC 61000-4-2) to <46 V within <1 ns, preserving 16-bit measurement accuracy and avoiding latch-up. |
| Consumer Power Adapter Input | Telecom Line Card Surge Protection |
|
Use Scenario: Safeguarding AC-DC adapter primary-side rectifiers and controllers against lightning-induced surges on mains input. IC Role / Device Role / Timing Role: Placed across bridge rectifier output to clamp differential-mode transients before bulk capacitor and PWM controller. Use Value: Absorbs 600 W peak energy while maintaining VWM = 28.2 V - compatible with 24 V nominal DC bus designs without false triggering. |
Use Scenario: Protecting Ethernet PHY and PoE PD controllers on telecom line cards from induced surges on RJ45 ports per GR-1089-CORE. IC Role / Device Role / Timing Role: Used in conjunction with common-mode chokes to suppress differential-mode surges on data pairs. Use Value: Achieves <1 ns response time and 45.7 V clamping, ensuring PHY ICs rated for 3.3 V I/O remain undamaged during 10/700 μs telecom surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33A | Same VWM (28.2 V) and VC (53.3 V), but lower PPPM (600 W same), smaller SMB package (DO-214AA) | Higher board density; lower thermal mass limits sustained surge duty cycle vs. DO-15 | Select SMBJ33A when space-constrained layouts require surface-mount footprint and thermal derating is acceptable |
| 1.5KE33A | Same VBR/VC specs, identical DO-201AD (DO-27) package, but commercial-grade only (no AEC-Q101) | Lacks automotive qualification; not approved for under-hood use or safety-critical modules | Choose 1.5KE33A for cost-sensitive consumer or industrial applications where AEC-Q101 is not mandated |
Compared with SMBJ33A and 1.5KE33A, the P6KE33HE3/54 uniquely combines AEC-Q101 qualification, DO-15 through-hole mechanical robustness, and proven thermal performance in high-temperature automotive environments - making it the preferred choice for production-grade vehicle electronics.

FAQ
What does the 'HE3/54' suffix mean in P6KE33HE3/54?
The 'HE3' suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; '/54' denotes 13-inch paper tape and reel packaging with 4000-unit quantity. This distinguishes P6KE33HE3/54 from commercial-grade variants like P6KE33A-E3/54, which lack automotive qualification.
Is P6KE33HE3/54 suitable for bi-directional transient protection?
No - P6KE33HE3/54 is strictly a uni-directional TVS diode, as confirmed by its part number ending in 'A' (not 'CA') and specification of forward voltage (VF = 3.5 V at 50 A). For bi-directional protection, Vishay specifies P6KE33CA variants, which have symmetrical breakdown in both polarities and no cathode marking.
How does the clamping voltage of P6KE33HE3/54 compare to its breakdown voltage?
The P6KE33HE3/54 has a minimum breakdown voltage (VBR) of 31.4 V and clamps to 45.7 V at 13.1 A peak pulse current, yielding a clamping ratio of ~1.46. This low ratio ensures minimal overvoltage stress on protected ICs - critical for safeguarding 36 V-rated automotive power management ICs during ISO 7637-2 transients.
Can P6KE33HE3/54 be used in place of P6KE33A in an existing design?
Yes - P6KE33HE3/54 is a drop-in replacement for P6KE33A in terms of electrical specs and DO-204AC package, but adds AEC-Q101 qualification and enhanced whisker resistance. No PCB changes are required; however, qualification documentation must be updated to reflect automotive-grade compliance for production release.
What is the maximum operating temperature for P6KE33HE3/54?
The P6KE33HE3/54 has a maximum junction temperature (TJ) of +175 °C and operates from -55 °C to +175 °C. This wide range supports deployment in engine control modules, transmission control units, and other under-hood automotive applications where ambient temperatures exceed 125 °C.
