Product details
Overview
P6KE47HE3/73 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), 44.7–49.4 V breakdown voltage at 1 mA, 40.2 V stand-off voltage, 64.8 V maximum clamping voltage at 9.3 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE47HE3/73 datasheet, P6KE47HE3/73 pinout, P6KE47HE3/73 application, or P6KE47HE3/73 equivalent, this device serves as a robust, RoHS-compliant, lead-free transient protector for automotive ECUs, industrial sensor interfaces, and 24 V/48 V power supply inputs where fast response (<1 ns), low clamping ratio (1.61), and surge immunity to 100 A IFSM are required.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at 40.2 V), then avalanches sharply at VBR to limit transient energy by diverting surge current to ground. Its glass-passivated junction ensures stable breakdown and low leakage (<1 μA at VWM).
Thermal design relies on RθJL = 20 °C/W (junction-to-lead), enabling 5.0 W continuous dissipation at TL = 75 °C; derating begins above 25 °C ambient per Fig. 2. The device fails short-circuit under catastrophic overload, preserving downstream circuitry while tripping fuses or breakers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 44.7 V / 49.4 V at 1 mA - defines precise avalanche initiation window for repeatable clamping behavior |
| VWM | 40.2 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| VC @ IPPM | 64.8 V at 9.3 A (10/1000 μs) - actual worst-case voltage seen by protected IC during surge |
| PPPM | 600 W - peak transient energy absorption capability without degradation |
| IFSM | 100 A (8.3 ms half-sine) - surge current handling for inductive switch-off events |
| TJ max | +175 °C - enables operation in under-hood automotive environments and industrial enclosures |
| Qualification | AEC-Q101 qualified - validated for automotive electronics with temperature cycling, HTRB, and ESD testing |

IC Role / Device Role / Timing Role: Uni-directional TVS on 5 V or 12 V camera power line, mounted near connector to minimize inductance. Use Value: Achieves <1 ns response and sub-1 μA leakage at 5 V, preventing dark current drift and pixel noise in CMOS sensors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ45A-E3/57T | Lower PPPM (400 W), SMA package (surface-mount), VBR = 45–50 V, VC = 70.1 V @ 5.7 A | Better suited for space-constrained PCB layouts but requires rework for through-hole replacement | Select when board real estate is limited and thermal path supports lower power rating |
| 1.5KE47A | Same DO-15 package, 1500 W PPPM, higher IPPM (32.4 A), VC = 73 V @ 20.3 A, no AEC-Q101 | Higher surge margin for non-automotive industrial systems with less stringent qualification requirements | Choose for cost-sensitive 100–200 V surge environments where AEC-Q101 is not mandated |
Compared with SMAJ45A-E3/57T and 1.5KE47A, the P6KE47HE3/73 delivers optimal balance of AEC-Q101 compliance, 600 W surge capacity, and through-hole manufacturability-making it preferred for automotive Tier-1 production and industrial control modules requiring traceable, qualified components.

FAQ
What is the clamping voltage of the P6KE47HE3/73 under a standard 10/1000 μs surge?
The P6KE47HE3/73 has a maximum clamping voltage (VC) of 64.8 V at 9.3 A peak pulse current using the 10/1000 μs waveform. This value is measured per JEDEC standards and represents the highest voltage imposed on the protected circuit during full-rated surge conditions. It is confirmed in the Electrical Characteristics table on page 2 of Vishay document 88369.
Is the P6KE47HE3/73 suitable for automotive applications?
Yes, the P6KE47HE3/73 is AEC-Q101 qualified and explicitly rated for automotive use per Vishay's documentation. Its HE3 suffix denotes AEC-Q101 qualification, RoHS compliance, and JESD 201 Class 2 whisker resistance-making it appropriate for engine control units, ADAS cameras, and body electronics where reliability under thermal and mechanical stress is critical. The P6KE47HE3/73 meets all required stress tests including HTGB, TCT, and mechanical shock.
How does the P6KE47HE3/73 differ from the P6KE47A-E3/73?
The P6KE47HE3/73 differs from the P6KE47A-E3/73 solely in qualification grade: the "H" prefix indicates AEC-Q101 qualification, while the base "E3" version is commercial-grade only. Both share identical electrical parameters (VBR, VWM, VC, PPPM), DO-204AC package, and RoHS compliance. The P6KE47HE3/73 undergoes additional automotive-specific reliability testing, making it mandatory for Tier-1 automotive designs where P6KE47A-E3/73 would not be accepted.
What is the maximum operating temperature for the P6KE47HE3/73?
The P6KE47HE3/73 has a maximum junction temperature (TJ) of +175 °C and an operating junction/storage temperature range of –55 °C to +175 °C. This allows deployment in under-hood automotive environments and high-temperature industrial enclosures. Derating curves in Figure 2 of document 88369 define safe power limits above 25 °C ambient, with RθJL = 20 °C/W supporting thermal management via PCB copper pours or heatsinked leads.
Can the P6KE47HE3/73 be used in bi-directional configurations?
No, the P6KE47HE3/73 is a uni-directional TVS diode, as indicated by its "A" suffix and absence of "CA" designation. Bi-directional variants (e.g., P6KE47CA) are required for AC line or differential signal protection. Using the P6KE47HE3/73 in reverse-biased AC applications risks forward conduction and failure; its cathode-band marking confirms polarity-sensitive placement on DC rails only.
