Product details
Overview
P6KE7.5A-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection at DC power rails and signal lines. It features a 7.13 V minimum breakdown voltage (VBR), 6.40 V maximum stand-off voltage (VWM), 11.3 V clamping voltage (VC) at 53.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and consumer power supply input stages.
For engineers reviewing the P6KE7.5A-E3/73 datasheet, P6KE7.5A-E3/73 pinout, P6KE7.5A-E3/73 application, or P6KE7.5A-E3/73 equivalent, this page delivers verified electrical parameters, DO-15 package mechanical data, clamping behavior under surge conditions, thermal derating curves, and AEC-Q101-qualified alternatives for automotive-grade design-in.
Technical Context
The P6KE7.5A-E3/73 operates as a silicon avalanche diode with glass-passivated junction, delivering bidirectional-capable surge suppression only when configured as a CA variant - this part is unidirectional, with cathode marked by color band. Its clamping response is defined at 10/1000 µs waveform, with 0.01 % duty cycle limit and thermal resistance RθJL = 20 °C/W.
It exhibits 500 µA maximum reverse leakage at VWM = 6.40 V, 3.5 V forward voltage at 50 A (per spec note), and temperature coefficient of 0.061 %/°C on VBR. Junction temperature range spans –55 °C to +175 °C, supporting under-hood and industrial ambient environments without derating below 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V at 10 mA test current - defines reliable avalanche initiation threshold across production lot |
| VWM | 6.40 V - maximum continuous reverse voltage before significant leakage; sets safe operating margin below VBR |
| VC @ IPPM | 11.3 V at 53.1 A - clamped voltage during 10/1000 µs transient; determines protected circuit's maximum stress level |
| PPPM | 600 W - peak surge power handling capacity; enables protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) |
| IFSM | 100 A - non-repetitive 8.3 ms half-sine surge current rating; validates robustness against inductive switch-off events |
| TJ max | +175 °C - maximum junction temperature; supports operation in high-ambient environments without forced cooling |
| RθJL | 20 °C/W - thermal resistance junction-to-lead; informs PCB copper pour requirements for sustained power dissipation |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. Cathode identified by color band; no marking on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); conducts during positive transients when cathode is biased higher |
| Cathode | Avalanche clamping terminal | Marked end; connected to protected line (e.g., 5 V rail); initiates breakdown when voltage exceeds VBR in reverse bias |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable VBR tolerance and long-term reliability under humidity and thermal cycling per JESD22-A101 |
| 600 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 surge immunity up to 4 kV open-circuit voltage in 2 Ω source impedance systems |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns rise time), critical for protecting CMOS inputs |
| Solder dip 275 °C max. for 10 s | Ensures lead integrity during wave soldering and reflow processes without delamination or parameter shift |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | DO-214AA package; 7.0 V VWM, 11.2 V VC @ 53.5 A; 600 W rating; same 10/1000 µs waveform | Surface-mount footprint; lower profile; requires PCB rework for through-hole replacement | Select SMBJ7.0A for space-constrained designs where automated SMT assembly is preferred and board layout allows DO-214AA placement. |
| P6KE7.5AHE3/73 | Identical electrical specs; AEC-Q101 qualified (HE3 suffix); same DO-15 package; RoHS-compliant | Qualified for automotive under-hood use per AEC-Q101; validated for 1000-cycle temperature cycling and HTRB | Choose P6KE7.5AHE3/73 when automotive qualification is mandatory - no change in circuit performance or layout required. |
Compared with SMBJ7.0A, P6KE7.5A-E3/73 offers through-hole mechanical stability for high-vibration environments; compared with P6KE7.5AHE3/73, it provides commercial-grade cost optimization where AEC-Q101 is not mandated - all three share identical VBR, VC, and PPPM performance.

FAQ
What is the breakdown voltage tolerance of P6KE7.5A-E3/73?
The P6KE7.5A-E3/73 has a specified breakdown voltage range of 7.13 V to 7.88 V at 10 mA test current, representing ±5.2 % tolerance about the nominal 7.5 V rating. This tolerance is guaranteed across operating temperature (–55 °C to +175 °C) and conforms to JEDEC standards for transient suppressors. The P6KE7.5A-E3/73 maintains this specification without binning or sorting.
Is P6KE7.5A-E3/73 suitable for bidirectional transient suppression?
No - P6KE7.5A-E3/73 is a unidirectional TVS diode, indicated by the "A" suffix. Bidirectional operation requires the "CA" suffix (e.g., P6KE7.5CA). The P6KE7.5A-E3/73 conducts only in reverse bias above VBR; forward conduction follows standard diode behavior with ~3.5 V VF at 50 A. For AC line or differential signal protection, P6KE7.5A-E3/73 must be paired with a second device or replaced with a CA variant.
What is the maximum clamping voltage of P6KE7.5A-E3/73 under surge conditions?
The maximum clamping voltage (VC) of P6KE7.5A-E3/73 is 11.3 V at 53.1 A peak pulse current, measured with a 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and represents the upper bound of voltage seen by downstream circuitry during worst-case surge events. The P6KE7.5A-E3/73 achieves this clamping with sub-nanosecond response and minimal overshoot due to its low dynamic impedance.
Does P6KE7.5A-E3/73 meet automotive qualification standards?
The P6KE7.5A-E3/73 is RoHS-compliant and meets commercial-grade specifications; it is not AEC-Q101 qualified. For automotive use, select the P6KE7.5AHE3/73 variant (HE3 suffix), which shares identical electrical parameters but includes full AEC-Q101 stress testing - including temperature cycling, HTRB, and ESD. The P6KE7.5A-E3/73 remains suitable for non-automotive industrial and consumer applications where qualification is not required.
How does thermal derating affect P6KE7.5A-E3/73 power handling above 25 °C?
P6KE7.5A-E3/73 power dissipation derates linearly above 25 °C ambient: at 75 °C lead temperature (TL), its rated power drops to 5.0 W (from 5.0 W at TL = 75 °C per Fig. 5), and full derating applies beyond that point. Peak pulse power (600 W) remains unchanged, but repetitive surge capability decreases with junction temperature rise. The P6KE7.5A-E3/73 uses RθJL = 20 °C/W to calculate allowable average power in continuous-duty scenarios.
