Product details
Overview
P6KE7.5AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in 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), 7.13–7.88 V breakdown voltage at 10 mA, 6.40 V stand-off voltage, 53.1 A peak pulse current, and clamps to ≤11.3 V under surge. Used in automotive ECUs and industrial sensor interfaces to prevent damage from inductive switching transients.
For engineers reviewing the P6KE7.5AHE3/54 datasheet, P6KE7.5AHE3/54 pinout, P6KE7.5AHE3/54 application, or P6KE7.5AHE3/54 equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), clamping behavior at rated IPPM, and DO-15 mechanical dimensions - all critical for board-level surge protection design and BOM validation.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt device: it remains high-impedance below 6.40 V (VWM) and avalanches sharply above 7.13 V (VBR min) to divert transient energy. Its glass-passivated junction enables fast response (<1 ns) and stable leakage (<500 μA at VWM).
Designed for single-pulse and low-duty-cycle repetitive surges (0.01 %), it sustains 100 A non-repetitive forward surge (8.3 ms half-sine) and exhibits +0.061 %/°C temperature coefficient on VBR, ensuring predictable clamping across -55 to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V at 10 mA - defines reliable avalanche initiation threshold for protection triggering |
| VWM | 6.40 V - maximum continuous working voltage before leakage exceeds 500 μA |
| VC @ IPPM | ≤11.3 V at 53.1 A - clamping voltage limiting downstream component stress during 600 W transient |
| IPPM | 53.1 A - peak surge current capability with 10/1000 μs waveform, defining protection margin |
| PPPM | 600 W - standardized surge power rating enabling direct comparison with IEC 61000-4-5 Level 4 requirements |
| TJ max | +175 °C - extended junction temperature rating supporting under-hood automotive placement |
| RθJL | 20 °C/W - thermal resistance from junction to lead, critical for PCB copper pour sizing in high-reliability designs |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; cathode indicated by color band on body end. Leads conform to J-STD-002 and JESD 22-B102 solderability standards; qualified per JESD 201 Class 2 whisker test (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-voltage rail; completes shunt path during avalanche conduction |
| Cathode (banded end) | High-side surge input terminal | Connected to protected line (e.g., 5 V rail); avalanche initiates when voltage exceeds VBR relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces |
| Glass passivated junction | Enables <1 ns response time and stable long-term leakage performance under thermal cycling |
| 600 W peak pulse power (10/1000 μs) | Meets IEC 61000-4-5 surge immunity requirements for industrial and automotive equipment |
| Low clamping ratio (VC/VBR ≈ 1.49) | Minimizes voltage overshoot on protected ICs during transient events, reducing risk of latch-up or gate oxide damage |
| UL 94 V-0 molding compound | Ensures flame-retardant enclosure integrity in safety-critical systems and enclosed enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | DO-214AA package; 7.0 V VWM, 7.78–8.61 V VBR, 600 W PPPM, RθJL = 15 °C/W | Surface-mount alternative with lower profile and improved thermal performance; requires SMT reflow process | Select SMBJ7.0A for space-constrained PCBs where automated assembly is preferred and thermal management via copper pour is limited |
| 1.5KE7.5A | DO-201AD package; identical VWM/VBR/PPPM; higher IFSM (200 A vs. 100 A); RθJL = 10 °C/W | Higher surge robustness for infrequent but extreme transients; larger axial footprint and higher weight | Choose 1.5KE7.5A when protecting high-energy circuits like motor drives where 200 A IFSM margin is required |
Compared with SMBJ7.0A and 1.5KE7.5A, P6KE7.5AHE3/54 offers AEC-Q101 qualification and JESD 201 Class 2 whisker resistance in a cost-optimized DO-15 through-hole package - making it optimal for automotive and industrial applications requiring proven reliability and manual or wave-solder compatibility.

FAQ
What is the clamping voltage of P6KE7.5AHE3/54 at its rated peak pulse current?
The P6KE7.5AHE3/54 clamps to a maximum of 11.3 V when subjected to its rated peak pulse current of 53.1 A (10/1000 μs waveform). This value is measured per standard test conditions in the Vishay datasheet (Document Number: 88369) and defines the upper voltage limit imposed on protected circuitry during surge events. The clamping voltage directly determines stress on downstream ICs and must be verified against their absolute maximum ratings. P6KE7.5AHE3/54 maintains this performance across its full operating temperature range.
Is P6KE7.5AHE3/54 qualified for automotive applications?
Yes, P6KE7.5AHE3/54 is AEC-Q101 qualified, as confirmed by the HE3 suffix and explicit note in the Vishay datasheet (Revision: 27-Sep-2021). This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and surge robustness required for automotive electronic control units. The device is rated for operation from -55 °C to +175 °C and meets JESD 201 Class 2 whisker resistance. P6KE7.5AHE3/54 is suitable for under-hood and cabin applications where reliability under harsh environmental conditions is mandatory.
What does the "HE3/54" suffix mean in P6KE7.5AHE3/54?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "54" denotes the preferred package code for 13-inch paper tape and reel packaging with 4000 units per reel. This ordering format aligns with Vishay's standard nomenclature where HE3 distinguishes automotive-grade versions from commercial E3 variants. P6KE7.5AHE3/54 is supplied in DO-15 (DO-204AC) package with matte tin-plated leads, and the full part number ensures traceability to qualified manufacturing lots and material specifications.
How does P6KE7.5AHE3/54 differ from unidirectional P6KE7.5A-E3/54?
P6KE7.5AHE3/54 and P6KE7.5A-E3/54 share identical electrical characteristics (VBR, VWM, VC, PPPM) and DO-15 package, but differ in qualification level: HE3 denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 is commercial grade with JESD 201 Class 1A. Both meet RoHS, but only P6KE7.5AHE3/54 is approved for automotive use. The thermal resistance (RθJL = 20 °C/W) and mechanical dimensions are identical. P6KE7.5AHE3/54 is the appropriate choice when automotive reliability standards are mandated.
Can P6KE7.5AHE3/54 be used in bidirectional configurations?
No, P6KE7.5AHE3/54 is strictly unidirectional, as indicated by the "A" suffix and absence of "CA" in the part number. Bidirectional variants (e.g., P6KE7.5CA) are explicitly designated and exhibit symmetrical clamping in both polarities. Using P6KE7.5AHE3/54 in reverse-biased configurations risks permanent failure due to lack of reverse avalanche capability. For AC line or differential signal protection requiring bidirectional clamping, select a CA-suffixed part or pair two unidirectional devices back-to-back. P6KE7.5AHE3/54 must be oriented with cathode toward the protected line and anode to ground.
