Product details
Overview
P6KE75CHE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 71.3 V minimum breakdown voltage (VBR), 64.1 V maximum stand-off voltage (VWM), 103 V clamping voltage (VC) at 5.8 A peak pulse current, 600 W peak pulse power rating (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability - deployed in engine control units, infotainment power supplies, and CAN bus interface protection.
For engineers reviewing the P6KE75CHE3/73 datasheet, P6KE75CHE3/73 pinout, P6KE75CHE3/73 application, or P6KE75CHE3/73 equivalent, key selection criteria include its DO-204AC (DO-15) package compatibility, uni-directional polarity with cathode band marking, 175 °C max junction temperature, and verified clamping performance under repetitive 10/1000 µs transients - critical for ESD and load-dump immunity in harsh-environment electronics.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM (64.1 V), it enters avalanche breakdown to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable VBR tolerance (±5% min/max spread: 71.3–78.8 V) and low incremental surge resistance, enabling consistent clamping at 103 V up to 5.8 A.
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), supporting operation from –55 °C to +175 °C. The device meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 2 whisker resistance (HE3 suffix), confirming suitability for reflow and automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64.1 V maximum - defines highest continuous DC or RMS voltage the device blocks without conduction; sets operating margin below breakdown. |
| VBR @ IT = 1 mA | 71.3–78.8 V - guaranteed avalanche initiation range; ensures predictable turn-on during transients above system rail. |
| VC @ IPPM = 5.8 A | 103 V - maximum clamped voltage seen by protected circuit during 10/1000 µs surge; determines residual stress on downstream ICs. |
| PPPM | 600 W - peak transient power dissipation capability; validates robustness against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surges. |
| IFSM | 100 A - non-repetitive forward surge rating (8.3 ms half-sine); supports protection during accidental reverse-bias faults or inductive kickback. |
| TJ max | +175 °C - enables placement near heat sources (e.g., power MOSFETs, motor drivers) without derating concerns in automotive modules. |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with 0.300" lead spacing; compatible with legacy through-hole assembly and automated insertion. |
Pinout & Package
Package: DO-204AC (DO-15), molded epoxy case with matte tin-plated leads. Cathode identified by color band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse surge return path | Connected to system ground or low-side reference; completes shunt path during transient events. |
| Cathode | Avalanche conduction terminal / High-voltage reference | Connected to protected line (e.g., 12 V battery rail); voltage sensed relative to anode to trigger clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR over temperature and lifetime; eliminates surface leakage paths that degrade clamping consistency. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive applications including powertrain, chassis, and ADAS modules per stress test requirements (HTOL, TC, HTRB). |
| 600 W peak pulse power (10/1000 µs) | Withstands ISO 7637-2 Load Dump (Pulse 5a) up to 35 V superimposed on 14 V nominal systems without degradation. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on protected ICs - e.g., keeps microcontroller I/O pins below absolute maximum ratings during surge events. |
| RoHS-compliant & halogen-free | Meets JEDEC JS709A and EU Directive 2011/65/EU; supports green manufacturing and end-of-life recycling compliance. |
Applications
| Automotive Power Rail Protection | CAN Bus Interface Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A | DO-214AA (SMB) package; 75 V VWM, 107 V VC @ 5.6 A; lower RθJA (50 °C/W) but higher mounting height. | Better thermal performance in SMT layouts; unsuitable for through-hole boards or space-constrained axial designs. | Select SMBJ75A only if PCB supports surface-mount assembly and thermal pad layout is available. |
| 1.5KE75A | DO-201AD package; identical VWM/VBR/VC specs but 1.5 kW PPPM; larger footprint and 1.1 g weight vs. 0.432 g for P6KE75CHE3/73. | Used where higher single-pulse energy absorption is required (e.g., telecom central office equipment), not automotive space/weight-sensitive modules. | Choose 1.5KE75A only when surge duty cycle demands >600 W capability and board real estate permits larger case. |
Compared with SMBJ75A and 1.5KE75A, P6KE75CHE3/73 delivers optimal balance of AEC-Q101 qualification, DO-15 mechanical compatibility, and 600 W surge handling in cost-sensitive automotive and industrial through-hole designs - avoiding SMT rework or oversized footprints.

FAQ
What is the polarity configuration of the P6KE75CHE3/73?
The P6KE75CHE3/73 is a uni-directional TVS diode, with the cathode clearly marked by a color band on the body. This polarity allows it to block up to 64.1 V in the forward direction while clamping reverse transients above 71.3 V. Its uni-directional nature makes it ideal for DC power rail protection where ground-referenced surges dominate - unlike bi-directional variants (e.g., P6KE75CA) used in AC-coupled or differential signal lines.
Does the P6KE75CHE3/73 meet automotive qualification standards?
Yes, the HE3 suffix in P6KE75CHE3/73 explicitly denotes AEC-Q101 qualification, verified per stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and highly accelerated temperature-humidity bias (HAST). This certification confirms suitability for under-hood and cabin electronics such as body control modules and infotainment power supplies - distinct from commercial-grade E3-only variants.
What is the maximum clamping voltage of the P6KE75CHE3/73 under surge conditions?
The P6KE75CHE3/73 clamps to a maximum of 103 V when subjected to a 10/1000 µs waveform with a peak current of 5.8 A. This value is measured per standard test conditions (TA = 25 °C) and represents the worst-case voltage imposed on protected circuitry during surge events - critical for ensuring downstream components like 100 V-rated MOSFETs or 80 V-input regulators remain within safe operating limits.
Can the P6KE75CHE3/73 be used in surface-mount designs?
No, the P6KE75CHE3/73 uses a DO-204AC (DO-15) axial-leaded package intended exclusively for through-hole mounting. Its 0.300" lead spacing and 1.0" minimum lead length are incompatible with SMT reflow profiles or pick-and-place tooling. For surface-mount alternatives, consider the SMBJ75A (DO-214AA) or SMCJ75A (DO-214AB), which share similar electrical specs but differ in thermal and mechanical implementation.
How does the P6KE75CHE3/73 handle repeated surge events?
The P6KE75CHE3/73 supports repetitive surge operation at a 0.01 % duty cycle (e.g., 4 pulses per minute), as defined in its peak pulse power rating. Its glass-passivated junction and 20 °C/W junction-to-lead thermal resistance enable self-cooling between pulses - validated for sustained use in automotive subsystems exposed to frequent load dumps or switching noise without parameter drift or parametric failure over 10,000+ cycles.
