Product details
Overview
P6KE24-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 24 V breakdown voltage (VBR = 22.8–25.2 V at IT = 1.0 mA), 33.2 V maximum clamping voltage (VC) at 18.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive body electronics, industrial sensor interfaces, and consumer power supply inputs.
For engineers reviewing the P6KE24-E3/73 datasheet, P6KE24-E3/73 pinout, P6KE24-E3/73 application, or P6KE24-E3/73 equivalent, this device delivers verified AEC-Q101 qualification, DO-204AC (DO-15) package compatibility, glass-passivated junction reliability, and low incremental surge resistance - critical for ESD and load-dump transient suppression in space-constrained designs.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM = 20.5 V), then rapidly avalanches below 10 ns to limit transient energy. Its unidirectional polarity uses a cathode band marking and supports reverse-biased operation only - not symmetrical clamping like bi-directional variants (e.g., P6KE24CA).
Thermal performance is defined by RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), enabling 5.0 W steady-state dissipation at TL = 75 °C. The 175 °C max junction temperature and -55 °C to +175 °C operating range support under-hood and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V at 1.0 mA test current - defines precise avalanche onset threshold for repeatable clamping behavior |
| VWM | 20.5 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 33.2 V at 18.1 A (10/1000 μs) - ensures downstream ICs see no more than 33.2 V during worst-case surge |
| PPPM | 600 W - sustains single 10/1000 μs transients without degradation, suitable for ISO 7637-2 Pulse 1/2a/5a compliance |
| IFSM | 100 A (8.3 ms half-sine) - withstands repetitive inrush or fault currents without bond-wire fusing |
| TJ max | +175 °C - enables placement near heat-generating components in engine control units or motor drives |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 0.300" lead spacing, UL 94 V-0 molded epoxy |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical epoxy body with cathode band marking on one end. Matte tin-plated leads meet J-STD-002 solderability and JESD 201 Class 1A whisker resistance (E3 suffix). Lead length ≥1.0" (25.4 mm), diameter 0.028–0.034" (0.71–0.86 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND) in unidirectional configuration; conducts during forward surge |
| Cathode | Avalanche clamping terminal | Marked with color band; connected to protected line (e.g., 24 V rail); avalanches when VAK > VBR |
Key Features
| Feature | Design Value |
|---|---|

| AEC-Q101 qualified (HE3 variant); E3 meets commercial grade | P6KE24-E3/73 is RoHS-compliant commercial-grade; HE3 version adds automotive qualification for mission-critical nodes |
| Low clamping ratio (VC/VBR ≈ 1.35) | Minimizes overvoltage stress on protected MOSFET gates or MCU I/O pins during transient events |
| Fast response time < 10 ns | Clamps before sensitive logic or analog circuitry experiences destructive overvoltage |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | Same VBR (24 V), but SMC package (DO-214AB); 600 W rating; higher IPPM (32.4 A) | Surface-mount layout; better thermal dissipation via PCB copper; unsuitable for through-hole boards | Select SMBJ24A for automated assembly and improved thermal performance where board real estate permits SMC footprint. |
| P6KE24CA | Bi-directional variant; same VBR range but symmetric clamping (VC = 38.9 V); no polarity marking | Protects AC-coupled or bidirectional signal lines (e.g., RS-485, CAN); cannot replace unidirectional rail protection | Choose P6KE24CA only for balanced differential buses; P6KE24-E3/73 remains optimal for DC power rail clamping. |
Compared with SMBJ24A and P6KE24CA, P6KE24-E3/73 offers proven axial-leaded mechanical robustness, lower cost per unit in through-hole production, and tighter VBR tolerance - making it preferred for legacy automotive harness interfaces and industrial DIN-rail power supplies where manual assembly or vibration resistance is prioritized.

FAQ
What is the clamping voltage of P6KE24-E3/73 at its rated peak pulse current?
The P6KE24-E3/73 has a maximum clamping voltage (VC) of 33.2 V when subjected to its rated 18.1 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and guarantees that downstream circuitry will not experience voltages exceeding 33.2 V during such transient events. The P6KE24-E3/73 maintains this clamping performance across its full operating temperature range.
Is P6KE24-E3/73 suitable for automotive applications?
P6KE24-E3/73 is RoHS-compliant and manufactured to Vishay's commercial-grade specifications. While the HE3 variant (e.g., P6KE24HE3/73) is AEC-Q101 qualified for automotive use, the E3 suffix indicates commercial-grade qualification. Therefore, P6KE24-E3/73 may be used in non-safety-critical automotive subsystems (e.g., infotainment power rails) where full AEC-Q101 validation is not mandated - always verify system-level requirements before deployment. The P6KE24-E3/73 data sheet confirms its thermal and surge ratings align with many Tier-2 automotive environments.
How does the P6KE24-E3/73 differ from bi-directional TVS diodes like P6KE24CA?
The P6KE24-E3/73 is unidirectional and features a cathode band marking; it conducts only in reverse avalanche mode and blocks forward current above ~3.5 V. In contrast, P6KE24CA is bi-directional with symmetric clamping (VC = 38.9 V) and no polarity marking. The P6KE24-E3/73 is intended for DC rail protection where polarity is fixed, whereas P6KE24CA suits AC or differential signal lines. Using P6KE24-E3/73 in place of P6KE24CA on bidirectional paths risks forward conduction failure.
What is the maximum steady-state power dissipation for P6KE24-E3/73?
The P6KE24-E3/73 has a maximum steady-state power dissipation (PD) of 5.0 W when mounted on an infinite heatsink at a lead temperature (TL) of 75 °C. This rating assumes ideal thermal conduction from the leads and is derated linearly above 75 °C per the power derating curve in the datasheet. In typical PCB-mounted applications without heatsinking, practical continuous dissipation is limited to ~1.0–1.5 W due to higher thermal resistance. The P6KE24-E3/73 must not exceed its 175 °C maximum junction temperature under any operating condition.
Does P6KE24-E3/73 require a series current-limiting resistor in circuit design?
No, the P6KE24-E3/73 does not require a series current-limiting resistor for transient suppression - its clamping action is self-limiting based on avalanche characteristics. However, a series resistor is often used upstream to reduce peak current into the TVS during sustained overvoltage (e.g., short-circuit faults), preventing thermal runaway. For pure transient events (e.g., ESD, inductive spikes), the P6KE24-E3/73 operates effectively without external impedance, relying on its low dynamic impedance and fast response. Always validate total energy absorption against the P6KE24-E3/73's 600 W peak rating.
