Product details
Overview
P6KE24HE3/73 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 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 power supply inputs and industrial sensor interfaces.
For engineers reviewing the P6KE24HE3/73 datasheet, P6KE24HE3/73 pinout, P6KE24HE3/73 application, or P6KE24HE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) package compatibility, 20.5 V stand-off voltage (VWM), and 1.0 µA max reverse leakage at VWM, critical for low-power battery-backed systems and ESD-sensitive analog front-ends.
Technical Context
This device operates as a voltage-clamping protector: under normal conditions it presents high impedance (>1 GΩ at VWM), but triggers into low-impedance conduction when transient voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown characteristics and fast response (<1 ns), enabling suppression of EFT bursts and inductive switching spikes before downstream ICs experience overstress.
The P6KE24HE3/73 is rated for 175 °C maximum junction temperature and exhibits a +0.094 %/°C temperature coefficient of VBR, supporting reliable operation across automotive under-hood thermal profiles. Its 20 °C/W junction-to-lead thermal resistance allows effective heat dissipation into PCB copper without heatsinking in pulsed-duty applications.
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 turn-on threshold for clamping transients above nominal 24 V rail |
| VWM | 20.5 V - maximum continuous reverse operating voltage; ensures no conduction during normal 24 V system operation |
| VC @ IPPM | 33.2 V at 18.1 A (10/1000 µs) - limits worst-case voltage seen by protected IC to safe margin below absolute maximum ratings |
| ID @ VWM | ≤1.0 µA - negligible standby current draw, essential for always-on battery-powered nodes |
| PPPM | 600 W - sustains single high-energy surges (e.g., ISO 7637-2 Pulse 1/2a/5a) without degradation |
| TJmax | 175 °C - supports placement near hot components (e.g., power MOSFETs, DC/DC converters) in automotive ECUs |
| Qualification | AEC-Q101 qualified - validated for automotive-grade reliability including HTOL, TC, and UHAST |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. Cathode indicated by color band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or lowest potential point; enables unidirectional clamping from cathode to anode |

Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance (±5 %) and long-term parameter stability under thermal cycling |
| 600 W peak pulse power (10/1000 µs) | Withstands automotive load dump surges (ISO 7637-2 Pulse 5a) without failure or parameter shift |
| AEC-Q101 qualification | Validated for automotive use including 1000-hour HTOL at 175 °C and 1000-cycle temperature cycling (-40 °C to +150 °C) |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage stress on protected devices - e.g., keeps 3.3 V MCU I/O within safe margin even during 18.1 A surge |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability for safety-critical assemblies |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|

Use Scenario: 24 V battery-fed ECU power input exposed to load dump (up to 60 V, 400 ms) and jump-start transients. IC Role / Device Role / Timing Role: Primary clamping element placed upstream of DC/DC converter input to limit voltage excursion before regulation stage. Use Value: Clamps peak voltage to ≤33.2 V at 18.1 A, preventing damage to 40 V-rated input capacitors and enabling use of cost-optimized 36 V input regulators. |
Use Scenario: Analog output line (e.g., 4–20 mA transmitter) routed through noisy factory environments with EFT coupling. IC Role / Device Role / Timing Role: Low-capacitance shunt protector on signal path, positioned adjacent to connector to intercept transients before op-amp input stage. Use Value: Sub-1 nS response captures fast EFT edges (IEC 61000-4-4), while 1.0 µA leakage avoids loading precision current loop accuracy. |
| Consumer Appliance Motor Drive Protection | Telecom DC Power Feeding Interface |
|
Use Scenario: Brushed DC motor driver board where back-EMF spikes exceed 50 V during commutation. IC Role / Device Role / Timing Role: Uni-directional TVS across H-bridge supply rail to clamp inductive kickback toward ground. Use Value: 600 W rating absorbs repetitive 10/1000 µs spikes without thermal runaway; DO-15 package fits tight layout constraints near motor terminals. |
Use Scenario: PoE-powered device (IEEE 802.3af/at) receiving 48 V DC over twisted pair, subject to lightning-induced surges. IC Role / Device Role / Timing Role: First-stage protector on PD (Powered Device) input, coordinated with gas discharge tube (GDT) for staged surge handling. Use Value: 20.5 V VWM allows full utilization of 48 V PoE range while clamping induced surges to <35 V, preserving IEEE-compliant isolation barriers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/5A | Same VBR range (22.8–25.2 V), but SMA package (surface-mount), lower PPPM = 400 W | Preferred for automated SMT assembly; unsuitable for high-energy load dump where 600 W is required | Select P6KE24HE3/73 for through-hole mounting and higher surge robustness; choose SMAJ24A-E3/5A only if board space and assembly method constrain package choice. |
| 1.5KE24A | Same DO-15 package and 600 W rating, but commercial-grade (non-AEC-Q101), higher VC = 36.0 V at same IPPM | Lacks automotive qualification; clamping voltage marginally higher, reducing protection margin for 3.3 V logic interfaces | Use P6KE24HE3/73 where AEC-Q101 compliance and tighter clamping are mandatory; 1.5KE24A acceptable only in non-automotive industrial settings with relaxed voltage margins. |
Compared with SMAJ24A-E3/5A and 1.5KE24A, the P6KE24HE3/73 uniquely combines AEC-Q101 qualification, 600 W surge capability, and DO-204AC through-hole packaging - making it the only option meeting automotive under-hood requirements while retaining legacy board assembly compatibility.

FAQ
What is the breakdown voltage tolerance for P6KE24HE3/73?
The P6KE24HE3/73 has a specified breakdown voltage range of 22.8 V to 25.2 V at 1.0 mA test current, representing a ±5 % tolerance around the nominal 24 V rating. This tight tolerance ensures predictable clamping behavior across production lots and temperature ranges, critical for protecting 24 V systems with narrow overvoltage margins. The P6KE24HE3/73 maintains this specification under AEC-Q101 stress conditions.
Is P6KE24HE3/73 suitable for bi-directional transient suppression?
No, the P6KE24HE3/73 is a uni-directional TVS diode, indicated by the "A" suffix and presence of cathode band marking. It conducts only when cathode voltage exceeds anode voltage by ≥VBR. For bi-directional protection, Vishay offers the P6KE24CA variant. Using P6KE24HE3/73 in AC or floating signal paths risks reverse breakdown failure; always verify polarity alignment in circuit design before deploying the P6KE24HE3/73.
What does the "HE3" suffix mean in P6KE24HE3/73?
The "HE3" suffix in P6KE24HE3/73 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this automotive-grade version from commercial "E3" variants (e.g., P6KE24A-E3/73), which lack AEC-Q101 validation. The "H" explicitly signals automotive qualification, while "E3" confirms lead-free matte tin plating and UL 94 V-0 molding compound - all verified per Vishay document 88369 for the P6KE24HE3/73.
How does P6KE24HE3/73 compare to P6KE24A-E3/73?
The P6KE24HE3/73 and P6KE24A-E3/73 share identical electrical parameters (VBR, VC, PPPM) and DO-204AC packaging, but differ in qualification: P6KE24HE3/73 is AEC-Q101 qualified and meets JESD 201 Class 2 whisker testing, whereas P6KE24A-E3/73 is commercial grade only. This makes the P6KE24HE3/73 mandatory for automotive applications and preferred in industrial systems requiring extended reliability validation. Both parts are pin-compatible and interchangeable only if qualification requirements align.
What is the maximum allowable lead temperature during soldering for P6KE24HE3/73?
The P6KE24HE3/73 supports solder dip at a maximum temperature of 275 °C for up to 10 seconds, per JESD 22-B106. This specification applies to wave soldering or manual tinning processes. Reflow profiles must comply with JEDEC J-STD-020 moisture sensitivity level (MSL) requirements - though as a non-MOS, non-plastic-packaged axial device, the P6KE24HE3/73 has no MSL rating and is not moisture-sensitive. Always confirm thermal profile against Vishay's recommended process for the P6KE24HE3/73.
