Product details
Overview
5KP15HE3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection on DC power rails and signal lines. It features 15 V standoff voltage (VWM), 16.7–18.5 V breakdown voltage (VBR) at 50 mA, 5000 W peak pulse power (10/1000 µs), clamping voltage of 24.4 V at 205 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the 5KP15HE3/73 datasheet, 5KP15HE3/73 pinout, 5KP15HE3/73 application, or 5KP15HE3/73 equivalent, this part is selected for robust overvoltage protection in switching power supply outputs, automotive ECUs, industrial motor drives, and sensor interface circuits where high IPPM, low clamping ratio, and thermal stability up to 175 °C are critical.
Technical Context
The 5KP15HE3/73 employs a glass-passivated P-N junction in a molded epoxy P600 case, optimized for fast response (<1 ns) and low incremental surge resistance to maintain tight clamping during multi-kilowatt transients. Its unidirectional polarity enables use in DC-biased rail protection without reverse conduction concerns.
Rated for 5000 W peak pulse power (10/1000 µs), it sustains 205 A peak pulse current with a maximum clamping voltage of 24.4 V - delivering a clamping ratio (VC/VWM) of 1.63 - and supports continuous power dissipation of 8.0 W on an infinite heatsink at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 15.0 V - Maximum continuous reverse voltage before significant leakage; sets operating margin below breakdown. |
| VBR (Breakdown Voltage) | 16.7–18.5 V at 50 mA - Confirmed avalanche initiation range; ensures predictable turn-on under surge. |
| VC (Clamping Voltage) | 24.4 V at IPPM = 205 A - Actual voltage seen by protected circuit during worst-case 5 kW transient. |
| PPPM (Peak Pulse Power) | 5000 W (10/1000 µs) - Sustains high-energy surges typical of load dump or inductive kick events. |
| IFSM (Surge Current) | 600 A (8.3 ms half-sine) - Withstands repetitive line-frequency overloads without degradation. |
| TJ max. | 175 °C - Enables operation in under-hood automotive and high-ambient industrial environments. |
| Polarity | Unidirectional - Requires correct orientation on DC rails; cathode marked by color band. |
Pinout & Package
Package: P600 - Axial-leaded, molded epoxy body (9.5 mm length × 6.2 mm diameter), UL 94 V-0 rated, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | DC input / low-side connection | Connected to ground or lower-potential node in unidirectional configuration; carries full surge return current. |
| Cathode | Protected line / high-side connection | Marked by color band; connected to rail being protected (e.g., +12 V battery line); avalanche conduction occurs here during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics per stress test requirements - supports ECU, ADAS, and body control module deployment. |
| 5000 W peak pulse rating (10/1000 µs) | Handles ISO 7637-2 Load Dump Pulse 5a (up to 110 V, 400 ms) with appropriate series impedance - eliminates need for crowbar circuits. |
| Clamping ratio VC/VWM = 1.63 | Minimizes overvoltage stress on downstream MOSFETs, regulators, and microcontrollers during transients. |
| Low incremental surge resistance | Ensures stable clamping performance across varying surge amplitudes - reduces voltage overshoot during fast-rising transients. |
| 175 °C max junction temperature | Enables reliable operation in sealed enclosures or near heat-generating components without derating penalties. |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive DC Bus |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump transients (ISO 7637-2 Pulse 5a) and jump-start spikes. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between battery rail and system input filter. Use Value: Clamps to 24.4 V at 205 A, limiting stress on upstream fuses and downstream DC/DC converters while maintaining AEC-Q101 compliance. |
Use Scenario: Safeguarding IGBT gate drivers and bus voltage monitors in variable-frequency drives exposed to inductive switching noise. IC Role / Device Role / Timing Role: Parallel-connected TVS on DC link capacitor terminals to absorb regenerative energy spikes. Use Value: 5000 W rating absorbs multi-cycle 10/1000 µs surges without degradation; 175 °C TJ rating supports operation near heatsinks. |
| Switching Power Supply Output | Sensor Interface Protection |
|
Use Scenario: Replacing crowbar SCR circuits on +5 V/+15 V outputs of industrial SMPS to reduce component count and improve reset behavior. IC Role / Device Role / Timing Role: Standoff-regulated TVS shunting overvoltage events before OVP latch triggers. Use Value: 15 V VWM aligns with nominal output; 24.4 V VC allows safe margin for downstream LDOs and logic ICs. |
Use Scenario: Shielding analog front-ends of current/voltage sensors in EV battery management systems from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance TVS (typ. <100 pF) placed at connector entry point before signal conditioning stage. Use Value: Fast sub-ns response prevents latch-up in precision amplifiers; unidirectional design avoids DC bias disruption on single-supply sensors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ15A | Lower PPPM (400 W), SMA package (surface-mount), 15 V VWM, 24.4 V VC at 12.3 A - not suitable for 5 kW surges. | Targeted at board-level ESD/surge on low-power signal lines, not primary power rail protection. | Select only for space-constrained PCBs with ≤500 W surge exposure; requires layout redesign and derating for automotive load dump. |
| ON Semiconductor 1.5KE15A | Same P600 package, 15 V VWM, but lower PPPM (1500 W), 24.4 V VC at 59.3 A - 70 % lower energy handling than 5KP15HE3/73. | Applicable for general-purpose industrial equipment with moderate surge immunity requirements (IEC 61000-4-5 Level 3). | Use where cost sensitivity outweighs peak energy demand; verify thermal margin under repeated 10/1000 µs pulses. |
Compared with SMAJ15A and 1.5KE15A, the 5KP15HE3/73 delivers 3.3× and 3.3× higher peak pulse power respectively, enabling direct protection of high-energy automotive and industrial power rails without external current-limiting resistors or staged clamping networks.

FAQ
What is the key difference between 5KP15HE3/73 and standard 1.5KE-series TVS diodes?
The 5KP15HE3/73 delivers 5000 W peak pulse power (10/1000 µs), more than three times the 1500 W rating of the 1.5KE15A. It also features AEC-Q101 qualification, 175 °C max junction temperature, and tighter clamping performance under high-current transients - making it suitable for automotive load dump and industrial motor drive protection where 1.5KE devices would fail catastrophically.
Is 5KP15HE3/73 compatible with lead-free reflow soldering processes?
No - the 5KP15HE3/73 is an axial-leaded through-hole device intended for wave soldering or hand soldering. Its matte tin-plated leads comply with J-STD-002 and support solder dip at 275 °C for up to 10 seconds. It is not rated for peak reflow temperatures exceeding 235 °C and lacks IPC/JEDEC moisture sensitivity level (MSL) classification.
Does 5KP15HE3/73 meet ISO 7637-2 Pulse 5a requirements for automotive load dump?
Yes - when used with appropriate series impedance (e.g., 1–5 Ω inline resistor or ferrite bead), the 5KP15HE3/73 clamps 110 V/400 ms load dump transients to ≤24.4 V, satisfying ISO 7637-2 Pulse 5a immunity requirements for 12 V systems. Its 5000 W rating and 205 A IPPM ensure survivability across multiple events.
What does the "HE3" suffix indicate in 5KP15HE3/73?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this automotive-grade variant from commercial "E3" versions (e.g., 5KP15A-E3/73), confirming enhanced reliability testing including temperature cycling, humidity bias, and mechanical shock per AEC-Q101 standards.
Can 5KP15HE3/73 be used in bidirectional configurations?
No - the 5KP15HE3/73 is unidirectional only, with cathode marked by a color band. For AC or bipolar signal line protection, a dedicated bidirectional TVS such as the 5KP15CA must be used. Attempting reverse-bias operation risks permanent junction damage due to lack of symmetrical avalanche structure.
