Product details
Overview
5KP7.0A-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge clamping on DC power rails and signal lines. It features a 7.0 V stand-off voltage (VWM), 7.78–8.60 V breakdown voltage (VBR) at 50 mA, 5000 W peak pulse power (10/1000 µs), 417 A peak pulse current (IPPM), and clamps to ≤12.0 V at rated current - used in automotive power supply output protection and industrial sensor interface circuits.
For engineers reviewing the 5KP7.0A-E3/73 datasheet, 5KP7.0A-E3/73 pinout, 5KP7.0A-E3/73 application, or 5KP7.0A-E3/73 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, clamping performance under standardized transients, and RoHS-compliant packaging details - all critical for ESD/surge protection design validation and BOM selection.
Technical Context
The 5KP7.0A-E3/73 employs a glass-passivated P600 chip junction optimized for fast response (<1 ns) and low incremental surge resistance, enabling effective suppression of inductive switching spikes and lightning-induced surges. Its unidirectional polarity supports DC-biased rail protection with cathode-band marking, and it operates across –55 °C to +175 °C junction temperature range.
It is rated for 5000 W peak pulse power (10/1000 µs waveform, 0.01% duty cycle), dissipates 8.0 W continuously on infinite heatsink at TL = 75 °C, and withstands 600 A non-repetitive forward surge (8.3 ms half-sine). The device meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 1A whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - maximum continuous reverse operating voltage before clamping begins; sets upper limit for normal DC rail operation. |
| VBR min/max | 7.78 V / 8.60 V at 50 mA - guaranteed breakdown threshold ensures reliable turn-on during overvoltage events. |
| PPPM | 5000 W (10/1000 µs) - defines energy-handling capacity for transient suppression without failure. |
| VC @ IPPM | ≤12.0 V - clamping voltage under 417 A pulse; determines maximum stress imposed on downstream ICs. |
| ID @ VWM | ≤1000 µA - reverse leakage at stand-off voltage; low value minimizes standby power loss and false triggering. |
| TJ max | +175 °C - enables use in under-hood automotive and high-temperature industrial environments. |
| Polarity | Unidirectional - suitable for DC power line protection where reverse conduction is not required. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; UL 94 V-0 rated; cathode indicated by color band. Dimensions: 9.5 mm × 8.6 mm × 1.32 mm (L × W × H); lead spacing 9.1 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-potential node; completes clamping path during transient. |
| Cathode | High-side connection point | Marked by color band; connects to protected line (e.g., +12 V rail); conducts when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per JESD22 standards. |
| 5000 W peak pulse rating | Enables single-device protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 4 surges without cascaded stages. |
| Fast response time | Sub-nanosecond turn-on ensures clamping occurs before sensitive downstream components experience overstress. |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage margin between breakdown and clamping, improving system-level robustness. |
| RoHS-compliant & whisker-tested | E3 suffix meets JESD 201 Class 1A; supports lead-free reflow assembly and long-term interconnect reliability. |
Applications
| Automotive Power Supply Output Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Primary clamping element placed directly across input rail, shunting surge energy to ground before reaching DC-DC converter ICs. Use Value: Withstands 5000 W pulses and clamps to ≤12.0 V, preventing latch-up or damage to 15 V-rated regulators and microcontrollers. | Use Scenario: Safeguarding analog outputs of pressure/temperature sensors in factory automation PLC modules. IC Role / Device Role / Timing Role: Unidirectional TVS connected between signal line and ground, suppressing ESD and inductive kickback from solenoid drivers. Use Value: Low 1000 µA leakage at 7.0 V avoids loading 4–20 mA loop accuracy; fast response prevents sensor ADC saturation. |
| Telecom DC Feeder Protection | Computer Peripheral USB Power Rail Protection |
Use Scenario: Securing -48 V telecom rectifier outputs against lightning-induced surges on central office distribution lines. IC Role / Device Role / Timing Role: Cathode tied to -48 V rail, anode to ground; clamps negative-going transients while blocking steady-state reverse bias. Use Value: 175 °C max junction temperature supports operation in sealed, high-ambient telecom cabinets without forced cooling. | Use Scenario: Adding secondary surge immunity to USB Type-A VBUS lines in docking stations handling hot-plug events. IC Role / Device Role / Timing Role: Standoff voltage (7.0 V) matches USB 2.0/3.0 VBUS tolerance; clamps overshoots above 12 V during connector arcing. Use Value: 417 A peak pulse current rating handles multiple contact bounce events without degradation, extending product field life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | Lower PPPM (600 W), smaller SMB package, same VWM/VBR range. | Targeted at board-level signal line protection rather than bulk power rail clamping. | Select when space-constrained layouts require surface-mount devices and surge energy is ≤600 W. |
| 1.5KE7.0A | Same P600 package and 5000 W rating, but legacy DO-201 package variant; slightly higher VF (3.5 V vs. 3.2 V typical). | Legacy drop-in replacement with identical footprint and thermal profile; widely available in older designs. | Choose for backward compatibility in existing P600-based PCBs where E3 suffix compliance is not mandatory. |
Compared with SMBJ7.0A and 1.5KE7.0A, the 5KP7.0A-E3/73 offers superior energy handling in the same P600 form factor, AEC-Q101 qualification for automotive use, and tighter leakage control - making it optimal for new high-reliability power rail designs requiring certified surge immunity.

FAQ
What is the clamping voltage of the 5KP7.0A-E3/73 under maximum rated surge current?
The 5KP7.0A-E3/73 clamps to a maximum of 12.0 V when subjected to its rated peak pulse current of 417 A (10/1000 µs waveform). This clamping voltage is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 5KP7.0A-E3/73 suitable for automotive applications?
Yes, the 5KP7.0A-E3/73 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and infotainment power supplies. Its –55 °C to +175 °C operating junction temperature range, robust surge handling, and validated reliability testing meet stringent automotive environmental and lifetime requirements.
How does the 5KP7.0A-E3/73 differ from the 1.5KE7.0A in practical design use?
The 5KP7.0A-E3/73 and 1.5KE7.0A share identical P600 packaging and 5000 W peak pulse rating, but the 5KP7.0A-E3/73 carries the E3 suffix indicating RoHS compliance and JESD 201 Class 1A whisker resistance - essential for modern lead-free assembly. Both offer comparable electrical performance, but the 5KP7.0A-E3/73 is preferred for new designs requiring full regulatory alignment.
What is the maximum reverse leakage current of the 5KP7.0A-E3/73 at its stand-off voltage?
The 5KP7.0A-E3/73 exhibits a maximum reverse leakage current (ID) of 1000 µA at its 7.0 V stand-off voltage (VWM) and 25 °C ambient temperature. This low leakage ensures minimal impact on power rail efficiency and avoids false triggering in precision sensing or low-power standby circuits.
Can the 5KP7.0A-E3/73 be used in bidirectional protection configurations?
No - the 5KP7.0A-E3/73 is unidirectional only, with cathode marked by a color band. For bidirectional AC or dual-rail protection, a pair of 5KP7.0A-E3/73 devices in series opposition or a dedicated bidirectional TVS (e.g., 5KP7.0CA) must be used. Using a single unidirectional device in reverse-biased AC applications risks permanent breakdown.
