Product details
Overview
5KP10-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 power rails and signal lines. It features 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 5.0 mA, 17.0 V maximum clamping voltage (VC) at 294 A peak pulse current (IPPM), and 5000 W peak pulse power (10/1000 μs waveform).
For engineers reviewing the 5KP10-E3/73 datasheet, 5KP10-E3/73 pinout, 5KP10-E3/73 application, or 5KP10-E3/73 equivalent, this device is selected for robust overvoltage protection in automotive power supplies, industrial motor drives, and telecom DC-DC output stages where fast response (<1 ns), low clamping ratio, and AEC-Q101 qualification are required.
Technical Context
The 5KP10-E3/73 uses a glass-passivated P600 junction to achieve stable avalanche behavior under repetitive 10/1000 μs transients at 0.01% duty cycle. Its unidirectional polarity enables integration into DC-biased circuits without reverse conduction concerns during normal operation.
Clamping performance is defined by low incremental surge resistance and fast response time-critical for protecting MOSFETs and ICs from inductive switching spikes and lightning-induced surges. The device operates across –55 °C to +175 °C junction temperature and meets JESD 22-B106 soldering requirements (275 °C, 10 s).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10.0 V - Maximum continuous reverse voltage before clamping begins; sets operating margin above nominal 9–10 V rail. |
| VBR (min/max) | 11.1 V / 12.3 V at 5.0 mA - Tight 10% tolerance ensures predictable turn-on threshold across production lots. |
| VC @ IPPM | 17.0 V at 294 A - Clamps 10/1000 μs surge to safe level for downstream 20 V-rated components. |
| PPPM | 5000 W - Sustains single high-energy transients common in automotive load-dump (ISO 7637-2) and industrial switching events. |
| IFSM | 600 A (8.3 ms half-sine) - Withstands short-circuit fault currents long enough for upstream fuses to clear. |
| TJ max. | +175 °C - Enables use in under-hood automotive environments and high-temperature industrial enclosures. |
| Polarity | Unidirectional - Cathode-band marked; blocks reverse leakage below VWM, conducts only during positive overvoltage events. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; UL 94 V-0 rated; RoHS-compliant (E3 suffix); cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; defines clamping path for positive transients. |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., +12 V rail); avalanche conduction occurs when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and chassis applications per stress test requirements (HTOL, TC, HAST, etc.). |
| 5000 W peak pulse rating (10/1000 μs) | Handles ISO 7637-2 Pulse 5a (load dump) up to 120 V without failure or parameter shift. |
| Clamping ratio VC/VBR = 1.53 | Delivers superior voltage limiting vs. standard TVS diodes (typical ratio >1.6), reducing stress on protected ICs. |
| Low IR ≤ 20 μA at VWM | Minimizes standby power loss in battery-backed systems and avoids false triggering in high-impedance sensor interfaces. |
| Solderable per J-STD-002/JESD 22-B102 | Ensures reliable lead termination in wave and reflow processes without dewetting or voiding. |
Applications
| Automotive Power Supply Protection | Industrial Motor Drive DC Bus |
|---|---|
Use Scenario: Protecting 12 V vehicle electronics against load-dump transients (up to 120 V, 400 ms) and jump-start surges. IC Role / Device Role / Timing Role: Primary clamping element on main battery feed; activates within <1 ns to limit voltage seen by MCU, CAN transceivers, and power regulators. Use Value: Prevents latch-up or permanent damage to 16 V-rated automotive ICs while maintaining system reset capability after event clearance. |
Use Scenario: Safeguarding IGBT gate drivers and bus voltage monitors in variable-frequency drives subjected to regenerative braking spikes. IC Role / Device Role / Timing Role: Parallel-connected TVS on DC-link capacitor terminals; absorbs 5–10 ms energy bursts exceeding 1 kV/μs slew rate. Use Value: Eliminates need for crowbar SCR circuits, reducing BOM count and enabling automatic recovery without manual fuse replacement. |
| Telecom DC-DC Output Stage | Consumer Appliance Power Input |
Use Scenario: Clamping output transients on 48 V telecom rectifier modules exposed to lightning-induced surges on secondary-side wiring. IC Role / Device Role / Timing Role: Final-stage protector downstream of isolation transformer; clamps common-mode and differential-mode overvoltages simultaneously. Use Value: Maintains EN 61000-4-5 Level 4 compliance (4 kV line-earth) without derating or parallel staging. |
Use Scenario: Surge suppression on AC-DC adapter inputs in white goods (e.g., washing machine control boards) subject to IEC 61000-4-5 Line-to-Ground surges. IC Role / Device Role / Timing Role: First-line defense before primary-side EMI filter; shunts energy before it reaches bridge rectifier and bulk capacitor. Use Value: Extends product lifetime by preventing electrolytic capacitor venting and MOSFET avalanche fatigue during repeated 1.2/50 μs surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Lower PPPM (600 W), smaller SMB package, same VWM (10 V), higher VC (17.0 V @ 32.4 A). | Suitable for board-level signal-line protection; insufficient for automotive load-dump or industrial motor drive energy levels. | Select SMBJ10A only for space-constrained, low-energy applications where peak current remains <50 A. |
| 1.5KE10A | Same VWM (10 V), lower PPPM (1500 W), DO-201 package, higher VC (18.0 V @ 83.3 A), non-AEC-Q101. | Lacks automotive qualification and thermal robustness; limited to commercial-grade power supply outputs. | Choose 1.5KE10A for cost-sensitive consumer designs where AEC-Q101 and 5000 W rating are not required. |
Compared with SMBJ10A and 1.5KE10A, the 5KP10-E3/73 delivers 3.3× and 3.3× higher peak pulse power respectively, supports full automotive qualification, and maintains tighter clamping performance under high-current stress-making it the sole option for ISO 7637-2-compliant front-end protection.

FAQ
What is the clamping voltage of the 5KP10-E3/73 under maximum rated surge current?
The 5KP10-E3/73 exhibits a maximum clamping voltage (VC) of 17.0 V when subjected to its rated peak pulse current (IPPM) of 294 A using the standardized 10/1000 μs waveform. This value is guaranteed per JEDEC test conditions and ensures downstream components rated for 20 V operation remain within safe operating limits during transient events.
Is the 5KP10-E3/73 suitable for automotive applications?
Yes, the 5KP10-E3/73 carries AEC-Q101 qualification, confirming compliance with stress tests including high-temperature operating life, temperature cycling, and humidity bias HAST. Its 175 °C maximum junction temperature and robust P600 package make it appropriate for under-hood and powertrain applications governed by ISO 7637-2.
How does the 5KP10-E3/73 differ from the 5KP10A variant?
The 5KP10-E3/73 is the RoHS-compliant, tape-and-reel packaged version (E3 suffix) with JESD 201 Class 1A whisker resistance, delivered in 13" reels of 800 units (73 = packaging code). The base 5KP10A denotes the generic part number without packaging or qualification suffixes; 5KP10-E3/73 is the exact orderable configuration meeting commercial and automotive sourcing requirements.
What is the reverse leakage current specification for the 5KP10-E3/73 at its stand-off voltage?
At the 10.0 V stand-off voltage (VWM), the 5KP10-E3/73 guarantees a maximum reverse leakage current (ID) of 20 μA at 25 °C. This low leakage preserves efficiency in battery-powered systems and prevents false triggering in high-impedance monitoring circuits connected to protected nodes.
Can the 5KP10-E3/73 be used in bidirectional protection configurations?
No-the 5KP10-E3/73 is unidirectional only, with cathode-band marking indicating polarity. For bidirectional surge suppression, a pair of 5KP10-E3/73 devices must be connected anode-to-anode, or a dedicated bidirectional TVS such as the 5KP10CA should be selected instead.
