Product details
Overview
5KP9.0A-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for primary overvoltage protection of DC power rails and signal lines. It features 9.0 V stand-off voltage (VWM), 10.0–11.1 V breakdown voltage (VBR) at 5 mA, 5000 W peak pulse power (10/1000 μs), 325 A peak pulse current (IPPM), and clamps to ≤15.4 V at rated surge - used in automotive power supply input stages and industrial motor drive DC bus protection.
For engineers reviewing the 5KP9.0A-E3/54 datasheet, 5KP9.0A-E3/54 pinout, 5KP9.0A-E3/54 application, or 5KP9.0A-E3/54 equivalent, key selection criteria include unidirectional polarity, P600 through-hole mounting, AEC-Q101 qualification (via HE3 variant), 175 °C max junction temperature, and compliance with JEDEC registered electrical characteristics for high-energy transients.
Technical Context
The 5KP9.0A-E3/54 operates as a silicon avalanche diode with glass-passivated P600 chip junction, delivering fast response (<1 ns) and low incremental surge resistance to clamp voltage spikes before downstream components are damaged. Its 10/1000 μs waveform rating reflects standardized lightning and inductive-switching surge immunity testing per IEC 61000-4-5 and ANSI/IEEE C62.35.
Designed for non-repetitive surge events at ≤0.01% duty cycle, it sustains 500 A forward surge (8.3 ms half-sine) and dissipates 8.0 W continuously on infinite heatsink at TL = 75 °C. Thermal derating above 25 °C follows Fig. 2, and clamping performance remains stable across -55 °C to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - maximum continuous reverse voltage before leakage exceeds 20 μA; sets DC rail operating margin. |
| VBR min/max | 10.0 V / 11.1 V at IT = 5 mA - defines precise avalanche onset window for predictable clamping threshold. |
| VC @ IPPM | ≤15.4 V at 325 A - peak clamped voltage during 5000 W transient; determines protected circuit's maximum stress level. |
| PPPM | 5000 W (10/1000 μs) - energy-handling capacity for lightning-induced surges per IEC 61000-4-5 Level 4. |
| TJ max | +175 °C - enables operation in under-hood automotive and high-ambient industrial environments without thermal shutdown. |
| IFSM | 500 A (8.3 ms half-sine) - withstands high-current inrush or fault currents long enough for fuse/breaker coordination. |
| Polarity | Unidirectional - cathode marked by color band; suitable for DC-biased protection only, not AC line applications. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; UL 94 V-0 rated; RoHS compliant (E3 suffix); 0.375" (9.5 mm) body length; lead diameter 0.048–0.052" (1.22–1.32 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry during forward conduction or surge clamping | Connected to protected line (e.g., +12 V rail); must be routed with low-inductance path to ground reference. |
| Cathode | Current exit during reverse-biased clamping | Marked by color band; tied to system ground or low-impedance return plane to minimize clamping overshoot. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified variant available | HE3 suffix version meets automotive reliability standards for engine control, body electronics, and ADAS power inputs. |
| 5000 W peak pulse power | Handles 10/1000 μs surges up to 325 A - sufficient for ISO 7637-2 Pulse 5a (load dump) and IEC 61000-4-5 Combination Wave. |
| Low clamping ratio (VC/VBR ≈ 1.5) | 15.4 V clamping at 325 A vs. 10.5 V typical VBR ensures minimal overvoltage stress on 12 V-rated ICs and MOSFETs. |
| Fast response time & low dynamic impedance | Sub-nanosecond turn-on and <0.05 Ω incremental surge resistance limit voltage overshoot during fast-rising transients. |
| P600 mechanical robustness | High thermal mass and UL 94 V-0 epoxy enable reliable soldering (275 °C, 10 s) and mechanical stability in vibration-prone environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0A | Lower PPPM (600 W), SMC package (surface-mount), 10.0–11.1 V VBR same, but IPPM = 62 A | Targeted for PCB space-constrained designs; insufficient for ISO 7637-2 Pulse 5a or IEC 61000-4-5 Level 4 | Select SMBJ9.0A only when surge energy is ≤600 W and board layout favors SMT over through-hole P600. |
| 1.5KE9.1A | Same P600 package, 9.1 V VWM, but lower PPPM (1500 W), IPPM = 129 A, VC = 14.5 V at 129 A | Lacks AEC-Q101 qualification; suitable for commercial/industrial use only, not automotive-grade systems | Choose 1.5KE9.1A where cost sensitivity outweighs automotive qualification and 5000 W surge headroom is unnecessary. |
Compared with SMBJ9.0A and 1.5KE9.1A, the 5KP9.0A-E3/54 delivers triple the pulse power of the former and over three times that of the latter - making it the sole option among the three qualified for full automotive load dump and industrial lightning surge standards without external heat sinking.

FAQ
What is the maximum clamping voltage of the 5KP9.0A-E3/54 during a 5000 W surge event?
The 5KP9.0A-E3/54 clamps to a maximum of 15.4 V when subjected to its rated peak pulse current of 325 A (10/1000 μs waveform). This value is measured per JEDEC test conditions and represents the upper limit of voltage seen by downstream components during worst-case transient events - critical for ensuring compatibility with 16 V absolute maximum-rated ICs.
Is the 5KP9.0A-E3/54 suitable for automotive applications requiring AEC-Q101 qualification?
The 5KP9.0A-E3/54 itself carries the commercial-grade E3 suffix and is not AEC-Q101 qualified. However, Vishay offers the functionally identical 5KP9.0AHE3_A/C variant (HE3 suffix) which is fully AEC-Q101 qualified. Engineers designing for automotive use must specify the HE3 version - the E3 variant is intended for industrial and commercial applications only.
How does the 5KP9.0A-E3/54 differ from standard Zener diodes in overvoltage protection?
Unlike general-purpose Zener diodes, the 5KP9.0A-E3/54 is optimized for high-energy transient suppression: it handles 5000 W peak pulses (vs. <1 W for most Zeners), features low dynamic impedance for tight clamping, and uses glass-passivated P600 construction for robust thermal and mechanical performance. Its 10/1000 μs rating and JEDEC registration confirm suitability for standardized surge immunity testing - not achievable with standard Zener parts.
Can the 5KP9.0A-E3/54 be used in AC line applications?
No - the 5KP9.0A-E3/54 is unidirectional and rated only for DC or polarity-defined circuits. Its cathode-band marking and lack of bidirectional symmetry make it unsuitable for AC line protection. For AC applications, bidirectional TVS diodes such as the 5KP9.0CA or dedicated MOVs must be selected instead.
What is the recommended PCB layout practice for optimal performance of the 5KP9.0A-E3/54?
To maximize effectiveness, route the 5KP9.0A-E3/54 with minimum trace length between anode and protected line, and cathode and low-impedance ground plane - ideally using wide copper pours and multiple vias to ground. Avoid routing near noisy switching nodes; place it as close as possible to the connector or power entry point to intercept transients before they propagate into the system.
