Product details
Overview
5KP90-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal paths. It features a 90 V stand-off voltage (VWM), 100–111 V breakdown voltage (VBR), 5000 W peak pulse power (10/1000 μs), 34.2 A peak pulse current (IPPM), and clamps to ≤146 V at rated surge, making it suitable for protecting MOSFETs and ICs in industrial power supplies.
For engineers reviewing the 5KP90-E3/73 datasheet, 5KP90-E3/73 pinout, 5KP90-E3/73 application, or 5KP90-E3/73 equivalent, key selection considerations include its P600 package thermal performance, unidirectional polarity, AEC-Q101 qualification (E3 suffix denotes commercial grade; HE3 required for automotive), 175 °C max junction temperature, and 2.0 μA reverse leakage at 90 V.
Technical Context
This TVS diode operates as a voltage-clamping device in parallel with protected circuitry, entering avalanche conduction when transient voltage exceeds its breakdown threshold. Its glass-passivated P600 chip junction enables low incremental surge resistance and fast response (<1 ns), critical for suppressing inductive switching spikes and lightning-induced surges on 48–96 V DC rails.
The 5KP90-E3/73 is rated for non-repetitive 10/1000 μs waveform pulses at 0.01% duty cycle, with derating above 25 °C ambient per Fig. 2. It supports soldering up to 275 °C for 10 s (JESD 22-B106) and meets UL 94 V-0 flammability requirements via molded epoxy encapsulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 90 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin. |
| VBR @ IT=5 mA | 100–111 V - Breakdown voltage range at 5 mA test current; ensures reliable turn-on during overvoltage events. |
| IPPM (10/1000 μs) | 34.2 A - Peak surge current capability; determines maximum energy absorption without failure (5 kW). |
| VC @ IPPM | ≤146 V - Clamped voltage under full-rated surge; sets upper limit of stress on downstream components. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in high-ambient industrial environments. |
| Polarity | Unidirectional - Cathode-banded configuration; protects against positive transients only; requires correct orientation in circuit. |
| Package | P600 - Axial-leaded, 9.5 mm body length; provides mechanical robustness and thermal mass for transient energy dissipation. |
Pinout & Package
The 5KP90-E3/73 is housed in a P600 axial-leaded package with matte tin-plated leads. The cathode is marked by a color band; the anode is the unmarked lead. Leads comply with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded lead) | Current entry during forward conduction | Connected to lower-potential side (e.g., ground or return path); not used in normal reverse-biased protection mode. |
| Cathode (banded lead) | Current exit during avalanche clamping | Connected to protected line (e.g., +90 V rail); conducts surge current to ground when VLINE > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Enables protection against high-energy transients such as ISO 7637-2 Pulse 5a (load dump) in 24 V systems. |
| AEC-Q101 qualified variant available (HE3 suffix) | Confirms reliability for automotive under-hood applications; E3 suffix is commercial-grade only. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients, improving clamping precision and system immunity. |
| UL 94 V-0 compliant epoxy molding | Ensures flame retardancy in safety-critical industrial enclosures and power supply housings. |
| 175 °C maximum junction temperature | Supports mounting on heatsinks or high-temperature PCB zones without thermal derating penalties. |
Applications
| Industrial Power Supply Protection | Automotive ECUs |
|---|---|

IC Role / Device Role / Timing Role: Unidirectional shunt protector on 12 V or 24 V supply input, triggered within nanoseconds of overvoltage onset. Use Value: Maintains functional safety integrity by clamping transients below 146 V while surviving repeated 10/1000 μs surges per AEC-Q101 stress profiles. |
| Telecom Line Card Surge Suppression | Renewable Energy Inverter DC Link |
Use Scenario: Shielding Ethernet PHY power rails and RS-485 interface lines in outdoor base station line cards from lightning-induced surges. IC Role / Device Role / Timing Role: Primary-level TVS on 3.3 V/5 V auxiliary supplies, coordinated with secondary GDT or MOV stages.

IC Role / Device Role / Timing Role: Parallel-connected TVS on 600–1000 V DC bus to clamp switching spikes and prevent false triggering of overvoltage protection. Use Value: Withstands 175 °C junction temperature and delivers stable clamping performance across wide temperature ranges typical of rooftop installations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ90A | Lower peak power (600 W), SMC package, same VWM (90 V), higher VC (146 V → 156 V) | Not suitable for 5 kW surge events; limited to low-energy data-line or sub-100 W power rail protection. | Select SMBJ90A only when board space is constrained and surge energy is <100 mJ; verify thermal design for repeated surges. |
| 1.5KE91A | Same P600 package, 5 kW rating, but older 1.5 kW series designation; VWM = 91 V, VC = 146 V, IPPM = 34.2 A - functionally identical clamping behavior | No AEC-Q101 qualification; RoHS compliance may differ per date code; legacy part with longer lead times. | 1.5KE91A is a direct functional alternative with identical electrical specs; prefer 5KP90-E3/73 for new designs due to updated manufacturing and traceability. |
Compared with SMBJ90A and 1.5KE91A, the 5KP90-E3/73 offers superior surge handling (5 kW vs. 600 W) and modern process control, while matching 1.5KE91A's clamping performance but with enhanced reliability documentation and commercial-grade traceability.

FAQ
What is the maximum clamping voltage of the 5KP90-E3/73 under full-rated surge conditions?
The 5KP90-E3/73 clamps to a maximum of 146 V when subjected to its rated 34.2 A peak pulse current (10/1000 μs waveform). This value is guaranteed per JEDEC test conditions and represents the highest voltage seen across the device during worst-case surge events, ensuring downstream components remain within safe operating limits. The 5KP90-E3/73 achieves this with low incremental resistance and fast avalanche response.
Is the 5KP90-E3/73 suitable for automotive applications?
The 5KP90-E3/73 carries the E3 suffix, indicating RoHS-compliant commercial-grade qualification. While it shares the same P600 package and electrical specs as the AEC-Q101-qualified 5KP90HE3/73, the 5KP90-E3/73 itself is not AEC-Q101 certified. For automotive under-hood use, specify the HE3 variant; the 5KP90-E3/73 is appropriate for industrial, telecom, and consumer applications where AEC-Q101 is not mandated.
How does the 5KP90-E3/73 compare to standard Zener diodes in surge protection roles?
Unlike general-purpose Zener diodes, the 5KP90-E3/73 is optimized for high-energy transient suppression: it handles 5000 W peak pulse power (vs. typically <5 W for Zeners), exhibits nanosecond response, and maintains stable clamping under repetitive surges. Its glass-passivated junction and P600 thermal mass enable reliable operation where Zeners would fail catastrophically. The 5KP90-E3/73 is not a voltage regulator - it is a dedicated transient suppressor.
What is the meaning of the "/73" suffix in 5KP90-E3/73?
The "/73" in 5KP90-E3/73 is a Vishay internal packaging code denoting tape-and-reel delivery in 13-inch diameter reels with a base quantity of 800 units. It does not affect electrical specifications or reliability. The "E3" portion confirms RoHS compliance and commercial-grade qualification; "/73" solely identifies the packaging format and is used for logistics and inventory tracking by distributors and OEMs ordering the 5KP90-E3/73.
Can the 5KP90-E3/73 be used in bidirectional configurations?
No - the 5KP90-E3/73 is strictly unidirectional, with cathode indicated by a color band. It protects against positive-going transients only. For bidirectional surge protection (e.g., AC lines or differential data buses), two 5KP90-E3/73 devices must be connected in series opposition, or a purpose-built bidirectional TVS such as the 5KP90CA should be selected. Using a single 5KP90-E3/73 in reverse bias beyond its 90 V stand-off risks permanent breakdown.
