Product details
Overview
5KP70-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection of DC power rails and signal lines. It features 5000 W peak pulse power (10/1000 µs), 70 V stand-off voltage (VWM), 77.8–86.0 V breakdown voltage (VBR), and clamps transients to ≤113 V at 44.2 A peak pulse current - used in automotive power supply output stages and industrial motor drive DC bus protection.
For engineers reviewing the 5KP70-E3/54 datasheet, 5KP70-E3/54 pinout, 5KP70-E3/54 application, or 5KP70-E3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, P600 mechanical dimensions, clamping performance under standardized surge waveforms, and validated alternatives for overvoltage protection design-in.
Technical Context
This TVS diode operates as a voltage-clamping device in parallel with protected circuitry, entering avalanche conduction when reverse voltage exceeds VBR. Its glass-passivated P600 junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing inductive switching spikes and lightning-induced surges on 48 V–72 V systems.
Rated for 175 °C maximum junction temperature and qualified to AEC-Q101, the 5KP70-E3/54 supports automotive-grade reliability. Its 2.0 µA max reverse leakage at 70 V and 0.108 %/°C VBR temperature coefficient ensure stable clamping across wide thermal operating ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 70 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 48 V or 60 V systems. |
| VBR (min/max) | 77.8 V / 86.0 V at 5.0 mA - Confirmed avalanche onset range; ensures predictable turn-on without premature conduction. |
| VC @ IPPM | ≤113 V at 44.2 A - Clamped voltage during 5000 W 10/1000 µs surge; limits downstream component stress to safe levels. |
| PPPM | 5000 W - Peak pulse power handling per JEDEC standard; supports single-event surge immunity up to Level 4 IEC 61000-4-5. |
| IFSM | 500 A - Non-repetitive forward surge rating (8.3 ms half-sine); enables crowbar-like fault containment without fuse blow delay. |
| TJ max | 175 °C - Maximum junction temperature; allows operation in under-hood automotive environments and high-ambient industrial enclosures. |
| Leakage @ VWM | ≤2.0 µA - Ultra-low reverse leakage preserves system efficiency and avoids false triggering in high-impedance sensing paths. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; cathode indicated by color band; RoHS-compliant (E3 suffix); UL 94 V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction or surge clamping | Connected to lower-potential side (e.g., ground or return path); must handle 500 A surge without bond wire failure. |
| Cathode | Current exit terminal during reverse-biased clamping | Connected to protected line (e.g., +70 V rail); color band identifies polarity; determines clamping threshold direction. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 µs) | Enables robust protection against severe lightning surges (IEC 61000-4-5 4 kV/2 Ω) on 48 V–72 V DC buses without derating. |
| AEC-Q101 qualified (HE3 variant; E3 meets commercial spec) | Validates reliability for automotive powertrain and body electronics applications requiring extended temperature cycling and humidity exposure. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., MOSFET switching noise), improving clamping precision. |
| 175 °C junction temperature rating | Supports placement near heat-generating components (e.g., DC-DC converters) without thermal derating penalties. |
| UL 94 V-0 flammability compliant epoxy | Meets safety standards for enclosed industrial and automotive control units where flame propagation risk must be eliminated. |
Applications

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 SMAJ70A | Lower peak power (400 W), SMA package (0.5 W steady-state), 70 V VWM, 77.8–86.0 V VBR | Suitable only for low-energy signal-line protection; cannot replace 5KP70-E3/54 in power rail applications due to 12.5× lower PPPM. | Select only for space-constrained PCBs where surge energy is limited to <500 W and thermal mass is insufficient for P600 mounting. |
| ON Semiconductor 1.5KE70A | Same 5000 W rating, DO-201 package, 70 V VWM, 77.8–86.0 V VBR, but 175 °C TJ and no AEC-Q101 qualification | Acceptable for industrial/commercial use but not automotive; smaller package reduces thermal mass and surge endurance margin. | Choose when AEC-Q101 is not required and board layout restricts P600 footprint; verify thermal derating at 125 °C ambient. |
Compared with SMAJ70A and 1.5KE70A, the 5KP70-E3/54 uniquely combines 5000 W surge capacity, P600 thermal robustness, and commercial-grade reliability in a single through-hole package - making it the preferred choice for high-energy DC bus protection where sustained power dissipation and mechanical ruggedness are mandatory.

FAQ
What is the clamping voltage of the 5KP70-E3/54 under full-rated surge conditions?
The 5KP70-E3/54 clamps to a maximum of 113 V when subjected to its rated 44.2 A peak pulse current (10/1000 µs waveform). This value is measured per JEDEC standards and represents the upper limit of voltage seen by protected circuitry during a 5000 W transient event. The actual clamping voltage of the 5KP70-E3/54 will be lower at reduced surge currents, scaling predictably with the device's dynamic impedance.
Is the 5KP70-E3/54 suitable for automotive applications?
The 5KP70-E3/54 is RoHS-compliant and manufactured to commercial-grade specifications. While its base P/N-E3 variant is not AEC-Q101 qualified, the related 5KP70AHE3/54 (HE3 suffix) is fully AEC-Q101 qualified. Engineers specifying the 5KP70-E3/54 for automotive use should confirm whether AEC-Q101 compliance is mandatory for their application tier; if so, the HE3 version of the 5KP70-E3/54 must be selected instead.
What does the "/54" in 5KP70-E3/54 indicate?
The "/54" suffix in 5KP70-E3/54 denotes the preferred package code per Vishay's ordering nomenclature, specifying that the device is supplied in 13-inch diameter paper tape and reel packaging with a base quantity of 800 units. This format enables automated pick-and-place assembly and is distinct from bulk or ammo-pack options. The 5KP70-E3/54 is not a variant or revision - it is the standard production configuration of the 5KP70-E3/54.
Can the 5KP70-E3/54 be used in bidirectional configurations?
No - the 5KP70-E3/54 is explicitly specified as unidirectional only, with cathode marked by a color band. It conducts in avalanche breakdown only when reverse-biased above VBR; forward conduction is limited to the 3.5 V instantaneous forward voltage at 100 A. For bidirectional surge protection, two 5KP70-E3/54 devices must be connected in series opposition, or a dedicated bidirectional TVS such as the 5KP70CA should be selected instead.
What is the thermal resistance junction-to-lead (RθJL) for the 5KP70-E3/54?
Vishay does not publish RθJL for the 5KP70-E3/54 in the 88308 datasheet. Instead, thermal performance is characterized via the power derating curve (Fig. 5), which shows 8.0 W dissipation at TL = 75 °C on an infinite heatsink. For PCB-level thermal design, engineers should follow Vishay's recommended P600 mounting guidelines - including minimum copper area (≥1 in² per lead) and thermal vias - to achieve adequate heat spreading. The 5KP70-E3/54 relies on lead-frame conduction rather than case-to-ambient metrics.
