Product details
Overview
5KP48-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection on DC power rails and signal lines. It features 48 V stand-off voltage (VWM), 53.3–58.9 V breakdown voltage (VBR) at 5 mA, 77.4 V maximum clamping voltage (VC) at 64.6 A peak pulse current, and 5000 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the 5KP48-E3/54 datasheet, 5KP48-E3/54 pinout, 5KP48-E3/54 application, or 5KP48-E3/54 equivalent, this device is selected for robust overvoltage protection in automotive power supplies, industrial motor drives, telecom line interfaces, and switching regulator outputs where fast response (<1 ns), low clamping ratio, and AEC-Q101 qualification are required.
Technical Context
The 5KP48-E3/54 uses a glass-passivated P600 chip junction optimized for repetitive 10/1000 μs surge events at 0.01% duty cycle. Its unidirectional polarity enables placement in series with positive supply rails to clamp reverse transients while allowing forward conduction during fault conditions.
It operates across -55 °C to +175 °C junction temperature range, supports 500 A IFSM surge current (8.3 ms half-sine), and maintains stable clamping performance due to low incremental surge resistance and 0.106 %/°C VBR temperature coefficient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 48 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system operating margin. |
| VBR (min/max) | 53.3 V / 58.9 V at 5 mA - Confirmed breakdown threshold range; ensures predictable turn-on under surge conditions. |
| VC @ IPPM | 77.4 V at 64.6 A - Clamped voltage during full-rated 5000 W transient; defines worst-case stress on downstream ICs. |
| PPPM | 5000 W - Peak pulse power handling with 10/1000 μs waveform; validates suitability for IEC 61000-4-5 Level 4 surges. |
| IFSM | 500 A - Non-repetitive forward surge current rating (8.3 ms); supports crowbar-style fault clearing in power supplies. |
| TJ max. | +175 °C - Maximum junction temperature; enables use in under-hood automotive and high-ambient industrial environments. |
| Polarity | Unidirectional - Cathode-banded configuration; requires correct orientation in series with positive rail for reverse-transient suppression. |
Pinout & Package
5KP48-E3/54 is housed in a P600 molded epoxy package with matte tin-plated leads. The cathode is marked by a color band on the body. Leads comply with J-STD-002 and JESD 22-B102 solderability standards and support 275 °C solder dip for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; completes clamping loop when transient exceeds VWM. |
| Cathode | High-side connection point | Connected to protected line (e.g., +48 V rail); color band identifies this terminal for correct PCB orientation. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power | Enables single-device protection against severe lightning-induced surges per IEC 61000-4-5 without external crowbar circuitry. |
| AEC-Q101 qualified | Validated for automotive powertrain and chassis applications requiring reliability under thermal cycling, humidity, and vibration stress. |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes overvoltage overshoot during clamping, reducing stress on 50 V-rated MOSFETs and controllers downstream. |
| Fast response time (<1 ns) | Activates before sensitive logic or analog circuitry sustains damage from ESD or inductive switching spikes. |
| UL 94 V-0 molding compound | Ensures flame-retardant enclosure integrity during sustained overvoltage faults or thermal runaway events. |
Applications
| Automotive Power Distribution | Industrial Motor Drive Controls |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ48A-E3/52 | Lower PPPM (600 W), smaller SMB package, same VWM/VBR range, bidirectional option available. | Targeted at board-level signal-line protection rather than bulk power rail clamping. | Select when space-constrained layouts require surface-mount footprint and surge energy is ≤600 W. |
| 1.5KE48A | Same P600 package and 48 V rating, but lower PPPM (1500 W), higher VC (77 V), and no AEC-Q101 qualification. | Suitable for commercial-grade power supplies but not automotive or harsh-environment industrial use. | Choose only for cost-sensitive non-automotive applications where 1500 W surge capability suffices. |
Compared with SMBJ48A-E3/52 and 1.5KE48A, the 5KP48-E3/54 delivers 3.3× higher peak pulse power, AEC-Q101 validation, and tighter clamping control-making it the sole choice for 48 V automotive power distribution and high-reliability industrial DC bus protection.

FAQ
What is the clamping voltage of the 5KP48-E3/54 under full-rated surge current?
The 5KP48-E3/54 exhibits a maximum clamping voltage (VC) of 77.4 V when subjected to its rated peak pulse current of 64.6 A (10/1000 μs waveform). This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuits during worst-case transients. The 5KP48-E3/54 achieves this with low incremental surge resistance, ensuring consistent performance across temperature and aging.
Is the 5KP48-E3/54 RoHS compliant and halogen-free?
Yes, the 5KP48-E3/54 carries the "E3" suffix, indicating full RoHS compliance per Directive 2011/65/EU and halogen-free status per JEDEC JS709A. The device uses matte tin-plated leads and UL 94 V-0 compliant epoxy molding compound. These material attributes are verified in Vishay's official documentation and supported by Vishay's Material Category Policy statements.
Does the 5KP48-E3/54 have AEC-Q101 qualification?
Yes, the 5KP48-E3/54 is AEC-Q101 qualified, as confirmed in the Vishay datasheet (Document Number: 88308, Revision: 20-Nov-12). This qualification covers stress tests including temperature cycling, humidity bias, mechanical shock, and high-temperature operating life-validating its suitability for automotive powertrain and chassis applications.
What is the maximum operating temperature for the 5KP48-E3/54?
The 5KP48-E3/54 has a specified operating junction temperature range of -55 °C to +175 °C. This wide range supports deployment in under-hood automotive environments, industrial enclosures without active cooling, and outdoor telecom equipment. Derating curves in the datasheet define power dissipation limits above 25 °C ambient.
How does the 5KP48-E3/54 differ from the 5KP48A variant?
The 5KP48-E3/54 is the RoHS-compliant, commercial-grade version in 13" paper tape and reel packaging (base code 54, quantity 800). The "HE3" suffix denotes AEC-Q101 qualification; "E3" alone confirms RoHS compliance and JESD 201 Class 1A whisker resistance. Both share identical electrical specs, but only HE3-labeled units carry automotive qualification evidence.
