Product details
Overview
5KP54HE3/54 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 54 V standoff voltage (VWM), 60–66.3 V breakdown range (VBR), 5000 W peak pulse power (10/1000 μs), 57.4 A peak pulse current (IPPM), and clamps to ≤87.1 V at rated surge - used in automotive power supply output stages and industrial sensor interface protection.
For engineers reviewing the 5KP54HE3/54 datasheet, 5KP54HE3/54 pinout, 5KP54HE3/54 application, or 5KP54HE3/54 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 175 °C max junction temperature, low incremental surge resistance, and compatibility with 13" paper tape & reel delivery for automated SMT assembly.
Technical Context
The 5KP54HE3/54 employs a glass-passivated P600 chip junction optimized for fast response (<1 ns) to ESD and lightning-induced transients. Its unidirectional structure provides forward conduction capability up to 600 A IFSM, enabling crowbar-like overvoltage shutdown without external triggering circuitry.
It operates within -55 °C to +175 °C junction temperature range and maintains stable clamping performance under repetitive 0.01% duty cycle surges. The device meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 2 whisker resistance, confirming suitability for automotive-grade reflow and long-term reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 54 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 48 V systems. |
| VBR @ IT=50 mA | 60.0–66.3 V - measured breakdown range ensures consistent turn-on across production lots and temperature. |
| IPPM (10/1000 μs) | 57.4 A - peak surge current handling capacity determines minimum trace width and fuse coordination in protection circuits. |
| VC @ IPPM | ≤87.1 V - clamping voltage limits downstream IC stress during worst-case surge; critical for 75 V-rated MOSFET gate drivers. |
| PPPM | 5000 W - peak pulse power rating validates use in high-energy switching supply outputs and motor drive feedback paths. |
| TJ max | +175 °C - enables operation in under-hood automotive environments and sealed industrial enclosures without derating. |
| AEC-Q101 | Qualified - confirms reliability validation per automotive electronics stress test standard, including temperature cycling and HTRB. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; cathode denoted by color band; RoHS-compliant and UL 94 V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path | Connected to system ground or low-side return; enables bidirectional surge shunting when paired with complementary devices. |
| Cathode | Reverse-biased clamping node | Connected to protected line (e.g., 48 V rail); initiates avalanche conduction above VWM to clamp transients. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Supports single-event surge suppression in 48 V automotive power distribution without cascaded protection stages. |
| AEC-Q101 qualified | Validated for automotive under-hood applications including engine control modules and ADAS power supplies. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 5a), improving system-level immunity margin. |
| 175 °C maximum junction temperature | Enables direct mounting on high-temperature PCB areas near power converters without thermal derating penalties. |
| Matte tin plating, J-STD-002 compliant | Ensures reliable solder joint formation in lead-free reflow profiles up to 260 °C peak temperature. |
Applications
| Automotive Power Supply Output Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 48 V DC-DC converter outputs against load dump and alternator surge per ISO 16750-2. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between output rail and chassis ground to clamp transients exceeding 54 V. Use Value: Limits peak voltage to ≤87.1 V during 5000 W surges, preventing damage to downstream PMICs and microcontrollers. |

IC Role / Device Role / Timing Role: Low-capacitance (<100 pF) unidirectional suppressor on differential feedback traces referenced to 54 V bus. Use Value: Clamps common-mode spikes to ≤87.1 V while adding negligible signal distortion due to fast recovery and low CJ. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ54A-E3/52 | Lower peak power (600 W), smaller SMB package, same 54 V VWM, but lower IPPM (12.3 A). | Suitable for board-level signal line protection, not main power rail clamping. | Select when space-constrained layouts require surface-mount footprint and surge energy is ≤600 W. |
| 1.5KE56A | Same P600 package, 56 V VWM, 5000 W rating, but not AEC-Q101 qualified and higher VC (93.6 V). | Limited to commercial/industrial use; lacks automotive reliability validation. | Choose only for non-automotive applications where AEC-Q101 is not mandated and higher clamping voltage is acceptable. |
Compared with SMBJ54A-E3/52 and 1.5KE56A, the 5KP54HE3/54 delivers superior surge robustness (5000 W), automotive qualification, and tighter clamping (87.1 V), making it the preferred choice for primary DC rail protection in harsh environments.

FAQ
What is the clamping voltage of the 5KP54HE3/54 under full-rated surge conditions?
The 5KP54HE3/54 clamps to a maximum of 87.1 V when subjected to its rated 57.4 A peak pulse current (10/1000 μs waveform). This value is guaranteed per JEDEC test conditions and represents the upper limit of voltage seen by downstream components during worst-case transient events. The 5KP54HE3/54 achieves this clamping performance while maintaining low incremental surge resistance for minimal overshoot.
Is the 5KP54HE3/54 suitable for automotive applications?
Yes, the 5KP54HE3/54 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and ADAS power supplies. Its 175 °C maximum junction temperature, robust P600 package, and validated reliability under temperature cycling and high-humidity bias stress make it appropriate for under-hood and cabin-mounted systems. The 5KP54HE3/54 also meets JESD 201 Class 2 whisker resistance requirements.
What does the "HE3" suffix indicate in 5KP54HE3/54?
The "HE3" suffix denotes that the 5KP54HE3/54 is RoHS-compliant and AEC-Q101 qualified, with matte tin-plated leads meeting JESD 201 Class 2 whisker resistance. This distinguishes it from the "E3" variant (commercial grade, JESD 201 Class 1A). The "/54" indicates the preferred package code for 13" paper tape and reel delivery with 800 units per reel - a configuration confirmed in Vishay's ordering information table for the 5KP54HE3/54.
How does the 5KP54HE3/54 compare to standard Zener diodes in surge protection?
Unlike standard Zener diodes, the 5KP54HE3/54 is engineered for high-energy transient suppression with 5000 W peak pulse power handling, low dynamic impedance, and fast response (<1 ns). Standard Zeners lack specified surge ratings and degrade rapidly under repetitive transients. The 5KP54HE3/54 uses glass-passivated junction technology and P600 packaging to sustain repeated 10/1000 μs surges at 0.01% duty cycle - a capability not offered by general-purpose Zener diodes.
Can the 5KP54HE3/54 be used in bidirectional configurations?
No, the 5KP54HE3/54 is unidirectional only, as explicitly stated in the Vishay datasheet. For bidirectional transient protection, two 5KP54HE3/54 devices must be connected in series opposition (anode-to-anode or cathode-to-cathode), or a dedicated bidirectional TVS such as 5KP54CA should be selected. Using a single 5KP54HE3/54 in reverse-biased AC applications will result in forward conduction and potential failure.
