Product details
Overview
5KP6.5A-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection. It features 5000 W peak pulse power (10/1000 μs), 6.5 V stand-off voltage (VWM), and clamps transients to ≤11.2 V at 446 A peak pulse current - deployed on DC power rails of industrial switching supplies and automotive ECUs.
For engineers reviewing the 5KP6.5A-E3/54 datasheet, 5KP6.5A-E3/54 pinout, 5KP6.5A-E3/54 application, or 5KP6.5A-E3/54 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 175 °C max junction temperature, RoHS-compliant matte tin leads, and P600 mechanical robustness for high-reliability board-level surge suppression.
Technical Context
This TVS diode operates as a voltage-clamping device triggered by overvoltage events exceeding its 6.5 V stand-off threshold. Its glass-passivated P600 chip junction enables fast response (<1 ns) and low incremental surge resistance, ensuring precise clamping during 10/1000 μs transients without thermal runaway.
It is rated for 5000 W peak pulse power with 0.01 % duty cycle, 8.0 W steady-state power dissipation on infinite heatsink at 75 °C, and withstands 600 A non-repetitive forward surge (8.3 ms half-sine). The cathode is marked by a color band; terminals are solderable per J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR min/max | 7.22 V / 7.98 V at 50 mA - Verified breakdown range ensures reliable triggering margin above VWM |
| VC @ IPPM | ≤11.2 V at 446 A - Clamping voltage defines worst-case overvoltage seen by protected circuitry |
| PPPM | 5000 W (10/1000 μs) - Sustains high-energy surges common in automotive load-dump and industrial switching noise |
| IFSM | 600 A (8.3 ms half-sine) - Withstands repetitive inrush or fault currents without bond-wire failure |
| TJ max | +175 °C - Enables operation in under-hood automotive and high-ambient industrial environments |
| Polarity | Unidirectional - Protects only against positive transients on anode-to-cathode bias; requires correct orientation |
Pinout & Package
Package: P600 - Molded epoxy body with glass-passivated junction, UL 94 V-0 rated, 0.375" (9.5 mm) body length, matte tin-plated leads. Cathode denoted by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point during clamping | Connected to protected line (e.g., +12 V rail); conducts surge current toward ground path |

IC Role / Device Role / Timing Role: Parallel-connected TVS across motor terminals or H-bridge output nodes to divert flyback energy. Use Value: Withstands 600 A surge (8.3 ms) and 175 °C ambient - ensures reliability in thermally constrained appliance enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5A | Lower peak power (600 W), smaller SMB package, same VWM/VC specs | Not suitable for ISO 7637-2 Pulse 5a; limited to lower-energy IEC 61000-4-2/4-5 Level 2 | Select when board space is constrained and surge energy is ≤600 W - verify clamping margin with actual waveform testing. |
| 1.5KE6.8A | Same P600 package, 1500 W peak power, slightly higher VWM (6.8 V), lower VC (10.5 V) | Lacks AEC-Q101 qualification; not rated for automotive under-hood use | Choose for cost-sensitive industrial power supplies where AEC-Q101 is not required and 1500 W suffices. |
Compared with SMBJ6.5A and 1.5KE6.8A, the 5KP6.5A-E3/54 delivers 3.3× higher surge capacity than SMBJ6.5A and 3.3× more robust automotive qualification than 1..5KE6.8A - making it the sole option for full-load-dump protection in AEC-Q101–mandated systems.

FAQ
What is the maximum clamping voltage of the 5KP6.5A-E3/54 under peak pulse conditions?
The 5KP6.5A-E3/54 has a maximum clamping voltage (VC) of 11.2 V when subjected to its rated peak pulse current of 446 A using a 10/1000 μs waveform. This value is guaranteed per JEDEC-registered test conditions at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during surge events. The 5KP6.5A-E3/54 maintains this clamping performance across its operational temperature range due to its low temperature coefficient of VBR (0.065 %/°C).
Is the 5KP6.5A-E3/54 suitable for automotive applications?
Yes, the 5KP6.5A-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments up to +175 °C junction temperature. Its P600 package passes mechanical and thermal stress tests per AEC-Q101, and its 5000 W peak pulse rating meets ISO 7637-2 Pulse 5a (load dump) requirements. The 5KP6.5A-E3/54 is commonly deployed in engine control units, body control modules, and ADAS power supplies where robust transient immunity is mandatory.
What does the "-E3/54" suffix indicate in 5KP6.5A-E3/54?
The "-E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD 201 Class 1A whisker resistance. The "/54" indicates the preferred package code for tape-and-reel delivery: 13-inch diameter paper tape, 800 units per reel. This ordering format ensures consistent handling in automated SMT assembly and guarantees compliance with lead-free soldering profiles up to 275 °C for 10 seconds.
How does the 5KP6.5A-E3/54 differ from bidirectional TVS diodes?
The 5KP6.5A-E3/54 is unidirectional - it conducts only during positive voltage transients applied anode-to-cathode and blocks reverse voltage up to its VWM of 6.5 V. Bidirectional TVS diodes (e.g., 5KP6.5CA) protect both polarities but exhibit higher leakage and reduced surge capacity per unit area. The 5KP6.5A-E3/54's unidirectional architecture delivers tighter clamping (VC = 11.2 V) and better DC blocking for single-polarity DC rails, making it optimal for 12 V/24 V automotive and industrial power systems.
Can the 5KP6.5A-E3/54 replace a 1.5KE6.8A in an existing design?
The 5KP6.5A-E3/54 shares the P600 package and similar VWM/VC values with the 1.5KE6.8A but offers 3.3× higher peak pulse power (5000 W vs. 1500 W) and AEC-Q101 qualification. Physical replacement is possible due to identical footprint and polarity marking, but designers must verify PCB thermal relief and grounding paths can handle the higher surge energy. The 5KP6.5A-E3/54 is not a drop-in substitute unless the original design margin accommodates its superior clamping and energy absorption - always validate with actual surge testing.
