Product details
Overview
5KP75A-E3/54 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 75 V standoff voltage (VWM), 83.3–92.1 V breakdown voltage (VBR), 5000 W peak pulse power (10/1000 μs), 41.3 A peak pulse current (IPPM), and clamps to ≤121 V at rated surge - used in automotive power supplies, industrial motor drives, and telecom interface protection.
For engineers reviewing the 5KP75A-E3/54 datasheet, 5KP75A-E3/54 pinout, 5KP75A-E3/54 application, or 5KP75A-E3/54 equivalent, key selection criteria include unidirectional polarity, P600 package thermal performance, AEC-Q101 qualification status, clamping voltage margin versus protected IC VDS/VIN ratings, and 175 °C max junction temperature for under-hood deployment.
Technical Context
This TVS operates as a voltage-clamping device triggered by reverse-biased avalanche breakdown above VBR, with low incremental surge resistance (typ. <1 Ω) ensuring minimal overshoot during fast transients. Its glass-passivated P600 chip junction enables stable 5000 W surge handling at 0.01% duty cycle without degradation.
The device exhibits a +0.108 %/°C temperature coefficient of VBR, enabling predictable clamping shift across -55 °C to +175 °C operation. It meets JESD 22-B106 solder dip (275 °C, 10 s) and JESD 201 Class 1A whisker testing, confirming robustness for automated assembly and harsh-environment reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 75.0 V - Maximum continuous reverse operating voltage before leakage exceeds 2 μA; sets upper limit for protected circuit DC rail. |
| VBR @ IT = 5 mA | 83.3–92.1 V - Measured breakdown range defining reliable avalanche initiation threshold; ensures consistent turn-on across production lot. |
| IPPM (10/1000 μs) | 41.3 A - Peak surge current capability at rated waveform; determines minimum system fuse/breaker coordination time. |
| VC @ IPPM | ≤121 V - Clamped voltage during full-rated surge; must remain below absolute maximum rating of downstream MOSFET or IC. |
| PPPM | 5000 W - Peak pulse power dissipation capacity; defines single-event energy absorption limit (5 J at 1000 μs tail). |
| TJ max | +175 °C - Maximum junction temperature; supports placement near heat-generating components in engine control units. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD per AEC standard; required for powertrain modules. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; cathode denoted by color band; UL 94 V-0 compliant; 9.5 mm body length; lead spacing 8.6 mm; suitable for through-hole mounting on 2 oz copper PCBs with thermal relief pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path / surge return node | Connected to ground or low-impedance return plane; carries full surge current during clamping event. |
| Cathode | Protected line connection / high-side clamp node | Connected to line being protected (e.g., 48 V battery rail); voltage referenced to anode during transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Enables single-device protection against ISO 7637-2 Pulse 5a (load dump) up to 120 V, eliminating need for multi-stage clamping networks. |
| AEC-Q101 qualification | Validates suitability for automotive power electronics including ADAS ECUs, body controllers, and charging interfaces without additional qualification effort. |
| Low incremental surge resistance | Minimizes VPP overshoot during fast-rising transients (<1 ns rise time), improving immunity to EFT/burst events per IEC 61000-4-4. |
| 175 °C maximum junction temperature | Supports direct mounting on high-temperature PCB zones (e.g., near DC-DC converters in EV onboard chargers) without derating. |
| Unidirectional polarity only | Simplifies layout vs. bidirectional devices; eliminates ambiguity in cathode/anode routing for DC-biased rails like CAN FD or LIN bus power domains. |

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 SMAJ75A | Same 75 V VWM, but lower 400 W PPPM; SMA package limits thermal mass and surge endurance. | Not suitable for automotive load dump; limited to low-energy signal-line protection (e.g., USB, RS-485). | Select only for space-constrained consumer electronics where 5000 W capability is unnecessary. |
| ON Semiconductor 1.5KE75A | Same 75 V VWM and P600 package, but 1500 W PPPM; higher clamping voltage (129 V) and no AEC-Q101 qualification. | Acceptable for industrial AC-DC supplies but excluded from automotive safety-critical systems. | Choose when cost sensitivity outweighs automotive compliance and high-energy surge margin requirements. |
Compared with SMAJ75A and 1.5KE75A, the 5KP75A-E3/54 delivers 3.3× and 3.3× higher peak pulse power respectively, maintains AEC-Q101 qualification for automotive use, and achieves tighter clamping (121 V vs. ≥129 V), directly enabling higher system voltage margins and longer component lifetime under repetitive surge stress.

FAQ
What is the maximum clamping voltage of the 5KP75A-E3/54 under full-rated surge conditions?
The 5KP75A-E3/54 clamps to a maximum of 121 V when subjected to its rated 41.3 A peak pulse current (10/1000 μs waveform). This value is guaranteed across the full operating temperature range and is critical for ensuring downstream components - such as 150 V-rated MOSFETs or 130 V-input DC-DC converters - remain within absolute maximum voltage limits during transient events.
Is the 5KP75A-E3/54 suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the 5KP75A-E3/54 is explicitly AEC-Q101 qualified per the Vishay datasheet (Document Number 88308, Revision 16-Mar-2023). This qualification covers high-temperature operating life, temperature cycling, unbiased highly accelerated stress test, and electrostatic discharge - making it appropriate for engine control units, battery management systems, and ADAS power domains.
What does the "-E3/54" suffix indicate in the 5KP75A-E3/54 part number?
The "-E3" denotes RoHS-compliant, commercial-grade termination meeting JESD 201 Class 1A whisker resistance; "/54" specifies the preferred packaging code for 13-inch paper tape and reel with 800 units per reel. This format aligns with Vishay's standardized ordering nomenclature and ensures compatibility with SMT pick-and-place feeders despite the device being through-hole.
How does the 5KP75A-E3/54 differ from bidirectional TVS diodes in circuit implementation?
The 5KP75A-E3/54 is unidirectional only, meaning it conducts in reverse bias above VBR but blocks forward current beyond ~3.5 V. Unlike bidirectional variants, it cannot protect AC-coupled signals or symmetric rails without external polarity management - but offers lower leakage and tighter VBR tolerance for DC applications like automotive battery lines.
Can the 5KP75A-E3/54 be used in parallel to increase surge current handling?
No - the 5KP75A-E3/54 should not be paralleled due to mismatch in VBR tolerance (83.3–92.1 V) and dynamic impedance, which causes uneven current sharing and potential thermal runaway. For higher current needs, select a higher-rated device (e.g., 5KP85A) or implement staged protection with upstream current-limiting impedance.
