Product details
Overview
5KP150A-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 150 V stand-off voltage (VWM), 167–185 V breakdown voltage (VBR) at 5 mA, 243 V clamping voltage (VC) at 20.6 A peak pulse current (IPPM), and 5000 W peak pulse power (10/1000 μs waveform), suitable for automotive and industrial power supply output protection.
For engineers reviewing the 5KP150A-E3/54 datasheet, 5KP150A-E3/54 pinout, 5KP150A-E3/54 application, or 5KP150A-E3/54 equivalent, key selection criteria include clamping voltage margin vs. protected IC's absolute maximum rating, unidirectional polarity compatibility with DC-biased lines, thermal derating above 25 °C, and AEC-Q101 qualification for automotive under-hood use.
Technical Context
This TVS diode operates as a voltage-clamped crowbar alternative: it remains high-impedance below VWM (150 V), breaks down sharply within ±5 % tolerance at VBR (167–185 V), and limits transient voltage to ≤243 V during 10/1000 μs surges up to 20.6 A. Its P600 glass-passivated junction enables low incremental surge resistance and sub-nanosecond response time.
Thermal performance is defined by 8.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C and 175 °C max junction temperature. Derating follows a linear curve above 25 °C ambient, with full power available only at TA ≤ 25 °C per Fig. 2 and Fig. 5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 150 V - Maximum continuous reverse operating voltage before conduction begins; sets upper limit for normal circuit operation. |
| VBR (min/max) | 167 V / 185 V at 5 mA - Confirmed breakdown range ensures reliable triggering without premature conduction. |
| VC @ IPPM | 243 V at 20.6 A - Clamping voltage during 10/1000 μs surge; must be below protected device's absolute max rating. |
| PPPM | 5000 W - Peak pulse power handling capability defines survivability against lightning or inductive switch-off transients. |
| TJ max. | +175 °C - Maximum junction temperature supports under-hood automotive deployment with validated thermal design. |
| Polarity | Unidirectional - Requires cathode band oriented toward positive rail; not suitable for AC or bidirectional signal lines. |
| AEC-Q101 | Qualified - Validated for automotive applications including engine control units and body electronics per stress test requirements. |
Pinout & Package
Package: P600 molded epoxy case with glass-passivated chip junction, UL 94 V-0 rated, matte tin-plated leads solderable per J-STD-002. Cathode indicated by color band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or negative rail; carries full surge current during clamping event. |
| Cathode | High-side connection point | Marked by color band; connected to protected line (e.g., +12 V rail); defines unidirectional conduction path. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Enables single-device protection against IEC 61000-4-5 Level 4 (4 kV/2 Ω) surges on 12 V/24 V systems. |
| AEC-Q101 qualification | Validates reliability for automotive powertrain and chassis modules without additional qualification testing. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on downstream MOSFETs or controllers during transient events. |
| P600 package thermal mass | Supports 8.0 W steady-state dissipation at TL = 75 °C, enabling direct PCB mounting without dedicated heatsink in moderate-power designs. |
| Fast response time (< 1 ns) | Clamps transients before sensitive ICs experience latch-up or gate oxide damage. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A | Lower PPPM (600 W), smaller SMB package, same VWM (150 V), higher VC (243 V at 2.5 A) | Not suitable for IEC 61000-4-5 Level 4; limited to low-energy signal-line or secondary-side protection. | Select SMBJ150A only when surge energy is <100 mJ and board space is constrained. |
| 1.5KE150A | Same VWM (150 V), lower PPPM (1500 W), DO-201 package, higher VF (3.5 V), no AEC-Q101 qualification | Lacks automotive qualification and thermal robustness for under-hood use; requires larger PCB footprint than P600. | Choose 1.5KE150A for cost-sensitive industrial controls where AEC-Q101 is not required. |
Compared with SMBJ150A and 1.5KE150A, the 5KP150A-E3/54 delivers 3.3× higher peak pulse power and AEC-Q101 validation-making it the sole option among the three qualified for automotive power rail protection with full IEC 61000-4-5 Level 4 compliance.

FAQ
What is the clamping voltage of the 5KP150A-E3/54 under a standard 10/1000 μs surge?
The 5KP150A-E3/54 clamps to a maximum of 243 V when subjected to its rated peak pulse current of 20.6 A using the 10/1000 μs waveform. This value is guaranteed per JEDEC test conditions and appears in the Electrical Characteristics table on page 2 of Vishay document 88308. The 5KP150A-E3/54 maintains this clamping performance across its qualified temperature range.
Is the 5KP150A-E3/54 suitable for bidirectional signal line protection?
No-the 5KP150A-E3/54 is unidirectional only, as confirmed in the FEATURES section of the datasheet. It conducts only when reverse-biased beyond VBR and cannot suppress positive-going transients on AC or differential signal lines. For bidirectional protection, a pair of 5KP150A-E3/54 devices in series-opposing configuration or a dedicated bidirectional TVS like 5KP150CA would be required.
Does the 5KP150A-E3/54 meet automotive qualification standards?
Yes-the 5KP150A-E3/54 is explicitly AEC-Q101 qualified, as noted in the MECHANICAL DATA section and footnote (1) on page 3 of the Vishay datasheet. This qualification covers stress tests including HTGB, HTRB, TCT, and ESD, validating its use in automotive powertrain, body, and infotainment modules.
What is the maximum steady-state power dissipation for the 5KP150A-E3/54?
The 5KP150A-E3/54 has a maximum steady-state power dissipation (PD) of 8.0 W when mounted on an infinite heatsink at lead temperature (TL) of 75 °C, per the MAXIMUM RATINGS table. At ambient temperatures above 25 °C, power must be linearly derated per Figure 5, reaching zero at TJ = 175 °C.
How is polarity identified on the 5KP150A-E3/54 package?
Polarity is marked by a color band on the cathode end of the P600 package, consistent with industry-standard diode marking. The cathode terminal connects to the protected positive rail, while the anode connects to ground or the negative reference. This unidirectional orientation is critical for correct circuit integration and must align with schematic symbol placement.
