Product details
Overview
5KP20-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 5000 W peak pulse power (10/1000 μs), 20 V stand-off voltage (VWM), 32.4 V maximum clamping voltage (VC) at 154 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the 5KP20-E3/54 datasheet, 5KP20-E3/54 pinout, 5KP20-E3/54 application, or 5KP20-E3/54 equivalent, this device is selected for robust overvoltage protection in switching power supply outputs, automotive ECU power inputs, and industrial sensor interface circuits where fast response (<1 ns), low clamping ratio, and high IPPM capability are critical.
Technical Context
The 5KP20-E3/54 uses a glass-passivated P600 chip junction with uni-directional polarity, enabling it to clamp positive transients only while blocking reverse leakage below 2.0 μA at 20 V. Its 175 °C maximum junction temperature and 8.0 W steady-state power dissipation support operation in thermally constrained environments with adequate heatsinking.
It delivers 5000 W peak pulse power under JEDEC-standard 10/1000 μs waveform with 0.01% duty cycle, and exhibits 0.099 %/°C temperature coefficient of breakdown voltage - ensuring stable clamping performance across automotive temperature ranges (-55 °C to +175 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 20 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 24 V systems. |
| VBR @ IT | 22.2–24.5 V @ 5.0 mA - Breakdown voltage range ensures reliable turn-on during overvoltage events without premature conduction. |
| VC @ IPPM | 32.4 V @ 154 A - Clamping voltage limits downstream IC stress during 5 kA-level surges; clamping ratio = 1.62×VWM. |
| PPPM | 5000 W - Peak pulse power rating enables suppression of severe lightning-induced or inductive-switching transients per ISO 7637-2 Pulse 5a. |
| IPPM | 154 A - Peak pulse current capacity supports >100 A surge handling on 12–24 V power buses without degradation. |
| TJ max. | 175 °C - High junction temperature rating allows use in under-hood automotive locations and industrial enclosures without derating. |
| Polarity | Uni-directional - Cathode-banded configuration protects against positive-going transients only; requires correct orientation in series with load. |
Pinout & Package
5KP20-E3/54 is housed in a P600 molded epoxy package (JEDEC DO-201AD), with axial leads and cathode band marking. The device has two terminals: anode and cathode - no internal circuitry or additional pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to ground or low-side return path; must be routed with low-inductance trace for effective surge shunting. |
| Cathode | Current exit terminal during clamping; marked by color band | Connected to protected line (e.g., 24 V rail); polarity reversal prevents clamping and risks catastrophic failure. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Enables single-device protection against ISO 7637-2 Pulse 5a (500 V/12 Ω, tr=10 μs) on 24 V systems without parallel staging. |
| AEC-Q101 qualified (HE3 suffix variant confirmed; E3 meets commercial spec with identical electricals) | Validated for automotive powertrain and body electronics applications requiring zero-failure reliability under thermal cycling and humidity exposure. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ESD or relay bounce), reducing risk of latch-up in downstream MOSFET drivers. |
| UL 94 V-0 compliant molding compound | Ensures flame-retardant housing integrity during sustained overcurrent fault conditions, meeting IPC-CC-830B and automotive safety standards. |
| Matte tin-plated leads, J-STD-002 solderable | Supports lead-free reflow and wave soldering processes without dewetting or voiding; compatible with standard PCB assembly lines. |
Applications
| Automotive Power Input Protection | Industrial PLC Digital I/O Protection |
|---|---|
Use Scenario: Protecting 24 V power input of engine control units (ECUs) against load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Primary clamping element placed between battery rail and DC/DC converter input, absorbing >5000 W surges within nanoseconds. Use Value: Prevents permanent damage to upstream fuse boxes and downstream regulators by limiting transient voltage to ≤32.4 V during 154 A pulses. |
Use Scenario: Shielding 24 V digital input channels of programmable logic controllers from field-wiring induced transients (e.g., valve coil switching). IC Role / Device Role / Timing Role: Standoff protector mounted at connector entry point, shunting surge energy to chassis ground before reaching optocoupler input stage. Use Value: Maintains signal integrity and extends optocoupler lifetime by suppressing >1 kV transients with <1 ns response and sub-μA leakage at 20 V. |
| Switching Power Supply Output Clamp | Sensor Signal Line Surge Suppression |
Use Scenario: Replacing crowbar circuits on secondary-side outputs of 24 V/5 A SMPS used in factory automation equipment. IC Role / Device Role / Timing Role: Fast-acting voltage clamp that conducts only during overvoltage, allowing fuse interruption instead of short-circuit shutdown. Use Value: Enables system reset after fault clearance (vs. crowbar destruction), reducing maintenance downtime and component replacement cost. |
Use Scenario: Protecting analog output lines (0–10 V / 4–20 mA) of pressure/temperature sensors in harsh industrial environments. IC Role / Device Role / Timing Role: Low-capacitance (typ. <100 pF) uni-directional TVS placed inline with signal conductor, referenced to local ground. Use Value: Preserves signal bandwidth and accuracy while clamping EFT bursts (IEC 61000-4-4) up to ±2 kV without loading the sensor output impedance. |
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 SMAJ20A | Lower peak power (400 W), smaller SMA package (3.5 × 4.5 mm), 34.0 V VC @ 11.8 A | Targeted at board-level signal-line protection, not primary power rail clamping | Select when space-constrained layouts require surface-mount devices and surge energy is ≤400 W. |
| ON Semiconductor 1.5KE20A | Same P600 package, lower peak power (1500 W), 35.5 V VC @ 42.3 A, non-AEC-Q101 | Cost-optimized for commercial industrial power supplies without automotive qualification | Choose for non-automotive 24 V systems where 1.5 kW surge immunity suffices and AEC-Q101 is not mandated. |
Compared with SMAJ20A and 1.5KE20A, the 5KP20-E3/54 delivers 3.3× higher peak power than 1.5KE20A and 12.5× more than SMAJ20A - making it uniquely suitable for primary-side protection in high-reliability 24 V automotive and industrial power distribution networks.

FAQ
What is the maximum clamping voltage of the 5KP20-E3/54 under rated surge conditions?
The 5KP20-E3/54 has a maximum clamping voltage (VC) of 32.4 V at 154 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed per JEDEC test conditions and ensures downstream components see no more than 32.4 V during worst-case transient events. The 5KP20-E3/54 maintains this clamping performance across its full operating temperature range.
Is the 5KP20-E3/54 suitable for automotive applications requiring AEC-Q101 qualification?
The 5KP20-E3/54 carries the E3 suffix, indicating RoHS-compliant commercial grade construction. While the HE3 variant (e.g., 5KP20HE3/54) is explicitly AEC-Q101 qualified, the 5KP20-E3/54 shares identical electrical characteristics and P600 package construction. For non-safety-critical automotive subsystems, the 5KP20-E3/54 is widely deployed - but AEC-Q101 certification applies strictly to HE3-suffixed parts per Vishay documentation.
How does the 5KP20-E3/54 compare to the 1.5KE20A in terms of surge handling capability?
The 5KP20-E3/54 provides 5000 W peak pulse power versus 1500 W for the 1.5KE20A - a 3.3× higher energy absorption capacity. Its 154 A IPPM exceeds the 1.5KE20A's 42.3 A, and its 32.4 V VC is lower than the 1.5KE20A's 35.5 V. These differences make the 5KP20-E3/54 appropriate for demanding load-dump and lightning-surge scenarios where the 1.5KE20A would fail or degrade.
What is the reverse leakage current specification for the 5KP20-E3/54 at its stand-off voltage?
At VWM = 20 V and TA = 25 °C, the 5KP20-E3/54 exhibits a maximum reverse leakage current (ID) of 2.0 μA. This ultra-low leakage ensures minimal power loss in standby mode and avoids false triggering in precision 24 V monitoring circuits - a key advantage over higher-leakage alternatives like Zener-based protectors.
Can the 5KP20-E3/54 be used in surface-mount designs?
No - the 5KP20-E3/54 is an axial-lead P600 package device intended for through-hole mounting only. Its 9.5 mm body length and 0.375" lead spacing are incompatible with SMT reflow profiles and pick-and-place equipment. For surface-mount equivalents, consider the SMAJ20A or SMCJ20A families, though these offer significantly lower peak power ratings than the 5KP20-E3/54.
