Product details
Overview
P6KE200A-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection of DC power rails and signal lines. It features 190 V to 210 V breakdown voltage (VBR) at 1 mA, 171 V maximum standoff voltage (VWM), 274 V clamping voltage (VC) at 2.2 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the P6KE200A-E3/73 datasheet, P6KE200A-E3/73 pinout, P6KE200A-E3/73 application, or P6KE200A-E3/73 equivalent, key selection criteria include verified clamping performance under 2.2 A surge, thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification status, and DO-15 mechanical compatibility with legacy PCB footprints.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: it remains high-impedance below VWM (171 V), avalanches sharply at VBR (190–210 V), and limits transient energy by clamping to ≤274 V at 2.2 A. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 μA at VWM).
Designed for single-pulse transients (e.g., ISO 7637-2 pulse 1/2a/5a), it delivers 600 W peak power handling with 0.01 % duty cycle, derates linearly above 25 °C ambient, and sustains 100 A non-repetitive forward surge (8.3 ms half-sine) - enabling robust front-end protection without active control circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 190 V / 210 V at 1 mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 171 V - maximum continuous DC or RMS operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 274 V at 2.2 A - clamping voltage limiting downstream component stress during 10/1000 μs surge |
| PPPM | 600 W - peak transient power absorption capability with standardized 10/1000 μs waveform |
| RθJL | 20 °C/W - thermal resistance from junction to lead, critical for sustained power dissipation in leaded packages |
| TJ max. | +175 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| IFSM | 100 A - peak forward surge current rating (8.3 ms half-sine), supporting inrush and load-dump immunity |
Pinout & Package
Package: DO-15 (DO-204AC) - axial-leaded, molded epoxy case with matte tin-plated leads; meets UL 94 V-0 flammability; RoHS compliant (E3 suffix); 0.242–0.258 inch body length, 0.130–0.138 inch diameter.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Cathode | Protected line connection | Marked with color band; connects to DC rail or signal line requiring overvoltage suppression |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance (±5 %), low leakage (<1 μA), and long-term reliability under thermal cycling |
| 600 W peak pulse power (10/1000 μs) | Provides industry-standard surge immunity for automotive load dump (ISO 7637-2 Pulse 5a) and inductive switching events |
| AEC-Q101 qualified (HE3 variant only) | P6KE200A-E3/73 is commercial grade; HE3 suffix required for automotive-grade qualification per AEC-Q101 stress test requirements |

Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: 24 V battery-fed ECU power input subjected to ISO 7637-2 Pulse 5a (load dump up to 60 V for 400 ms). IC Role / Device Role / Timing Role: Unidirectional shunt clamp placed between +24 V rail and chassis ground to limit voltage excursion to ≤274 V. Use Value: Prevents damage to downstream DC-DC converters and microcontrollers by clamping transients within safe operating area defined by VC and IPPM. | Use Scenario: 4–20 mA analog current loop in factory automation exposed to ESD and cable discharge events. IC Role / Device Role / Timing Role: Bidirectional protection not applicable; P6KE200A-E3/73 used unidirectionally across loop supply to suppress positive-going surges only. Use Value: Maintains loop integrity by limiting voltage on supply rail to <274 V while adding <1 μA leakage at 171 V, avoiding measurement drift. |
| Telecom DC Power Feeds | Consumer Appliance Motor Drive Inputs |
Use Scenario: -48 V DC telecom power distribution board encountering lightning-induced surges on long-line feeds. IC Role / Device Role / Timing Role: Unidirectional TVS connected anode-to-ground, cathode-to-line to clamp positive transients on negative supply rail. Use Value: Enables compliance with ITU-T K.20/21 immunity standards by limiting clamped voltage to 274 V at 2.2 A, preserving rectifier and filter capacitor reliability. | Use Scenario: BLDC motor controller input stage exposed to back-EMF spikes during commutation in HVAC blowers. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main DC bus (e.g., 310 V PFC output) to protect gate drivers and MOSFETs. Use Value: Absorbs 600 W surge energy without degradation, sustaining 100 A forward surge to handle repetitive motor switching stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | Surface-mount SMB package; same VBR range (190–210 V), identical PPPM (600 W), but lower IPPM (2.1 A) and higher VC (287 V) | Requires PCB redesign for SMT placement; better suited for space-constrained designs where reflow compatibility is prioritized | Select SMBJ200A when transitioning from through-hole to surface-mount assembly and board real estate is limited. |
| 1.5KE200A | Same DO-15 package and pinout; higher PPPM (1500 W), higher IPPM (5.5 A), and higher VC (328 V); larger junction capacitance | Used where higher surge energy absorption is required (e.g., heavy industrial mains input), but adds more voltage stress during clamping | Choose 1.5KE200A when protecting against higher-energy transients (e.g., AC line surges) and system design tolerates 328 V clamping. |
Compared with SMBJ200A and 1.5KE200A, P6KE200A-E3/73 offers optimal balance of proven DO-15 mechanical reliability, 274 V clamping headroom, and cost-effective through-hole manufacturability - making it preferred for legacy automotive and industrial control boards where footprint compatibility and thermal derating predictability are critical.

FAQ
What is the breakdown voltage range of the P6KE200A-E3/73?
The P6KE200A-E3/73 has a guaranteed breakdown voltage (VBR) range of 190 V to 210 V at 1 mA test current, measured per ANSI/IEEE C62.35. This tight ±5 % tolerance ensures consistent avalanche initiation across production lots and supports precise overvoltage threshold design in 24 V and 48 V systems where P6KE200A-E3/73 is commonly applied.
Is the P6KE200A-E3/73 AEC-Q101 qualified?
No, the P6KE200A-E3/73 is the commercial-grade variant (E3 suffix). For AEC-Q101 qualification, the part must carry the HE3 suffix (e.g., P6KE200AHE3/73), which undergoes additional stress testing including HTOL, temperature cycling, and ESD per AEC-Q101 Rev D. The P6KE200A-E3/73 remains suitable for non-automotive industrial and telecom applications where full automotive qualification is not mandated.
What is the maximum clamping voltage of the P6KE200A-E3/73 under surge conditions?
The P6KE200A-E3/73 clamps to a maximum of 274 V at its rated peak pulse current of 2.2 A, tested with the standard 10/1000 μs waveform. This VC value is critical for determining the safe operating margin of downstream components - for example, ensuring that a 300 V-rated electrolytic capacitor remains within its voltage limit during transient events where P6KE200A-E3/73 is deployed.
Can the P6KE200A-E3/73 be used in bidirectional configurations?
No, the P6KE200A-E3/73 is a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional operation requires the CA-suffixed variant (e.g., P6KE200CA). Using P6KE200A-E3/73 in reverse-biased configurations will result in forward conduction and failure; it must be oriented with cathode toward the protected line and anode to ground to function correctly as specified in the P6KE200A-E3/73 datasheet.
What is the thermal resistance of the P6KE200A-E3/73, and why does it matter?
The P6KE200A-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, measured under standard lead-length conditions. This parameter directly impacts power derating: at elevated ambient temperatures or repeated surges, heat buildup at the junction must be conducted efficiently through the leads to avoid exceeding the 175 °C maximum junction temperature - a key reliability factor in enclosed automotive or industrial enclosures where P6KE200A-E3/73 is often installed.
