Product details
Overview
P6KE100HE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 100 V standoff voltage (VWM = 85.5 V), 137 V maximum clamping voltage at 4.4 A peak pulse current (10/1000 µs), 600 W peak pulse power rating, and AEC-Q101 qualification - deployed in automotive body control modules to safeguard microcontrollers against load-dump transients.
For engineers reviewing the P6KE100HE3/73 datasheet, P6KE100HE3/73 pinout, P6KE100HE3/73 application, or P6KE100HE3/73 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, thermal resistance (RθJL = 20 °C/W), unidirectional polarity marking, and compliance with automotive surge immunity standards such as ISO 7637-2 Pulse 5a.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal bias it presents <1 µA leakage at 85.5 V; when transient voltage exceeds 95–105 V (VBR min/max at 1 mA), it avalanches into low-impedance conduction within <1 ns, diverting surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surges.
The device is rated for 100 A non-repetitive forward surge current (8.3 ms half-sine), supports soldering up to 275 °C for 10 s, and maintains operation across –55 °C to +175 °C junction temperature range. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - critical for automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 85.5 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets upper limit for protected line's nominal DC voltage. |
| VBR (min/max) | 95.0 V / 105 V at 1 mA - Confirmed avalanche initiation window; ensures reliable turn-on before damage threshold of 12 V MCU I/O or 5 V logic rails. |
| VC @ IPPM | 137 V at 4.4 A (10/1000 µs) - Clamped voltage seen by protected circuit during worst-case surge; must stay below IC's absolute max rating. |
| PPPM | 600 W - Peak pulse power handling capacity; enables suppression of ISO 7637-2 Pulse 5a (load dump) without failure. |
| RθJL | 20 °C/W - Junction-to-lead thermal resistance; allows direct PCB copper pour heatsinking to sustain repeated surges without thermal runaway. |
| TJ max | +175 °C - Maximum junction temperature; supports under-hood placement near engine control units with minimal derating. |
| AEC-Q101 | Qualified - Validated for automotive use per stress test requirements including HTOL, TC, UHAST, and ESD; required for OEM Tier 1 BOMs. |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with matte tin-plated leads. Cathode indicated by color band on one end; anode is unmarked lead.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked lead) | Forward current entry / low-side reference | Connected to ground or low-voltage rail; defines reference point for clamping action during positive transients. |
| Cathode (banded lead) | Reverse-biased terminal / high-side connection | Connected to protected line (e.g., 12 V battery rail); avalanche conduction occurs when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable, repeatable breakdown voltage over 10+ years in humid or thermally cycled environments - critical for automotive field life. |
| 600 W peak pulse power (10/1000 µs) | Handles ISO 7637-2 Pulse 5a load-dump events (up to 60 V superimposed on 14 V system) without degradation or parametric shift. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive under-hood deployment including high-temp storage, thermal shock, and humidity exposure per JEDEC standards. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), reducing risk of latch-up or gate oxide rupture in MOSFETs/ICs. |
| Matte tin plating, J-STD-002 compliant | Guarantees reliable solder wetting and intermetallic formation on PCBs using lead-free reflow profiles - eliminates voiding or dewetting defects. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A | Same VWM (85.5 V) and VC (137 V), but lower PPPM (400 W) and smaller SMA package (RθJA = 110 °C/W vs. 75 °C/W). | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a without parallel staging. | Select SMAJ100A only for space-constrained consumer applications where surge energy is limited to IEC 61000-4-5 Level 3. |
| 1.5KE100A | Identical electrical specs (VWM, VBR, VC, PPPM) but commercial-grade (non-AEC-Q101) and E3-only (no HE3 variant). | Not approved for automotive production; requires additional qualification testing for Tier 1 programs. | Choose 1.5KE100A for industrial or telecom prototypes where AEC-Q101 is not mandated and cost is prioritized. |
Compared with SMAJ100A and 1.5KE100A, P6KE100HE3/73 uniquely delivers AEC-Q101 qualification, DO-15 mechanical robustness for manual assembly, and verified thermal performance in high-temperature automotive environments - making it the only drop-in solution for production BCMs requiring zero requalification.

FAQ
What is the clamping voltage of P6KE100HE3/73 at its rated peak pulse current?
The P6KE100HE3/73 has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 4.4 A under the standard 10/1000 µs waveform. This value is measured at the device terminals and represents the highest voltage that will appear across the protected circuit during a worst-case transient event - a critical parameter for ensuring compatibility with downstream IC voltage tolerances. The P6KE100HE3/73 maintains this clamping performance across its full operating temperature range.
Is P6KE100HE3/73 suitable for automotive applications?
Yes, P6KE100HE3/73 is explicitly qualified to AEC-Q101 standards, confirmed by the HE3 suffix, and rated for operation from –55 °C to +175 °C junction temperature. It is widely used in automotive body control modules, infotainment power supplies, and sensor interface circuits where protection against load-dump and inductive switching transients is required. The P6KE100HE3/73 meets all stress-test requirements including high-temperature operating life, thermal cycling, and unbiased highly accelerated stress testing.
How does the P6KE100HE3/73 differ from the commercial-grade P6KE100A-E3/73?
The P6KE100HE3/73 differs from P6KE100A-E3/73 solely in qualification level: the HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas the E3 suffix indicates RoHS-compliant commercial grade only. Both share identical electrical parameters (VWM, VBR, VC, PPPM) and DO-15 packaging. The P6KE100HE3/73 is required for automotive production; P6KE100A-E3/73 is acceptable for industrial prototyping where automotive qualification is not mandated.
What is the thermal resistance of P6KE100HE3/73, and why does it matter?
The P6KE100HE3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling efficient heat transfer from the silicon die to PCB copper pours or chassis mounts. This low RθJL is essential for sustaining repetitive surge events - such as those in motor drive feedback loops - without exceeding the +175 °C maximum junction temperature. Unlike RθJA, RθJL reflects real-world heatsinking capability when leads are soldered to wide copper traces, making it the most relevant thermal metric for P6KE100HE3/73 layout design.
Can P6KE100HE3/73 be used in bi-directional protection circuits?
No, P6KE100HE3/73 is a uni-directional TVS diode, as indicated by the "A" suffix and presence of cathode band marking. For bi-directional protection (e.g., AC signal lines or RS-485 buses), the corresponding part is P6KE100CA or P6KE100CAHE3/73 - which lacks polarity marking and provides symmetrical clamping in both directions. Using P6KE100HE3/73 in a bi-directional configuration would result in forward conduction and potential failure during negative transients.
