Product details
Overview
P6KE47CA-E3/73 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 47 V breakdown voltage (VBR min/max = 44.7–49.4 V at 1.0 mA), 40.2 V standoff voltage (VWM), 64.8 V maximum clamping voltage (VC) at 9.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial systems.
For engineers reviewing the P6KE47CA-E3/73 datasheet, P6KE47CA-E3/73 pinout, P6KE47CA-E3/73 application, or P6KE47CA-E3/73 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, thermal resistance (RθJA = 75 °C/W), AEC-Q101 qualification status, and compliance with UL 497B surge protector classification.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while fast response time (<1.0 ns) limits transient energy delivered to downstream components.
The device sustains repetitive 10/1000 µs surges at 0.01% duty cycle and derates linearly above 25 °C ambient, with maximum junction temperature of +175 °C and thermal resistance from junction to lead of 20 °C/W - supporting reliable operation in high-temperature PCB environments when mounted with adequate copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 44.7 V / 49.4 V at 1.0 mA - defines guaranteed conduction onset range under standardized test conditions |
| VWM | 40.2 V - maximum continuous reverse working voltage before significant leakage begins |
| VC @ IPPM | 64.8 V at 9.3 A - clamped voltage during 600 W transient, limiting stress on protected circuitry |
| PPPM | 600 W - peak pulse power handling with 10/1000 µs waveform, defining surge robustness level |
| IPPM | 9.3 A - peak pulse current corresponding to VC, used to size upstream fusing or current-limiting elements |
| TJ max. | +175 °C - maximum junction temperature, enabling use in under-hood automotive or industrial enclosures |

FAQ
What is the breakdown voltage tolerance for P6KE47CA-E3/73?
The P6KE47CA-E3/73 has a minimum breakdown voltage (VBR) of 44.7 V and a maximum of 49.4 V at 1.0 mA test current, yielding a ±4.7% tolerance band around the nominal 47 V rating. This tight distribution ensures consistent clamping behavior across production lots and supports predictable system-level surge margin calculations without derating overhead.
Is P6KE47CA-E3/73 RoHS compliant and halogen-free?
Yes, P6KE47CA-E3/73 carries the "E3" suffix indicating full RoHS compliance per EU Directive 2011/65/EU and meets Vishay's material categorization standard for halogen-free content (chlorine <900 ppm, bromine <900 ppm). The molding compound also satisfies UL 94 V-0 flammability requirements, confirming suitability for safety-critical end equipment.
Does P6KE47CA-E3/73 require heatsinking for 600 W pulse handling?
No - the 600 W peak pulse power rating applies to single-event 10/1000 µs transients, not continuous dissipation. P6KE47CA-E3/73 relies on thermal mass of its leads and PCB copper for transient energy absorption. For repetitive surges, derating per Figure 2 in the datasheet is required; sustained power dissipation remains limited to 5.0 W at TL = 75 °C with infinite heatsink.
How does the bidirectional nature of P6KE47CA-E3/73 affect PCB layout?
The bidirectional construction of P6KE47CA-E3/73 eliminates polarity constraints: either lead may connect to signal or ground, simplifying layout and eliminating risk of reverse installation. This symmetry supports placement across AC-coupled lines, differential pairs, or ungrounded rails - unlike unidirectional variants that require strict cathode-to-ground orientation.
What is the maximum allowable solder temperature for P6KE47CA-E3/73?
P6KE47CA-E3/73 supports solder dip at 275 °C maximum for 10 seconds per JESD 22-B106, and its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 for wetting and adhesion. Reflow profiles must stay within peak temperature limits specified for DO-15 packages (typically ≤260 °C for 10 s) to avoid internal delamination or bond wire damage.
