Color: As the picture shows Quantity: 4 pieces. Features: 1. High reliability. 2. Excellent anti-surge capability. 3. Large PN junction area, low forward voltage drop (Vf). 4. Junction temperature: -40 ~ + prefix = st1ns = "urn: schemas-microsoftcom: office: smarttags" 150 degree Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. The allowed measurement error is +/- 1-3 cm. We greatly appreciate all custom rsopions to improve the sale. If you are not satisfied, please contact us to find the best solution. Thank you! Package includes: 4 Pack 20000V 20KV 2A PRHVP 2A-20 18x19x75mm High Voltage Diode (If the number of products received is incorrect, please contact us. We will refund or offer you a replacement.) Review: So far so good - Physical appearance and initial testing of these PRHVP2A-20 rectifiers at low voltages look good. The provided electrical connection terminals are tabs that accept commonly available 1/4 inch quick-connect receptacles. At around 70 F. room temperature, these start to conduct at forward bias of close to 12.1 volts. The forward voltage drop tops out at around 14.5 volts, a figure typical of high voltage rectifiers such as these. As another reviewer stated, the diode test function of a typical multimeter is not able to check these; due to the forward voltage being considerably higher than that of a single solid state diode junction. I don't have the equipment set up at this time to perform a full reverse voltage test on these. Review: Must test using a battery! Use 9VDC battery with voltmeter. - Due to HV capability, the Diode will not work at low voltages. A multimeter's standard diode test will fail! use a 9 VDC battery and read the voltage drop. ## Features - Features: high reliability, excellent anti-surge ability. - Areas of application: microwave ovens, electromagnetic heating equipment, electrostatic dust removal, electrostatic flocking, lasers, medicines, computer cathode ray monitors, etc. - HVP-12:14:15:16:20, etc. It has high voltage resistance and high current characteristics, and is widely used in high-frequency machines and other wide current rectifier power circuits. - Package Included:4 x 20000V 20KV 2A PRHVP 2A-20 18x19x75mm High Voltage Diode (If the number of products received is incorrect, please contact us.
