Product details
Overview
1PMT5925A/TR13 from Microsemi is a 10 V, 3.0 W surface-mount Zener diode in the Powermite® package, featuring a full metallic bottom, integral heat sink locking tab, and 30°C/W thermal resistance from junction to TAB 1. It delivers tight ±5% voltage tolerance, low reverse leakage (≤5 µA at 8.0 V), and ESD rating >16 kV HBM for robust protection in power regulation circuits.
For engineers reviewing the 1PMT5925A/TR13 datasheet, 1PMT5925A/TR13 pinout, 1PMT5925A/TR13 application, or 1PMT5925A/TR13 equivalent, key selection criteria include its 10 V nominal Zener voltage at 37.5 mA test current, dynamic impedance of 4.5 Ω, knee impedance of 0.25 Ω, and compatibility with EIA-481 tape-and-reel packaging for automated assembly.
Technical Context
This Zener diode operates as a precision voltage reference and overvoltage clamp in DC power rails, leveraging its stable 10 V breakdown with low dynamic impedance (4.5 Ω) and minimal knee impedance (0.25 Ω) to maintain regulation under varying load currents. Its thermal design centers on TAB 1 as the cathode terminal and primary heat path, with 30°C/W junction-to-tab resistance enabling reliable 3.0 W dissipation when mounted on thermally optimized PCB copper.
The device is rated for -55°C to +150°C junction/storage temperature and exhibits ≤5 µA reverse leakage at VR = 8.0 V. Its forward voltage is 1.2 V at 200 mA, confirming silicon PN-junction construction and suitability for bidirectional transient suppression when used with series blocking elements.
Key Specifications

FAQ
What is the Zener voltage tolerance for 1PMT5925A/TR13?
The 1PMT5925A/TR13 has a standard Zener voltage tolerance of ±5% at 10 V nominal, measured at 37.5 mA test current with TAB 1 held at 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D respectively, but the base part number 1PMT5925A/TR13 specifies ±5%.
How is thermal management implemented in the 1PMT5925A/TR13 package?
The 1PMT5925A/TR13 uses TAB 1 as both cathode and primary thermal conduction path, with a specified junction-to-TAB thermal resistance of 30°C/W. Its full metallic bottom and integral locking tab ensure low-impedance heat transfer to PCB copper, enabling full 3.0 W dissipation when TAB 1 is soldered to an adequately sized thermal pad.
Is the 1PMT5925A/TR13 compatible with lead-free reflow processes?
Yes, the 1PMT5925A/TR13 is qualified for standard lead-free reflow profiles per J-STD-020. Its Powermite® package withstands peak temperatures up to 260°C, and the full metallic bottom prevents flux entrapment-reducing voiding risk and ensuring reliable solder joint integrity during Pb-free assembly.
What is the maximum reverse leakage current for 1PMT5925A/TR13 at 8.0 V?
The maximum reverse leakage current for 1PMT5925A/TR13 is 5 µA at VR = 8.0 V and TL = 30°C. This low leakage supports high-impedance bias networks and minimizes quiescent power loss in battery-powered or energy-sensitive applications.
Does the 1PMT5925A/TR13 have polarity marking, and how is cathode identified?
Yes, the 1PMT5925A/TR13 identifies cathode via TAB 1, which is physically distinct as the metallic tab on one side of the Powermite® package. The molded body side serves as the anode. No additional marking (e.g., band or dot) is used-the tab itself is the definitive polarity indicator per Microsemi mechanical drawings.
