Product details
Overview
1PMT5925BE3/TR13 from Microsemi is a 10 V, ±5% tolerance surface-mount Zener diode in the Powermite® package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with 4.5 mA test current (IZT), 45 Ω dynamic impedance (ZZT), and <5 µA reverse leakage at 8.0 V (VR). It serves as a precision voltage reference or overvoltage clamp in DC power rails of industrial control modules.
For engineers reviewing the 1PMT5925BE3/TR13 datasheet, 1PMT5925BE3/TR13 pinout, 1PMT5925BE3/TR13 application, or 1PMT5925BE3/TR13 equivalent, key selection criteria include its 3.0 W thermal capability via metallic tab, DO-216 mechanical outline, ESD rating >16 kV HBM, and tight zener voltage stability under 37.5 mA max zener current (IZM).
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage regulation across varying load currents. Its Powermite® package integrates a full metallic bottom and locking tab that directly conducts heat from the junction to PCB copper, achieving 30°C/W thermal resistance from junction to TAB 1.
The device exhibits low knee impedance (ZZK = 500 Ω at IZK = 0.25 mA) and tightly controlled dynamic impedance (ZZT = 45 Ω at IZT = 4.5 mA), enabling reliable regulation even near minimum operating current. Reverse leakage remains ≤5 µA up to VR = 8.0 V, supporting low-power standby circuit integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |

FAQ
What is the maximum continuous power dissipation for 1PMT5925BE3/TR13?
The 1PMT5925BE3/TR13 is rated for 3.0 W DC power dissipation when TAB 1 is maintained at 60°C. This rating assumes proper thermal coupling to a PCB copper area per Microsemi's recommended mounting pad dimensions. Exceeding this condition risks junction overheating and parametric shift. Derating is required above 60°C tab temperature per the 30°C/W thermal resistance specification.
How is cathode identification implemented on 1PMT5925BE3/TR13?
The cathode of the 1PMT5925BE3/TR13 is designated by TAB 1-the larger metallic surface on the package bottom. This tab serves both as the cathode electrical connection and the primary thermal path. The anode is the smaller lead (Lead 2) extending from the opposite side. Polarity must be verified during placement using the DO-216 mechanical drawing in MSC0995.PDF.
Does 1PMT5925BE3/TR13 support automated optical inspection (AOI) after reflow?
Yes, the 1PMT5925BE3/TR13 supports AOI due to its consistent DO-216 mold profile and high-contrast metallic tab. The full metallic bottom provides strong reflectivity contrast against solder paste, enabling reliable solder joint inspection. Its EIA-481 tape-and-reel packaging also ensures precise feeder alignment for vision-guided placement verification.
What is the reverse leakage current specification for 1PMT5925BE3/TR13 at 8.0 V?
The reverse leakage current (IR) for 1PMT5925BE3/TR13 is guaranteed ≤5 µA at VR = 8.0 V and TL = 30°C. This value is measured with the device held at constant temperature and confirms low standby power consumption-critical for battery-operated systems where quiescent current must remain below 10 µA across temperature and voltage extremes.
Can 1PMT5925BE3/TR13 be used as a replacement for 1N5925B in existing designs?
No direct replacement: while 1PMT5925BE3/TR13 matches the 1N5925B's 10 V zener voltage and 3.0 W rating, it uses a surface-mount Powermite® (DO-216) package versus the through-hole DO-41. PCB layout, thermal design, and assembly process must be revised. The 1PMT5925BE3/TR13 offers superior thermal performance (30°C/W vs. 50°C/W) but requires SMT reflow compatibility assessment.
