Product details
Overview
1PMT5928A/TR13 from Microsemi is a 13 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 7.0 Ω dynamic impedance at 28.8 mA test current and thermal resistance of 30°C/W junction-to-TAB1. It serves as a precision voltage reference or overvoltage clamp in power supply regulation and ESD protection circuits.
For engineers reviewing the 1PMT5928A/TR13 datasheet, 1PMT5928A/TR13 pinout, 1PMT5928A/TR13 application, or 1PMT5928A/TR13 equivalent, key selection criteria include zener voltage accuracy (±5%), low dynamic impedance (7.0 Ω), high ESD rating (>16 kV HBM), thermal performance (30°C/W), and compatibility with automated SMT assembly per EIA-481 tape-and-reel packaging.
Technical Context
This device operates as a two-terminal voltage-regulating diode with cathode designated by TAB 1. Its Zener breakdown is specified at 13 V nominal with 28.8 mA test current (IZT), and it maintains stable regulation across -55°C to +150°C junction temperature range.
The Powermite® package integrates a full metallic bottom and locking tab that functions as an integral heat sink, enabling 3.0 W power handling while eliminating solder flux entrapment. Thermal resistance from junction to TAB 1 is 30°C/W, supporting reliable operation under sustained DC load conditions.
Key Specifications

FAQ
What is the Zener voltage tolerance for 1PMT5928A/TR13?
The 1PMT5928A/TR13 has a standard Zener voltage tolerance of ±5% at 13 V nominal, measured at 28.8 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 1PMT5928A/TR13 part uses the ±5% grade per Microsemi MSC0995 Rev F specification.
How is thermal management implemented in the 1PMT5928A/TR13 package?
The 1PMT5928A/TR13 uses Microsemi's Powermite® package with TAB 1 serving as both cathode and primary thermal path. Its 30°C/W junction-to-TAB1 thermal resistance relies on direct conduction through the full metallic bottom into the PCB copper pad. The locking tab enhances mechanical retention and adds surface area for convective cooling, enabling 3.0 W dissipation at TAB 1 = 60°C.
Is the 1PMT5928A/TR13 suitable for automated SMT assembly?
Yes, the 1PMT5928A/TR13 is fully compatible with automated insertion and reflow processes. Its Powermite® package features coplanar leads and a symmetric footprint aligned with EIA-481 tape-and-reel standards (13-inch reel contains 12,000 units). The full metallic bottom eliminates solder flux entrapment, ensuring consistent solder joint quality in high-volume manufacturing.
What is the maximum reverse leakage current for 1PMT5928A/TR13?
The 1PMT5928A/TR13 specifies a maximum reverse leakage current (IR) of 1 µA at VR = 10.4 V, per the Electrical Characteristics table in MSC0995 Rev F. This low leakage ensures minimal power loss in standby regulation circuits and preserves accuracy in high-impedance reference applications.
Does the 1PMT5928A/TR13 meet any industry-standard ESD ratings?
Yes, the 1PMT5928A/TR13 is rated for >16 kV per the Human Body Model (HBM) ESD test, as stated in the FEATURES section of MSC0995 Rev F. This level exceeds IEC 61000-4-2 Level 4 (8 kV contact), making it suitable for use in systems requiring robust handling immunity without additional ESD protection components.
