Product details
Overview
1PMT5936CE3/TR13 from Microsemi is a 30 V, ±5% tolerance Zener diode in Powermite® surface-mount package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with 12.5 mA test current (IZT), 28 Ω dynamic impedance (ZZT), and 1 µA max reverse leakage at 22.8 V. It serves as a precision voltage reference or overvoltage clamp in DC power rails of industrial power supplies.
For engineers reviewing the 1PMT5936CE3/TR13 datasheet, 1PMT5936CE3/TR13 pinout, 1PMT5936CE3/TR13 application, or 1PMT5936CE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (30°C/W junction-to-TAB), ESD rating (>16 kV HBM), low knee impedance, 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 Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and eliminate solder flux entrapment during reflow.
Electrical behavior is defined at TL = 30°C with Zener voltage measured 20 seconds after DC current application. Dynamic impedance is derived using 60 Hz RMS AC current equal to 10% of IZT, and maximum power dissipation accounts for voltage rise at elevated temperature and current.
Key Specifications

FAQ
What is the Zener voltage tolerance for 1PMT5936CE3/TR13?
The 1PMT5936CE3/TR13 has a standard Zener voltage tolerance of ±5% at 30 V, measured at 12.5 mA test current with TAB 1 held at 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, but the CE3 designation confirms the ±5% version. This tolerance ensures predictable clamping behavior in industrial power rails where ±1.5 V deviation is acceptable.
How is thermal management handled in the 1PMT5936CE3/TR13 package?
The 1PMT5936CE3/TR13 uses a Powermite® package with a full metallic bottom and integral locking tab that acts as an efficient heat sink. Its specified thermal resistance is 30°C/W junction-to-TAB, meaning TAB 1 must be soldered to a thermally robust PCB copper area. This design allows the 1PMT5936CE3/TR13 to safely dissipate its full 3.0 W rating without external heatsinking under typical board conditions.
Is the 1PMT5936CE3/TR13 compatible with automated SMT assembly?
Yes, the 1PMT5936CE3/TR13 is fully compatible with automated insertion equipment and standard SMT processes. It is supplied in EIA-481-compliant tape-and-reel format (TR13 indicates 13-inch reel with 12,000 units), and its Powermite® package geometry and locking tab ensure stable placement and reliable reflow soldering without flux entrapment.
What is the maximum reverse leakage current for 1PMT5936CE3/TR13?
The 1PMT5936CE3/TR13 has a maximum reverse leakage current (IR) of 1 µA at 22.8 V, measured at TL = 30°C. This low leakage supports energy-efficient operation in standby modes and prevents unintended loading of sensitive reference nodes. The value is verified per Microsemi's test conditions and remains stable across the -55°C to +150°C operating junction temperature range.
Does the 1PMT5936CE3/TR13 meet any ESD immunity standards?
Yes, the 1PMT5936CE3/TR13 is rated for >16 kV electrostatic discharge per the Human Body Model (HBM), as confirmed in the MSC0995 datasheet. This high ESD rating ensures robust handling during automated manufacturing, PCB assembly, and field deployment-particularly valuable in automotive and industrial environments where static discharge events are common.
