Product details
Overview
1PMT5932E3/TR13 from Microsemi is a 20 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 14 Ω dynamic impedance at 18.7 mA test current and thermal resistance of 30°C/W junction-to-tab - used for precision voltage regulation and overvoltage protection in compact DC power rails.
For engineers reviewing the 1PMT5932E3/TR13 datasheet, 1PMT5932E3/TR13 pinout, 1PMT5932E3/TR13 application, or 1PMT5932E3/TR13 equivalent, key selection criteria include zener voltage tolerance, power derating above 60°C, knee current (0.25 mA), reverse leakage (<1 µA at 15.2 V), and ESD robustness (>16 kV HBM).
Technical Context
This Zener diode operates as a two-terminal voltage reference device with cathode designated by TAB 1, requiring no external biasing. Its full metallic bottom and integral heat sink locking tab enable direct thermal conduction to PCB copper, supporting stable regulation under pulsed or continuous 3.0 W dissipation when mounted on ≥1 sq-in. 2-oz copper.
The device exhibits low reverse leakage (≤1 µA at VR = 15.2 V), tight dynamic impedance (14 Ω at IZT = 18.7 mA), and specified knee behavior (IZK = 0.25 mA, ZZK = 650 Ω), enabling reliable clamping in low-current standby modes and stable regulation across load transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 20 V ±5% at IZT = 18.7 mA, TL = 30°C - defines nominal regulation point with predictable deviation under production tolerance. |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - maximum steady-state power before thermal runaway; derates linearly to zero at 150°C junction. |
| Dynamic Impedance | 14 Ω at 18.7 mA - determines output voltage variation under load current changes; critical for ripple rejection. |
| Knee Current | 0.25 mA - minimum current needed to enter regulated region; enables low-power standby clamping. |
| Thermal Resistance | 30°C/W junction-to-TAB 1 - quantifies temperature rise per watt; requires adequate PCB copper area for thermal management. |
| ESD Rating | >16 kV per HBM - supports handling without additional protection in assembly and field service environments. |
| Reverse Leakage | ≤1 µA at VR = 15.2 V - ensures minimal quiescent current in high-impedance bias networks. |
Pinout & Package
Package: Powermite® surface-mount molded package with full metallic bottom and integral heat sink locking tab; DO-216 outline; cathode identified by TAB 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat path and electrical cathode connection; must be soldered to ≥1 sq-in. 2-oz copper for rated 3.0 W operation. |
| Lead 2 | Anode | Standard anode terminal; electrically isolated from TAB 1; connects to system ground or return path. |
Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the maximum continuous power dissipation for 1PMT5932E3/TR13?
The 1PMT5932E3/TR13 is rated for 3.0 W DC power dissipation at TAB 1 temperature of 60°C. Power must be linearly derated above 60°C, reaching zero at 150°C junction temperature. Derating curves are provided in Microsemi Application Note AN-202, and actual dissipation depends on PCB copper area and airflow.
How is cathode identification implemented on 1PMT5932E3/TR13?
The cathode of the 1PMT5932E3/TR13 is designated by TAB 1, which is the larger metallic pad on the package underside. This tab serves both as the cathode electrical connection and the primary thermal path to the PCB. The anode is connected to lead 2, and polarity must be observed during placement to ensure proper regulation.
Does 1PMT5932E3/TR13 support automated assembly processes?
Yes, the 1PMT5932E3/TR13 is fully compatible with automated insertion and reflow soldering. Its Powermite® package features a unique locking tab that anchors the device during reflow, and its full metallic bottom prevents solder flux entrapment - both features validated for use with standard SMT pick-and-place and convection reflow profiles per J-STD-020.
What is the reverse leakage specification for 1PMT5932E3/TR13 at 15.2 V?
Per the MSC0995 datasheet, the 1PMT5932E3/TR13 exhibits a maximum reverse leakage current of 1 µA at VR = 15.2 V and TL = 30°C. This low leakage supports high-impedance bias networks and minimizes standby power loss in battery-operated systems where the 1PMT5932E3/TR13 is used as a reference or clamp.
Is 1PMT5932E3/TR13 RoHS compliant and halogen-free?
Yes, the 1PMT5932E3/TR13 is RoHS compliant and halogen-free per Microsemi's product change notice PCN-17-002. It meets JEDEC JS-709C and IPC-1752A requirements, with full material declarations available upon request through Aetrix Electronics' compliance portal for 1PMT5932E3/TR13.
