Product details
Overview
1PMT5932BE3/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 1PMT5932BE3/TR13 datasheet, 1PMT5932BE3/TR13 pinout, 1PMT5932BE3/TR13 application, or 1PMT5932BE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, power derating above 60°C, reverse leakage at 15.2 V, knee current behavior at 0.25 mA, and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This Zener diode operates as a two-terminal voltage reference device, with cathode designated by TAB 1 and anode connected to the molded body. Its full metallic bottom ensures flux-free soldering, while integral locking tabs provide mechanical retention and thermal conduction to the PCB pad.
The device delivers stable 20 V regulation under 18.7 mA test current (IZT), exhibits 14 Ω dynamic impedance (ZZT), and maintains ≤1 µA reverse leakage (IR) at VR = 15.2 V - enabling use in low-power sensing, feedback loops, and clamp circuits where thermal stability and low noise are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 20 V ±5% at IZT = 18.7 mA, TL = 30°C - defines nominal regulation point with tight production control |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous DC power handling before thermal derating |
| Dynamic Impedance | 14 Ω at IZT - determines output voltage variation under load current changes |
| Knee Current (IZK) | 0.25 mA - minimum current needed to enter regulated region with <10% deviation |
| Reverse Leakage | ≤1 µA at VR = 15.2 V - ensures minimal standby power loss in high-impedance bias networks |
| Thermal Resistance | 30°C/W junction-to-TAB 1 - quantifies temperature rise per watt, guiding PCB copper area design |
| ESD Rating | >16 kV HBM - supports robust handling during SMT assembly without external protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4744A | Through-hole DO-41 package; 14 V Zener; 1 W rating; no metallic bottom or locking tabs | Requires manual insertion or wave soldering; unsuitable for high-density SMT layouts | Select when legacy through-hole assembly is mandated and thermal demand is ≤1 W |
| BZX84-C20 | SOT-23 package; 20 V ±5%; 300 mW rating; 25 Ω ZZT; no integrated heat sink | Limited to low-power signal-level clamping; cannot sustain 3 W continuous dissipation | Select only for signal-line protection below 100 mA, not for power rail regulation |
Compared with 1N4744A and BZX84-C20, the 1PMT5932BE3/TR13 uniquely combines 3.0 W SMT power handling, DO-216-compatible footprint, and thermal design features (metallic bottom, locking tabs) - making it the only option for automated, high-reliability, medium-power Zener regulation in space-constrained industrial PCBs.

FAQ
What is the Zener voltage tolerance for 1PMT5932BE3/TR13?
The 1PMT5932BE3/TR13 has a standard Zener voltage tolerance of ±5% at 20 V, measured at IZT = 18.7 mA and TAB temperature = 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, but the base part number 1PMT5932BE3/TR13 specifies ±5%.
Can 1PMT5932BE3/TR13 be used in place of a 1N4744A?
No - the 1PMT5932BE3/TR13 is not a drop-in replacement for the 1N4744A due to fundamental differences: 1N4744A is a 14 V, 1 W through-hole device in DO-41, while 1PMT5932BE3/TR13 is a 20 V, 3 W surface-mount device in Powermite® (DO-216). Electrical and mechanical incompatibility precludes direct substitution.
What is the maximum reverse leakage current for 1PMT5932BE3/TR13?
The maximum reverse leakage current (IR) for 1PMT5932BE3/TR13 is 1 µA at VR = 15.2 V and TL = 30°C. This value is specified in the Electrical Characteristics table and reflects worst-case leakage under defined test conditions.
How does the Powermite® package improve thermal performance of 1PMT5932BE3/TR13?
The Powermite® package enhances thermal performance of 1PMT5932BE3/TR13 via its full metallic bottom and integral locking tabs, achieving 30°C/W junction-to-TAB thermal resistance. This allows efficient heat transfer directly to the PCB copper, supporting full 3.0 W dissipation at TAB = 60°C - unlike plastic-body SMT diodes with higher thermal resistance.
Is 1PMT5932BE3/TR13 compatible with EIA-481 tape-and-reel standards?
Yes - the 1PMT5932BE3/TR13 is supplied in EIA-481 compliant tape-and-reel packaging, with 3,000 pieces per 7-inch reel and 12,000 pieces per 13-inch reel. This ensures compatibility with standard pick-and-place equipment and automated SMT assembly lines.
