Product details
Overview
1PMT5932B/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 15.2 mA maximum Zener current - used for precision voltage regulation and overvoltage protection in compact DC power rails.
For engineers reviewing the 1PMT5932B/TR13 datasheet, 1PMT5932B/TR13 pinout, 1PMT5932B/TR13 application, or 1PMT5932B/TR13 equivalent, key selection criteria include its DO-216 mechanical outline, full metallic bottom for flux-free reflow, integral heat sink tab, 30°C/W junction-to-tab thermal resistance, and ESD rating >16 kV HBM.
Technical Context
This Zener diode operates as a two-terminal voltage reference device, conducting in reverse breakdown to clamp or regulate voltage across load circuits. Its cathode is unambiguously designated by TAB 1, and it functions reliably across -55°C to +150°C junction temperature range.
The device delivers stable 20 V regulation under 18.7 mA test current (IZT), with low knee current (IZK = 0.25 mA) and tight 14 Ω dynamic impedance (ZZT), enabling accurate regulation even near knee region. Reverse leakage remains ≤1 µA at VR = 1 V.
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 production-grade tolerance. |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous power handling with thermal derating above 60°C. |
| Dynamic Impedance | 14 Ω at IZT = 18.7 mA - determines regulation sensitivity to current changes; lower value improves voltage stability. |
| Junction-to-Tab Thermal Resistance | 30°C/W - quantifies thermal path efficiency from die to mounting tab, critical for heatsinking design. |
| ESD Rating | >16 kV per Human Body Model - ensures robustness against electrostatic discharge during handling and assembly. |
| Reverse Leakage | ≤1 µA at VR = 1 V - confirms minimal off-state conduction, preserving low-power standby integrity. |
| Knee Current | 0.25 mA - specifies minimum current needed to enter useful regulation region; enables low-current biasing. |
Pinout & Package
Package: DO-216 molded surface-mount package with full metallic bottom and integral heat sink locking tab (cathode designated by TAB 1). Dimensions conform to Microsemi Powermite® mechanical specification; weight ≈ 0.016 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal and electrical cathode connection; must be soldered to copper pour for thermal management. |
| Lead 2 | Anode | Standard anode connection; mounted opposite TAB 1 in DO-216 outline; no thermal function. |
Key Features
| Feature | Design Value |
|---|---|
| Full metallic bottom | Eliminates solder flux entrapment during reflow, improving solder joint reliability and process yield. |
| Integral heat sink locking tab | Provides direct thermal path from junction to PCB copper, reducing thermal resistance by anchoring TAB 1 to heatsink area. |
| DO-216 mechanical outline | Enables automated pick-and-place compatibility and high-density board layout without lead bending or trimming. |
| ±5% Zener tolerance (standard) | Meets cost-sensitive industrial regulation needs; tighter 2% (suffix C) and 1% (suffix D) options available. |

FAQ
What is the Zener voltage tolerance of the 1PMT5932B/TR13?
The 1PMT5932B/TR13 has a standard Zener voltage tolerance of ±5% at 20 V nominal, measured at IZT = 18.7 mA and TAB 1 temperature of 30°C. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available upon request, but the base 1PMT5932B/TR13 part carries the ±5% specification.
How is the cathode identified on the 1PMT5932B/TR13 package?
The cathode of the 1PMT5932B/TR13 is unambiguously designated by TAB 1 - the larger metallic terminal on the DO-216 package. This tab serves both as the cathode electrical connection and the primary thermal path to the PCB, and must be soldered to an adequate copper area for thermal management.
What is the maximum power dissipation for the 1PMT5932B/TR13, and under what conditions?
The 1PMT5932B/TR13 is rated for 3.0 W DC power dissipation when TAB 1 temperature is maintained at 60°C. Derating is required above this temperature - for example, at TAB 1 = 100°C, maximum dissipation drops to approximately 1.8 W - based on its 30°C/W junction-to-tab thermal resistance.
Does the 1PMT5932B/TR13 meet any ESD immunity standards?
Yes, the 1PMT5932B/TR13 is rated for >16 kV per the Human Body Model (HBM) ESD test, as confirmed in the Microsemi MSC0995 datasheet. This level of ESD robustness supports safe handling and assembly in standard manufacturing environments without additional protection circuitry.
Is the 1PMT5932B/TR13 compatible with automated surface-mount assembly processes?
Yes, the 1PMT5932B/TR13 is fully compatible with automated insertion and reflow processes. Its DO-216 Powermite® package features a unique locking tab and full metallic bottom that prevent solder flux entrapment and ensure reliable placement and solder joint formation per EIA-481 tape-and-reel standards.
