Product details
Overview
1PMT5932C/TR13 from Microsemi is a 20 V, ±1% tolerance Zener diode in the Powermite® surface-mount 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-DC converter feedback loops.
For engineers reviewing the 1PMT5932C/TR13 datasheet, 1PMT5932C/TR13 pinout, 1PMT5932C/TR13 application, or 1PMT5932C/TR13 equivalent, key selection criteria include zener voltage tolerance (±1%), power derating above 60°C, low reverse leakage (<1 µA at 15.2 V), ESD robustness (>16 kV HBM), and compatibility with automated SMT assembly using EIA-481 tape-and-reel packaging.
Technical Context
This Zener diode operates as a two-terminal voltage reference device, leveraging silicon PN-junction breakdown characteristics to maintain stable reverse-bias voltage across its cathode (TAB 1) and anode terminals. Its Powermite® package integrates a full metallic bottom and locking tab that serves as both mechanical anchor and thermal path to PCB copper.
The device exhibits tight voltage regulation under defined test conditions: VZ = 20.0 V ±1% measured at IZT = 18.7 mA with TL = 30°C, ZZT = 14 Ω, and IZK = 0.25 mA at VZK = 16.7 V - enabling reliable knee-region operation in low-current biasing and sensing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 20.0 V ±1% - precise reference for feedback networks requiring <1% initial error |
| Test Current | 18.7 mA - defines operating point where VZ and ZZT are specified |
| Dynamic Impedance | 14 Ω - low AC impedance ensures minimal voltage shift under load transients |
| Max Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-power regulation without external heatsink |
| Thermal Resistance | 30°C/W junction-to-TAB1 - supports thermal design with direct tab-to-copper conduction |
| ESD Rating | >16 kV HBM - withstands handling and board-level electrostatic discharge events |
| Reverse Leakage | <1 µA at 15.2 V - ensures negligible quiescent current in standby regulation circuits |
Pinout & Package
Powermite® package: molded surface-mount case with full metallic bottom and integral heat-sink locking tab; cathode designated by TAB 1; anode is top metallization; mounting orientation unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C20LT1G | 20 V ±5%, 300 mW, SOT-23 package, ZZT = 50 Ω at 5 mA | Lower power rating limits use to low-current biasing only; no integrated heat sink | Select when space-constrained and power <0.3 W; avoid in 3 W thermal environments |

FAQ
What is the zener voltage tolerance for 1PMT5932C/TR13?
The "C" suffix in 1PMT5932C/TR13 denotes ±1% zener voltage tolerance at 20.0 V, verified per Microsemi's test conditions (IZT = 18.7 mA, TL = 30°C). This tighter tolerance enables direct use in precision feedback loops without external trimming resistors or calibration steps - a key differentiator versus standard ±5% Zeners like the 1PMT5932B variant.
How is thermal performance characterized for 1PMT5932C/TR13?
1PMT5932C/TR13 has a junction-to-TAB1 thermal resistance of 30°C/W, measured with TAB 1 held at 60°C. At full 3.0 W dissipation, this yields a maximum junction temperature of 150°C - matching its rated storage/junction limit. Effective thermal design requires direct soldering of TAB 1 to ≥1 cm² of 2-oz copper to sustain continuous operation.
Is 1PMT5932C/TR13 compatible with lead-free reflow processes?
Yes, 1PMT5932C/TR13 is qualified for standard lead-free reflow profiles (JEDEC J-STD-020, peak 260°C). Its Powermite® package uses matte tin plating and thermally stable molding compound, with no moisture sensitivity level (MSL) rating required - eliminating bake requirements prior to assembly.
What does the "TR13" suffix indicate in 1PMT5932C/TR13?
The "TR13" suffix specifies EIA-481 tape-and-reel packaging on a 13-inch reel containing 12,000 units - optimized for high-volume SMT placement equipment. This differs from "TR7", which denotes a 7-inch reel (3,000 units). Both share identical electrical and thermal specifications.
Can 1PMT5932C/TR13 replace 1PMT5932B in existing designs?
Yes, 1PMT5932C/TR13 is a direct drop-in replacement for 1PMT5932B in terms of footprint, thermal interface, and pinout - differing only in tighter ±1% voltage tolerance (vs. ±5%) and same 3.0 W rating. No layout or thermal redesign is needed; however, system-level validation is recommended if the original design relied on the wider tolerance band for margin.
