Product details
Overview
1PMT5925C/TR13 from Microsemi is a 10 V, ±1% tolerance surface-mount Zener diode in the Powermite® package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with 4.5 mA test current, 450 Ω dynamic impedance, and <5 µA reverse leakage at 8.0 V. It serves as a precision voltage reference or overvoltage clamp in power supply regulation circuits.
For engineers reviewing the 1PMT5925C/TR13 datasheet, 1PMT5925C/TR13 pinout, 1PMT5925C/TR13 application, or 1PMT5925C/TR13 equivalent, key selection criteria include its tight 1% Zener voltage tolerance, low 450 Ω dynamic impedance at 4.5 mA, ESD rating >16 kV HBM, full metallic bottom for flux-free soldering, and thermal resistance of 30°C/W junction-to-TAB1.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across its specified current range (IZK = 0.25 mA to IZM = 247.5 mA). Its Powermite® package integrates a locking tab that functions as both mechanical anchor and thermal path to TAB 1, enabling efficient heat transfer under sustained 3.0 W dissipation.
The device exhibits low knee impedance (ZZK = 500 Ω) and maintains stable Zener voltage (VZ = 10.0 V ±1%) at TL = 30°C, with forward voltage of 1.2 V at 200 mA - confirming robust bidirectional surge handling capability and suitability for bidirectional transient suppression where forward conduction may occur.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 10.0 V ±1% - enables precision voltage reference within 0.1 V error band at IZT = 4.5 mA |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - supports high-energy clamping without external heatsink in compact layouts |
| Dynamic Impedance | 450 Ω at IZT - ensures minimal output voltage variation under load current changes |
| Reverse Leakage | <5 µA at VR = 8.0 V - guarantees low standby power loss in always-on protection circuits |
| Thermal Resistance | 30°C/W junction-to-TAB1 - allows accurate thermal derating using TAB temperature measurement |
| ESD Rating | >16 kV HBM - provides intrinsic robustness against handling and system-level electrostatic discharge |
Pinout & Package
Package: Powermite® surface-mount molded package with full metallic bottom and integral locking tab; cathode designated by TAB 1; mounting position unrestricted; weight ≈ 0.016 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal and electrical cathode connection; must be thermally anchored to PCB copper for rated power operation |
| Lead 2 | Anode | Standard anode connection; electrically isolated from TAB 1; used for circuit return path in Zener bias configuration |
Key Features
| Feature | Design Value |
|---|---|
| Full metallic bottom | Eliminates solder flux entrapment during reflow, improving long-term reliability and reducing post-assembly cleaning requirements |
| Integral heat sink locking tab | Provides mechanical retention during automated insertion and doubles as primary thermal interface to PCB ground plane |
| ±1% Zener voltage tolerance (suffix C) | Reduces need for post-production trimming or binning in precision reference designs |
| Low reverse leakage (<5 µA @ 8 V) | Minimizes quiescent current draw in battery-powered or energy-harvesting systems |
Applications
| Power Supply Voltage Reference | Overvoltage Clamp in DC-DC Converters |
|---|---|
Use Scenario: Stable 10 V reference for feedback loop of isolated flyback or forward converters. IC Role / Device Role / Timing Role: Precision shunt regulator providing error signal to optocoupler or controller IC. Use Value: ±1% tolerance ensures output regulation within ±0.1 V, supporting tighter output specs without additional calibration. | Use Scenario: Protection against input surge transients on 12 V rail feeding synchronous buck controller. IC Role / Device Role / Timing Role: Fast-acting shunt clamp limiting voltage to 10.5 V before downstream IC damage occurs.

IC Role / Device Role / Timing Role: Low-leakage shunt element absorbing ESD pulses before TVS diode triggers. Use Value: >16 kV HBM rating provides first-line defense without degrading signal integrity due to sub-µA leakage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10LT1G | 250 mW rating, SOT-23 package, 10 V ±5%, 15 Ω Zzt at 5 mA | Lower power handling; unsuitable for >250 mW continuous clamping | Select when board space is critical and power demand is ≤250 mW |
| SMBJ10A | 600 W peak power TVS, unidirectional, 10.0 V standoff, 17.0 V clamping | Transient-only suppression; not a precision reference; higher clamping voltage | Select for surge-only protection where precise DC regulation is not required |
Compared with BZX84-C10LT1G and SMBJ10A, the 1PMT5925C/TR13 uniquely combines 3.0 W steady-state dissipation, ±1% DC voltage accuracy, and integrated thermal management - making it the only option among the three suitable for precision, high-power shunt regulation.

FAQ
What is the Zener voltage tolerance of 1PMT5925C/TR13?
The "C" suffix in 1PMT5925C/TR13 denotes ±1% Zener voltage tolerance at 10.0 V nominal, verified per Microsemi's test conditions (IZT = 4.5 mA, TL = 30°C). This tighter tolerance eliminates post-manufacturing calibration in precision reference designs and is confirmed in Note 1 of the MSC0995.PDF datasheet.
How is thermal performance defined for 1PMT5925C/TR13?
1PMT5925C/TR13 has a junction-to-TAB1 thermal resistance of 30°C/W, with rated 3.0 W dissipation valid only when TAB 1 temperature is maintained at 60°C. This requires direct thermal coupling of TAB 1 to PCB copper; exceeding TAB temperature limits reduces safe operating current per the derating curve in the datasheet.
Is 1PMT5925C/TR13 compatible with automated SMT assembly?
Yes, 1PMT5925C/TR13 is explicitly designed for compatibility with automatic insertion equipment. Its Powermite® package features a unique locking tab and full metallic bottom that prevent misalignment and flux entrapment during reflow - both confirmed in the "FEATURES" and "Mechanical Specifications" sections of MSC0995.PDF.
What does the "TR13" suffix indicate in 1PMT5925C/TR13?
The "TR13" suffix indicates tape-and-reel packaging per EIA Standard 481 on a 13-inch reel containing 12,000 units. This format supports high-volume SMT placement and is documented under "PACKAGING" in the MSC0995.PDF datasheet alongside the 7-inch/3,000-piece option.
Can 1PMT5925C/TR13 be used for bidirectional transient suppression?
No - 1PMT5925C/TR13 is a unidirectional Zener diode optimized for reverse-bias regulation. While its forward voltage is 1.2 V at 200 mA, it lacks symmetrical clamping characteristics or specified forward surge ratings. For bidirectional protection, dedicated TVS arrays or back-to-back Zener configurations are required.
