Product details
Overview
1PMT5936B/TR13 from Microsemi is a 30 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 12.5 mA test current, 28 Ω dynamic impedance, and 1 µA max reverse leakage at 22.8 V. It serves as a precision voltage reference or overvoltage clamp in DC power rails and regulator feedback paths.
For engineers reviewing the 1PMT5936B/TR13 datasheet, 1PMT5936B/TR13 pinout, 1PMT5936B/TR13 application, or 1PMT5936B/TR13 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (30°C/W junction-to-TAB), ESD rating (>16 kV HBM), low knee impedance (750 Ω at 0.25 mA), and compatibility with automated SMT assembly using EIA-481 tape-and-reel packaging.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across its specified test current range. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and mechanical stability during reflow soldering.
The device exhibits low reverse leakage (≤1 µA at VR = 22.8 V), stable dynamic impedance (28 Ω at IZT = 12.5 mA), and a defined thermal resistance of 30°C/W from junction to TAB 1 - enabling accurate power derating in high-density PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 30 V ±5% at IZT = 12.5 mA, TL = 30°C - defines nominal regulation point for feedback or clamping circuits |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous DC power handling under defined thermal mounting condition |
| Dynamic Impedance (ZZT) | 28 Ω at IZT = 12.5 mA - determines voltage deviation under load current transients |
| Reverse Leakage (IR) | ≤1 µA at VR = 22.8 V - ensures minimal quiescent current in high-impedance bias networks |
| Thermal Resistance | 30°C/W junction-to-TAB 1 - enables thermal modeling for PCB copper pour sizing and reliability prediction |
| ESD Rating | >16 kV per Human Body Model - supports robustness in handling and end-equipment surge immunity |
| Knee Impedance (ZZK) | 750 Ω at IZK = 0.25 mA - indicates regulation onset behavior near minimum operating current |
Pinout & Package
The 1PMT5936B/TR13 uses a 2-terminal DO-216 surface-mount package with cathode designated by TAB 1. The full metallic bottom serves as both thermal path and mechanical anchor; no separate anode/cathode markings beyond TAB 1 polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal and voltage reference node; must be connected to thermal plane or heatsink pad |
| Opposite Pad | Anode | Current entry point during reverse-bias operation; routed to lower-potential rail or ground |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and reflow while delivering 3.0 W power handling in footprint comparable to smaller diodes |
| Integral heat sink locking tab | Provides mechanical retention and direct thermal path from junction to PCB copper, reducing thermal resistance to 30°C/W |
| Full metallic bottom | Eliminates solder flux entrapment risk during assembly, improving long-term solder joint integrity and reliability |
| ESD robustness | >16 kV HBM rating allows safe handling without special ESD controls and improves system-level surge resilience |
Applications
| DC Power Rail Clamping | Voltage Reference for Feedback Loops |
|---|---|
Use Scenario: Protection of 3.3 V or 5 V logic rails against transient overvoltage events in industrial control modules. IC Role / Device Role / Timing Role: Shunt clamping element that conducts above 30 V to limit voltage excursion and protect downstream ICs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5936BTR | Same 30 V Zener voltage and ±5% tolerance, but in DO-41 through-hole package; higher thermal resistance (~50°C/W) | Requires manual or wave soldering; unsuitable for high-density SMT layouts | Select when board assembly process prohibits SMT or when legacy through-hole design must be maintained |
| BZX84-C30LT1G | 30 V Zener in SOT-23; rated for 300 mW only; dynamic impedance ~90 Ω at 5 mA | Limited to low-power bias/reference use; cannot replace 1PMT5936B/TR13 in 3 W clamping roles | Select only for space-constrained, low-current applications where thermal performance is secondary |
Compared with 1N5936BTR and BZX84-C30LT1G, the 1PMT5936B/TR13 uniquely combines 3.0 W SMT power handling, 30°C/W thermal resistance, and >16 kV ESD rating - making it the only option among the three suitable for high-reliability, high-power, automated production environments requiring robust voltage clamping.

FAQ
What is the Zener voltage tolerance for 1PMT5936B/TR13?
The 1PMT5936B/TR13 has a standard Zener voltage tolerance of ±5% at 30 V, measured at 12.5 mA test current and TAB temperature of 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D respectively, but the TR13 variant ships with the standard ±5% grade unless otherwise specified.
How is thermal performance characterized for 1PMT5936B/TR13?
The 1PMT5936B/TR13 has a thermal resistance of 30°C/W from junction to TAB 1, meaning each watt dissipated raises the junction temperature 30°C above the TAB temperature. This value assumes proper thermal connection of TAB 1 to a sufficient copper area; actual performance depends on PCB layout and ambient conditions.
Can 1PMT5936B/TR13 be used in place of a through-hole Zener like 1N5936B?
No - the 1PMT5936B/TR13 is not a drop-in replacement for 1N5936B due to different packages (DO-216 vs. DO-41), thermal characteristics (30°C/W vs. ~50°C/W), and mounting methods. While both share 30 V Zener voltage and ±5% tolerance, PCB layout and thermal design must be re-validated for the surface-mount 1PMT5936B/TR13.
What is the maximum reverse voltage before significant leakage in 1PMT5936B/TR13?
The 1PMT5936B/TR13 specifies ≤1 µA reverse leakage current at VR = 22.8 V. Beyond this, leakage increases nonlinearly toward the 30 V Zener knee. For stable low-leakage operation, design should keep reverse bias below 22.8 V unless intentional clamping at 30 V is required.
Is 1PMT5936B/TR13 compatible with lead-free reflow profiles?
Yes - the Powermite® package of the 1PMT5936B/TR13 is qualified for standard lead-free reflow soldering (JEDEC J-STD-020). Its molded construction and metallic bottom withstand peak temperatures up to 260°C, and the device meets moisture sensitivity level (MSL) requirements for surface-mount assembly without baking.
