Product details
Overview
1PMT5936A/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 compact DC power rails and regulator feedback paths.
For engineers reviewing the 1PMT5936A/TR13 datasheet, 1PMT5936A/TR13 pinout, 1PMT5936A/TR13 application, or 1PMT5936A/TR13 equivalent, key selection criteria include Zener voltage tolerance, 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 EIA-481 tape-and-reel automated assembly.
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 or wave soldering.
The device exhibits low reverse leakage (≤1 µA at VR = 22.8 V) and a well-defined knee region (IZK = 0.25 mA, ZZK = 750 Ω), enabling stable clamping in low-current bias networks and precision reference circuits where low quiescent current matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 30 V ±5% at IZT = 12.5 mA - defines nominal regulation point for feedback or clamp design |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous power handling under defined thermal mounting condition |
| Dynamic Impedance (ZZT) | 28 Ω at IZT = 12.5 mA - determines output voltage variation under load current changes |
| Knee Impedance (ZZK) | 750 Ω at IZK = 0.25 mA - indicates regulation quality near turn-on, critical for low-current references |
| Reverse Leakage (IR) | ≤1 µA at VR = 22.8 V - ensures minimal error current in high-impedance bias networks |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies temperature rise per watt, guiding heatsinking and layout decisions |
| ESD Rating | >16 kV per Human Body Model - supports robustness in handling and board-level ESD environments |
Pinout & Package
Package: Powermite® (DO-216AA), molded surface-mount package with full metallic bottom and integral heat-sink locking tab; cathode designated by TAB 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat path and electrical cathode connection; must be soldered to copper pour for thermal and electrical performance |
| Lead 2 | Anode | Standard anode terminal; mounted opposite TAB 1, electrically isolated from package body |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and reflow while delivering 3.0 W power handling in footprint smaller than DO-41 |
| Integral heat-sink locking tab | Improves thermal transfer to PCB copper and prevents rotation during insertion or reflow |
| Full metallic bottom | Eliminates solder flux entrapment risk and enhances thermal conductivity vs. plastic-bottom SMD packages |
| ESD robustness | >16 kV HBM rating reduces need for external protection in board-level ESD-prone applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5936A | Same 30 V, ±5%, 3.0 W rating but in DO-41 through-hole package; higher thermal resistance (~50°C/W) | Requires manual or wave-solder assembly; unsuitable for high-density SMT layouts | Select when legacy through-hole design or prototyping with breadboard-friendly leads is required |
| BZX84-C30 | 30 V, ±5%, 300 mW SOT-23 package; lower power, higher ZZT (~50 Ω), no metallic heat tab | Limited to low-power signal-level clamping; cannot sustain 3.0 W dissipation | Select only for space-constrained signal conditioning where power stress is negligible |
Compared with 1N5936A and BZX84-C30, the 1PMT5936A/TR13 uniquely delivers 3.0 W SMT power handling with integrated thermal management-enabling compact, high-reliability clamping in industrial power interfaces where thermal performance and automated assembly are mandatory.

FAQ
What is the Zener voltage tolerance for 1PMT5936A/TR13?
The 1PMT5936A/TR13 has a standard Zener voltage tolerance of ±5% at 30 V, measured at IZT = 12.5 mA and TAB 1 temperature of 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D, respectively, but the base 1PMT5936A/TR13 uses the ±5% grade.
How is thermal performance characterized for 1PMT5936A/TR13?
The 1PMT5936A/TR13 has a junction-to-TAB1 thermal resistance of 30°C/W. This value assumes direct soldering of TAB 1 to a sufficient copper area on the PCB. The 3.0 W power rating is valid only when TAB 1 temperature is maintained at ≤60°C, making thermal pad design essential for reliable operation.
Is 1PMT5936A/TR13 compatible with lead-free reflow processes?
Yes, the 1PMT5936A/TR13 Powermite® package is qualified for standard lead-free reflow profiles (JEDEC J-STD-020). Its molded construction and metallic bottom support thermal cycling reliability, and the device meets Microsemi's specifications for peak reflow temperatures up to 260°C.
What does the "TR13" suffix indicate in 1PMT5936A/TR13?
The "TR13" suffix denotes tape-and-reel packaging per EIA-481 standard on a 13-inch reel containing 12,000 units. This format is optimized for high-speed pick-and-place equipment and supports automated manufacturing without manual handling or static exposure risks.
Can 1PMT5936A/TR13 be used in place of a 1N5936A in an existing design?
No direct substitution is recommended without layout and thermal review. While both share identical electrical specs (30 V, ±5%, 3.0 W), the 1PMT5936A/TR13 uses a surface-mount Powermite® package versus the 1N5936A's axial DO-41. PCB footprint, thermal relief, and assembly process differ significantly-requiring redesign for the SMT variant.
