Product details
Overview
1PMT5926B/TR13 from Microsemi is a 11 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 5.5 Ω dynamic impedance at 34.1 mA test current and 1 µA max reverse leakage at 8.4 V. It serves as a precision voltage reference or overvoltage clamp in power supply regulation circuits.
For engineers reviewing the 1PMT5926B/TR13 datasheet, 1PMT5926B/TR13 pinout, 1PMT5926B/TR13 application, or 1PMT5926B/TR13 equivalent, key selection criteria include its 11 V nominal Zener voltage, 3.0 W thermal capability via metallic tab, DO-216 mechanical outline, ESD rating >16 kV HBM, and compatibility with automated SMT assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across load variations and temperature shifts. Its design centers on thermal management: full metallic bottom enables direct PCB heat sinking, and the locking tab acts as an integral thermal path with 30°C/W junction-to-TAB1 resistance.
Electrical behavior is defined by tight knee characteristics-IZK = 0.25 mA and ZZK = 550 Ω-ensuring predictable turn-on below rated current. Reverse leakage remains ≤1 µA up to 8.4 V, supporting low-power biasing and sensing applications where leakage-induced error must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11 V ±5% at IZT = 34.1 mA, TC = 30°C - defines primary regulation point under standard test conditions |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - maximum continuous power handled with specified thermal mounting |
| Dynamic Impedance (ZZT) | 5.5 Ω at IZT = 34.1 mA - low AC impedance ensures minimal output voltage variation under dynamic load changes |
| Knee Current (IZK) | 0.25 mA - minimum current needed to enter stable Zener conduction region |
| Reverse Leakage (IR) | ≤1 µA at VR = 8.4 V - guarantees negligible standby current in high-impedance bias networks |
| ESD Rating | >16 kV per Human Body Model - supports robust handling in automated manufacturing without external protection |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies thermal path efficiency when mounted to copper pour or heatsink pad |
Pinout & Package
The 1PMT5926B/TR13 uses a DO-216 molded surface-mount package with a full metallic bottom and integral locking tab (TAB 1) serving as cathode and primary thermal interface. Mounting orientation is unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary current return path and thermal conduction interface; must be soldered to PCB copper for rated 3.0 W operation |
| Lead 2 | Anode | Standard anode connection; electrically isolated from TAB 1; used for forward bias or circuit referencing |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | DO-216 outline with 3.0 W rating-enables high-power Zener functionality in space-constrained layouts without through-hole mounting |
| Full metallic bottom | Eliminates solder flux entrapment during reflow-reduces post-assembly cleaning requirements and void risk |
| Integral heat sink locking tab | TAB 1 provides direct thermal path with 30°C/W resistance-enables reliable 3.0 W operation with minimal PCB copper area |
| ESD robustness | >16 kV HBM-allows direct handling and placement in automated SMT lines without ESD mitigation overhead |
Applications
| Power Supply Voltage Reference | Overvoltage Clamp in DC-DC Converters |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF11A (ON Semiconductor) | 11 V, 1.0 W, SOD-123 package, 10 Ω ZZT, 30°C/W RθJA | Lower power rating limits use to sub-1 W clamping; higher ZZT reduces regulation precision | Select when board space is critical and thermal budget permits lower power handling |
| BZX84-C11 (Diodes Inc.) | 11 V, 300 mW, SOT-23 package, 20 Ω ZZT, no metallic thermal tab | Not suitable for sustained 3.0 W dissipation; requires external heatsinking for >300 mW operation | Select for cost-sensitive, low-power biasing where thermal performance is secondary |
Compared with SMF11A and BZX84-C11, the 1PMT5926B/TR13 delivers 3× higher power handling and 2–4× lower dynamic impedance in a thermally optimized package-making it uniquely suited for high-reliability 12 V rail regulation and clamping where thermal continuity and precision matter.

What is the Zener voltage tolerance for 1PMT5926B/TR13?
The 1PMT5926B/TR13 has a standard Zener voltage tolerance of ±5% at 11 V, measured at 34.1 mA test current and TAB 1 temperature of 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D respectively, but the base part number 1PMT5926B/TR13 ships with ±5%.
How is thermal performance achieved in the 1PMT5926B/TR13 package?
The 1PMT5926B/TR13 achieves thermal performance via its Powermite® package: the full metallic bottom and integral locking tab (TAB 1) serve as a direct thermal interface to the PCB. With a specified junction-to-TAB1 thermal resistance of 30°C/W, proper soldering of TAB 1 to a copper pour enables full 3.0 W power dissipation at TAB 1 = 60°C.
Can 1PMT5926B/TR13 be used in automated SMT assembly?
Yes, the 1PMT5926B/TR13 is explicitly designed for compatibility with automatic insertion equipment. Its DO-216 outline, symmetric lead geometry, and flux-trap-free metallic bottom ensure reliable pick-and-place and reflow soldering without process adjustments or post-assembly cleaning.
What is the maximum reverse leakage current for 1PMT5926B/TR13?
The maximum reverse leakage current for 1PMT5926B/TR13 is 1 µA at a reverse voltage of 8.4 V and ambient temperature of 30°C. This low leakage supports use in high-impedance bias networks and precision reference circuits where parasitic current paths must be minimized.
Does 1PMT5926B/TR13 meet industry ESD standards?
Yes, the 1PMT5926B/TR13 has an ESD rating exceeding 16 kV per the Human Body Model (HBM), as confirmed in the official Microsemi datasheet MSC0995. This qualifies it for direct handling and placement in automated manufacturing environments without additional ESD safeguards.
