Product details
Overview
1PMT5926/TR13 from Microsemi is a 11 V, 3.0 W surface-mount Zener diode in the Powermite® package, featuring 34.1 mA test current, 5.5 Ω dynamic impedance at IZT, 8.4 mA maximum Zener current, and 1 µA reverse leakage at 1 V. It serves as a precision voltage reference or overvoltage clamp in DC power rails and regulator feedback loops.
For engineers reviewing the 1PMT5926/TR13 datasheet, 1PMT5926/TR13 pinout, 1PMT5926/TR13 application, or 1PMT5926/TR13 equivalent, key selection criteria include zener voltage tolerance (±5% standard), thermal resistance (30°C/W junction-to-tab), ESD rating (>16 kV HBM), 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 for flux-free soldering and a locking tab that functions as both mechanical anchor and thermal path to PCB copper.
The device exhibits low knee impedance (550 Ω at IZK = 0.25 mA) and stable dynamic impedance (5.5 Ω at IZT = 34.1 mA), enabling reliable clamping and reference performance under varying load and temperature conditions within -55°C to +150°C junction range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11 V ±5% at 34.1 mA - defines regulated output voltage in shunt regulator or clamp circuits |
| Power Dissipation | 3.0 W at TAB1 = 60°C - sets maximum continuous DC power handling with heatsinking via tab |
| Dynamic Impedance (ZZT) | 5.5 Ω at IZT - determines voltage deviation under small-signal AC load variations |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies temperature rise per watt dissipated through metal tab |
| ESD Rating | >16 kV HBM - ensures robustness against electrostatic discharge during handling and assembly |
| Reverse Leakage (IR) | 1 µA max at VR = 1 V - confirms low standby current in high-impedance bias networks |
| Knee Current (IZK) | 0.25 mA - minimum current needed to enter useful regulation region near VZ |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5343B | Same 11 V nominal, but 5 W rating and DO-201AD package; higher thermal resistance (25°C/W vs 30°C/W) | Requires larger PCB footprint and different reflow profile due to axial leaded package | Select when higher power margin is required and through-hole assembly is acceptable |
| BZX84-C11 | 11 V, 300 mW SOT-23 package; lower power, higher ZZT (20 Ω), no metallic tab for heatsinking | Limited to low-power signal-level clamping; unsuitable for sustained 3 W dissipation | Select only for space-constrained, low-current bias/reference use where thermal performance is secondary |
Compared with 1N5343B and BZX84-C11, the 1PMT5926/TR13 uniquely combines 3 W power handling, SMT compatibility, and integrated thermal tab-making it optimal for compact, high-reliability power rail protection where board area and thermal management are critical.

FAQ
What is the Zener voltage tolerance for 1PMT5926/TR13?
The 1PMT5926/TR13 has a standard Zener voltage tolerance of ±5% at 11 V, measured at 34.1 mA test current and TAB1 temperature of 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D respectively, but the base part number 1PMT5926/TR13 ships with ±5% specification as documented in MSC0995 Rev F.
Can 1PMT5926/TR13 be used in reflow soldering processes?
Yes, the 1PMT5926/TR13 is qualified for standard SMT reflow processes. Its Powermite® package features a full metallic bottom compatible with EIA-481 tape-and-reel packaging and is designed for automated insertion and Pb-free reflow profiles. The device's -55°C to +150°C junction temperature range supports typical reflow thermal excursions.
What is the thermal resistance of 1PMT5926/TR13, and how is it measured?
The 1PMT5926/TR13 has a thermal resistance of 30°C/W junction-to-TAB1, meaning each watt dissipated raises the junction temperature 30°C above the tab temperature. This value is measured with TAB1 held at 60°C under DC power dissipation conditions and reflects direct conduction from die to the metallic tab, not ambient air.
Does 1PMT5926/TR13 have polarity marking, and how is cathode identified?
Yes, the 1PMT5926/TR13 uses TAB 1 as the cathode terminal, clearly designated in the mechanical drawings and electrical specifications. The cathode is marked by the larger metallic tab; the opposite lead is the anode. Correct orientation is essential for proper Zener operation in reverse-bias configurations.
What is the maximum reverse leakage current for 1PMT5926/TR13 at 1 V?
The maximum reverse leakage current for 1PMT5926/TR13 is 1 µA at VR = 1 V, as specified in the Electrical Characteristics table of MSC0995 Rev F. This low leakage supports use in high-impedance bias networks and precision reference applications where standby current must be minimized.
