Product details
Overview
1PMT5926E3/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 thermal resistance of 30°C/W junction-to-tab. It serves as a precision voltage reference or overvoltage clamp in DC power rails and analog signal conditioning circuits.
For engineers reviewing the 1PMT5926E3/TR13 datasheet, 1PMT5926E3/TR13 pinout, 1PMT5926E3/TR13 application, or 1PMT5926E3/TR13 equivalent, key selection criteria include zener voltage tolerance, power derating above 60°C, knee current (0.25 mA), reverse leakage (<1 µA at 8.4 V), and ESD robustness (>16 kV HBM).
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 dynamic impedance (5.5 Ω) and low knee impedance (550 Ω), enabling stable regulation even under light-load conditions. Reverse leakage remains ≤1 µA up to 8.4 V, supporting low-power standby circuit integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11 V ±5% at IZT = 34.1 mA, TC = 30°C - defines nominal regulation point with production tolerance band |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - maximum continuous DC power before thermal shutdown or degradation |
| Dynamic Impedance | 5.5 Ω at IZT = 34.1 mA - determines output voltage variation under load current changes |
| Knee Current (IZK) | 0.25 mA - minimum current needed to enter useful regulation region; critical for low-power biasing |
| Reverse Leakage | ≤1 µA at VR = 8.4 V - ensures minimal quiescent current in clamping or reference applications |
| Thermal Resistance | 30°C/W junction-to-TAB1 - enables thermal modeling for PCB copper area and heatsinking requirements |
| ESD Rating | >16 kV per Human Body Model - supports handling without external protection in assembly environments |

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 DO-204AL package; 5 W rating; higher thermal resistance (40°C/W) | Higher power handling but larger footprint and less efficient thermal coupling to PCB | Prefer 1PMT5926E3/TR13 for space-constrained SMT designs requiring optimal thermal performance |
| BZX84-C11 | 11 V ±5%, SOT-23 package; 300 mW rating; 15 Ω dynamic impedance; no metallic thermal tab | Limited to low-power signal-level clamping; unsuitable for >100 mA continuous current | Choose 1PMT5926E3/TR13 where 3.0 W dissipation and robust thermal design are required |
Compared with 1N5343B and BZX84-C11, the 1PMT5926E3/TR13 delivers superior thermal management via its metallic tab and lower dynamic impedance, making it uniquely suited for medium-power SMT voltage regulation where board area and thermal reliability are critical.

FAQ
What is the zener voltage tolerance for 1PMT5926E3/TR13?
The 1PMT5926E3/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 of ±2% (suffix C) and ±1% (suffix D) are available upon request, but the base part number 1PMT5926E3/TR13 reflects the ±5% grade.
How is thermal performance defined for 1PMT5926E3/TR13?
The 1PMT5926E3/TR13 has a junction-to-TAB1 thermal resistance of 30°C/W. Its 3.0 W power rating applies only when TAB 1 is maintained at 60°C; derating is required above that temperature. The full metallic bottom and locking tab enable direct thermal conduction to PCB copper, distinguishing it from standard plastic SMD packages.
Does 1PMT5926E3/TR13 have polarity marking, and how is cathode identified?
Yes, the 1PMT5926E3/TR13 uses TAB 1 as the cathode terminal, clearly designated in the mechanical drawings and electrical specifications. The cathode is physically the larger metal tab, and the anode is the smaller lead. This polarity identification is consistent across all Powermite® Zener diodes in the 1PMT59xx series.
What is the maximum reverse leakage current for 1PMT5926E3/TR13?
The maximum reverse leakage current for 1PMT5926E3/TR13 is 1 µA at a reverse voltage of 8.4 V, as specified in the Electrical Characteristics table. This value is measured at TL = 30°C and confirms suitability for low-quiescent-current applications such as battery-backed reference circuits.
Is 1PMT5926E3/TR13 compatible with standard SMT reflow profiles?
Yes, the 1PMT5926E3/TR13 is qualified for standard lead-free reflow soldering per J-STD-020. Its molded Powermite® package withstands peak temperatures up to 260°C, and the full metallic bottom prevents flux entrapment-reducing voiding risk and improving solder joint reliability during automated assembly.
