Product details
Overview
1PMT5926CE3/TR13 from Microsemi is a 11 V, ±5% tolerance Zener diode in Powermite® surface-mount 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 power supply regulation circuits.
For engineers reviewing the 1PMT5926CE3/TR13 datasheet, 1PMT5926CE3/TR13 pinout, 1PMT5926CE3/TR13 application, or 1PMT5926CE3/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 eliminate solder flux entrapment during reflow assembly.
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 below 1 µA up to 8.4 V, supporting low-power standby circuit integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 11 V ±5% at 34.1 mA - defines nominal regulation point with predictable deviation in production |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous power handling before thermal shutdown |
| Dynamic Impedance | 5.5 Ω at IZT - determines output voltage variation under load current changes |
| Knee Current | 0.25 mA - minimum current needed to enter stable regulation region |
| Reverse Leakage | <1 µA at 8.4 V - ensures negligible standby current in clamping or reference applications |
| Thermal Resistance | 30°C/W junction-to-TAB1 - enables accurate junction temperature estimation from tab temperature |
| ESD Rating | >16 kV HBM - provides robustness against handling-induced electrostatic discharge |
Pinout & Package
Package: Powermite® surface-mount molded package with full metallic bottom and integral heat sink locking tab; cathode designated by TAB 1; weight ≈ 0.016 g; DO-216 outline per mechanical drawing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat path and electrical cathode connection; must be thermally anchored to PCB copper for rated power |
| Lead 2 | Anode | Standard anode terminal; mounted opposite TAB 1; no thermal function |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and eliminates through-hole drilling while delivering 3 W power capability in compact footprint |
| Integral heat sink locking tab | Provides direct thermal path from junction to PCB via TAB 1, reducing thermal resistance to 30°C/W |
| Full metallic bottom | Prevents solder flux entrapment during reflow, improving long-term reliability and void-free solder joints |
| ESD rating >16 kV HBM | Eliminates need for external ESD protection in board-level handling and system integration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5926B | Same 11 V zener voltage, but in DO-41 axial package; higher thermal resistance (~65°C/W); no metallic tab | Requires through-hole mounting; unsuitable for high-density SMT layouts or thermal-critical designs | Select only if legacy through-hole assembly or manual prototyping is required |
| MMSZ5240B | 10 V nominal, ±5%, 500 mW rating, SOD-123 package; dynamic impedance ~17 Ω at 20 mA | Limited to low-power applications; cannot replace 1PMT5926CE3/TR13 in 3 W load-clamp roles | Use where space and power constraints permit lower wattage; verify voltage tolerance alignment |
Compared with 1N5926B and MMSZ5240B, the 1PMT5926CE3/TR13 delivers superior thermal performance and SMT compatibility for industrial power regulation, while maintaining tighter regulation stability under varying load conditions.

FAQ
What is the zener voltage tolerance for 1PMT5926CE3/TR13?
The 1PMT5926CE3/TR13 has a standard zener voltage tolerance of ±5% at 11 V, measured at 34.1 mA test current with TAB 1 held at 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D respectively, but the CE3 variant specifies ±5%.
How is thermal management handled in the 1PMT5926CE3/TR13 package?
The 1PMT5926CE3/TR13 uses a Powermite® package with TAB 1 as the cathode and primary thermal path. Its 30°C/W junction-to-tab thermal resistance requires direct thermal connection of TAB 1 to a copper pour or heatsink on the PCB to sustain the full 3.0 W rating at 60°C tab temperature.
Can 1PMT5926CE3/TR13 be used in place of axial-leaded Zeners like 1N5926B?
No - although both have 11 V zener voltage, the 1PMT5926CE3/TR13 is a surface-mount device with integrated heat sinking and different thermal characteristics. Substitution requires PCB layout redesign and thermal validation; it is not a drop-in replacement for through-hole parts like 1N5926B.
What is the maximum reverse leakage current for 1PMT5926CE3/TR13?
The maximum reverse leakage current for 1PMT5926CE3/TR13 is 1 µA at 8.4 V (76% of nominal zener voltage), tested at TL = 30°C. This low leakage supports stable operation in high-impedance reference and sensing applications without introducing significant error current.
Is 1PMT5926CE3/TR13 suitable for automotive applications?
The 1PMT5926CE3/TR13 operates from –55°C to +150°C and meets ESD >16 kV HBM, but it is not AEC-Q200 qualified. For automotive use, additional qualification testing and system-level validation are required; consult Microchip's automotive-grade equivalents if AEC compliance is mandatory.
