Product details
Overview
1PMT5926E3/TR7 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-TAB1. It serves as a precision voltage reference or overvoltage clamp in power supply regulation circuits.
For engineers reviewing the 1PMT5926E3/TR7 datasheet, 1PMT5926E3/TR7 pinout, 1PMT5926E3/TR7 application, or 1PMT5926E3/TR7 equivalent, key selection criteria include Zener voltage accuracy, power derating behavior above 60°C, low knee impedance (550 Ω at 0.25 mA), ESD robustness (>16 kV HBM), and compatibility with automated SMT assembly on DO-216 footprint layouts.
Technical Context
This device operates as a silicon planar Zener diode with sharp reverse breakdown at nominal 11 V, designed for stable voltage regulation under varying load and temperature conditions. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and eliminate solder flux entrapment during reflow.
The 1PMT5926E3/TR7 exhibits low reverse leakage (≤1 µA at 8.4 V), tight dynamic impedance control (5.5 Ω at IZT = 34.1 mA), and specified knee characteristics (IZK = 0.25 mA, ZZK = 550 Ω), enabling reliable operation near minimum regulation current.
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 predictable deviation across production lot |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous steady-state power handling before thermal shutdown or degradation |
| Dynamic Impedance (ZZT) | 5.5 Ω at IZT = 34.1 mA - determines output voltage variation under small-signal AC load transients |
| Knee Impedance (ZZK) | 550 Ω at IZK = 0.25 mA - indicates regulation onset sharpness and minimum usable current for stable clamping |
| Thermal Resistance (RθJ-TAB1) | 30°C/W - quantifies junction-to-tab thermal gradient; critical for PCB copper area sizing and thermal relief design |
| ESD Rating | >16 kV per Human Body Model - ensures robustness against handling-induced electrostatic discharge during assembly |
| Reverse Leakage (IR) | ≤1 µA at VR = 8.4 V - limits standby power loss and signal path contamination in high-impedance bias networks |
Pinout & Package
Package: Powermite® (DO-216AA) surface-mount molded 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-sinking terminal and electrical cathode connection; must be connected to ground or low-impedance return path for thermal and electrical performance |
| Lead 2 | Anode | Standard anode connection; mounted opposite TAB 1 on DO-216 footprint; requires standard SMT pad layout per EIA-481 tape-and-reel carrier |
Key Features
| Feature | Design Value |
|---|---|
| Full metallic bottom | Eliminates solder flux entrapment during reflow, preventing post-assembly corrosion or voiding under the package |
| Integral heat sink locking tab | Provides mechanical anchoring and direct thermal path from junction to PCB copper, reducing RθJA by up to 40% vs. standard SOD-123 |
| Automated insertion compatibility | Designed for pick-and-place and reflow processes per EIA-481 tape-and-reel standards (7″/3,000 pcs, 13″/12,000 pcs) |
| Low reverse leakage | ≤1 µA at 8.4 V enables use in ultra-low-power bias networks and battery-backed reference circuits |
Applications
| DC-DC Converter Feedback Reference | Industrial Sensor Signal Clamping |
|---|---|
Use Scenario: Used in the feedback divider of isolated flyback or buck-boost converters to set regulated output voltage. IC Role / Device Role / Timing Role: Precision voltage reference element defining regulation threshold via resistive divider network.

IC Role / Device Role / Timing Role: Bidirectional overvoltage protection device shunting excess energy to ground. Use Value: 16 kV HBM ESD rating and 3.0 W surge capability protect downstream ADCs and op-amps without external TVS cascading. |
| Programmable Logic Supply Clamp | Embedded MCU Reset Circuit |
Use Scenario: Connected between FPGA/CPLD I/O supply rail and ground to suppress switching noise and ESD events. IC Role / Device Role / Timing Role: Low-impedance shunt regulator maintaining rail stability during fast digital transitions.

IC Role / Device Role / Timing Role: Stable voltage reference establishing threshold for comparator-based reset assertion. Use Value: Tight 5.5 Ω ZZT and low 1 µA leakage ensure repeatable 0.8×VDD trip point across temperature and supply variance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4740A | 10 V ±5%, 1.0 W, DO-41 package, RθJA ≈ 100°C/W | Limited to lower-power linear regulators; unsuitable for >150 mA continuous clamp duty | Select when cost sensitivity outweighs thermal performance and SMT compatibility is not required |
| BZX84-C11 | 11 V ±5%, 300 mW, SOT-23 package, ZZT = 20 Ω | Inadequate for >50 mA regulation; higher impedance causes greater output ripple under load | Choose only for space-constrained low-current bias references where thermal margin is non-critical |
Compared with 1N4740A and BZX84-C11, the 1PMT5926E3/TR7 delivers 3× the power handling, 6× lower thermal resistance, and sub-6 Ω impedance-enabling stable regulation in high-current, thermally dense industrial power modules where alternatives would thermally saturate or drift.

FAQ
What is the Zener voltage tolerance for 1PMT5926E3/TR7?
The 1PMT5926E3/TR7 has a standard Zener voltage tolerance of ±5% at 11 V, measured at IZT = 34.1 mA and case temperature TC = 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D respectively, but the base 1PMT5926E3/TR7 conforms strictly to ±5%.
Can 1PMT5926E3/TR7 be used in reflow soldering processes?
Yes, the 1PMT5926E3/TR7 is qualified for standard lead-free reflow profiles per JEDEC J-STD-020. Its Powermite® package features a full metallic bottom that prevents solder flux entrapment, and its thermal rating (−55°C to +150°C storage/junction range) supports repeated thermal cycling without parameter shift or delamination.
What is the maximum reverse leakage current for 1PMT5926E3/TR7?
The maximum reverse leakage current for 1PMT5926E3/TR7 is 1 µA at a reverse voltage of 8.4 V, tested at TL = 30°C. This value is confirmed in the manufacturer's electrical characteristics table and remains valid across the full operating temperature range when derated per thermal resistance specifications.
How does the thermal resistance of 1PMT5926E3/TR7 affect PCB layout?
The 1PMT5926E3/TR7 has a junction-to-TAB1 thermal resistance of 30°C/W. To sustain 3.0 W dissipation, the PCB must provide sufficient copper area connected to TAB 1 to maintain TAB1 ≤ 60°C. A minimum 100 mm² of 1 oz. copper with thermal vias is recommended; insufficient copper will cause thermal derating and potential Zener voltage drift.
Is 1PMT5926E3/TR7 compatible with automated pick-and-place equipment?
Yes, the 1PMT5926E3/TR7 is supplied in EIA-481-compliant tape-and-reel format (7″ reel, 3,000 pieces), with dimensional consistency and surface geometry optimized for vacuum nozzle pickup and placement accuracy. Its locking tab and symmetric lead profile prevent rotation or misalignment during high-speed SMT assembly.
