Product details
Overview
1PMT5927B/TR7 from Microsemi is a 12 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 6.5 Ω dynamic impedance at 31.2 mA test current and 1 µA max reverse leakage at 9.1 V. It serves as a precision voltage reference or overvoltage clamp in DC power rails of industrial control modules.
For engineers reviewing the 1PMT5927B/TR7 datasheet, 1PMT5927B/TR7 pinout, 1PMT5927B/TR7 application, or 1PMT5927B/TR7 equivalent, key selection criteria include zener voltage tolerance, thermal resistance (30°C/W junction-to-TAB), ESD rating (>16 kV HBM), low knee impedance (550 Ω at 0.25 mA), and compatibility with EIA-481 tape-and-reel automated assembly.
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.
The device exhibits low reverse leakage (≤1 µA at VR = 9.1 V), stable dynamic impedance (6.5 Ω at IZT = 31.2 mA), and a thermal resistance of 30°C/W from junction to TAB 1 - enabling reliable operation up to +150°C junction temperature.
Key Specifications

|---|---|
| Zener Voltage | 12 V ±5% at IZT = 31.2 mA - defines regulated output voltage under nominal bias |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous power handling with thermal derating |
| Dynamic Impedance | 6.5 Ω at IZT - determines voltage regulation stability under load transients |
| Knee Impedance | 550 Ω at IZK = 0.25 mA - indicates regulation onset sharpness near minimum operating current |
| Reverse Leakage | ≤1 µA at VR = 9.1 V - ensures minimal standby current in clamping or reference circuits |
| Thermal Resistance | 30°C/W junction-to-TAB 1 - enables thermal design using TAB as primary heat path |
| ESD Rating | >16 kV per HBM - supports robust handling in automated SMT lines without special ESD controls |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF12A (ON Semiconductor) | 12 V, 400 W peak pulse power, 1.5 kW surge rating; SOD-123FL package; 100 Ω dynamic impedance | Optimized for transient suppression, not precision regulation; higher leakage (5 µA) | Select for surge-heavy environments where clamping speed matters more than voltage stability |
| BZX84-C12 (Diodes Inc.) | 12 V, ±5%, 300 mW power, SOT-23 package; 20 Ω dynamic impedance; no metallic thermal tab | Limited to low-power biasing; lacks thermal path for sustained 3 W operation | Select only for space-constrained, low-current reference use where thermal performance is secondary |
Compared with SMF12A and BZX84-C12, the 1PMT5927B/TR7 uniquely balances 3.0 W continuous regulation, 6.5 Ω dynamic impedance, and integrated thermal conduction - making it suitable for high-reliability 12 V reference or clamping where both precision and power endurance are required.

FAQ
What is the zener voltage tolerance for 1PMT5927B/TR7?
The 1PMT5927B/TR7 has a nominal zener voltage of 12 V with a standard tolerance of ±5%, measured at IZT = 31.2 mA and TAB temperature = 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D, but the TR7 variant uses the standard ±5% grade.
How is thermal management handled in the 1PMT5927B/TR7 package?
The 1PMT5927B/TR7 uses the Powermite® package with TAB 1 as the cathode and primary thermal conduction path. Its junction-to-TAB thermal resistance is 30°C/W, and the full metallic bottom ensures efficient heat transfer to the PCB copper pour - critical for sustaining 3.0 W dissipation without exceeding +150°C junction temperature.
Can 1PMT5927B/TR7 be used in automated SMT assembly lines?
Yes, the 1PMT5927B/TR7 is fully compatible with automated insertion equipment. Its Powermite® package features a unique locking tab that aids pick-and-place accuracy, and its EIA-481 tape-and-reel packaging (7″ reel, 3,000 pcs) supports high-speed SMT placement without flux entrapment due to the full metallic bottom design.
What is the maximum reverse leakage current for 1PMT5927B/TR7?
The 1PMT5927B/TR7 specifies a maximum reverse leakage current of 1 µA at VR = 9.1 V and TL = 30°C. This low leakage supports stable reference performance in high-impedance analog circuits and minimizes standby power loss in battery-operated systems.
Is the 1PMT5927B/TR7 RoHS compliant and lead-free?
Yes, the 1PMT5927B/TR7 is RoHS compliant and lead-free. Microsemi's Powermite® Zener diodes manufactured after REV F (11/01/99) conform to EU RoHS Directive 2011/65/EU, with lead content below 0.1% by weight and no intentionally added hazardous substances.
