Product details
Overview
1PMT5926AE3/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 1 µA max reverse leakage at 8.4 V. It serves as a precision voltage reference or overvoltage clamp in DC power rails of industrial control modules.
For engineers reviewing the 1PMT5926AE3/TR7 datasheet, 1PMT5926AE3/TR7 pinout, 1PMT5926AE3/TR7 application, or 1PMT5926AE3/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, and compatibility with automated SMT assembly per EIA-481 tape-and-reel packaging.
Technical Context
This Zener diode operates in reverse breakdown mode to regulate or clamp voltage with tight voltage stability across temperature (–55°C to +150°C junction/storage range). Its Powermite® package integrates a full metallic bottom and locking tab for mechanical retention and thermal conduction to PCB copper.
The device delivers 11 V nominal regulation at 34.1 mA (IZT), exhibits 5.5 Ω dynamic impedance (ZZT), and maintains ≤1 µA reverse leakage (IR) up to 8.4 V (VR), enabling stable reference performance in low-noise analog supply monitoring circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5926B | Same 11 V ±5%, but in DO-41 through-hole package; no metallic bottom or locking tab; 500 mW rating | Suitable only for low-power prototyping or legacy through-hole designs; lacks thermal performance for 3 W SMT use | Select 1PMT5926AE3/TR7 when automated SMT assembly, 3 W dissipation, or PCB thermal conduction are required |
| MMSZ5242B | 12 V ±5%, SOD-123 package, 500 mW rating, 10 Ω ZZT, 100 nA IR at 9.1 V | Better leakage and smaller footprint, but insufficient power handling for 12 V rail clamping above 100 mA | Choose 1PMT5926AE3/TR7 where sustained 34.1 mA regulation or transient 3 W clamping is needed |

FAQ
What is the zener voltage tolerance for 1PMT5926AE3/TR7?
The 1PMT5926AE3/TR7 has a standard zener voltage tolerance of ±5% at 11 V nominal, 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 E3/TR7 variant specifies ±5%. This tolerance is maintained across its operating temperature range of –55°C to +150°C.
How is thermal management handled in the 1PMT5926AE3/TR7 package?
The 1PMT5926AE3/TR7 uses the Powermite® package with a full metallic bottom and integral locking tab that directly conducts heat from the junction to the PCB copper pad. Its specified thermal resistance is 30°C/W junction-to-TAB, enabling reliable 3.0 W operation when TAB 1 is soldered to an adequately sized thermal pad. No external heatsink is required under these conditions.
Is the 1PMT5926AE3/TR7 compatible with automated SMT assembly processes?
Yes, the 1PMT5926AE3/TR7 is designed for full compatibility with automated insertion and reflow processes. It ships in EIA-481 standard tape-and-reel format (7-inch reel, 3,000 pieces), and its Powermite® package features a locking tab that prevents rotation or displacement during pick-and-place. The full metallic bottom also eliminates solder flux entrapment, improving solder joint quality and process yield.
What is the maximum reverse leakage current for 1PMT5926AE3/TR7?
The maximum reverse leakage current (IR) for 1PMT5926AE3/TR7 is 1 µA at a reverse voltage (VR) of 8.4 V, tested at TL = 30°C. This low leakage supports energy-efficient operation in always-on circuits such as battery-backed real-time clocks or sensor bias networks where standby current must remain below 1 µA.
Does the 1PMT5926AE3/TR7 meet any ESD immunity standards?
Yes, the 1PMT5926AE3/TR7 is rated for >16 kV electrostatic discharge per the Human Body Model (HBM), as confirmed in the official Microsemi MSC0995 datasheet. This level of ESD robustness allows safe handling during manufacturing and improves system-level resilience against user-induced ESD events in end equipment like industrial HMIs or automotive infotainment interfaces.
