Product details
Overview
1PMT5934C/TR7 from Microsemi is a 24 V ±1% Zener diode in Powermite® surface-mount package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with 19 Ω dynamic impedance at 15.6 mA test current and thermal resistance of 30°C/W junction-to-TAB1. It serves as precision voltage reference or overvoltage clamp in DC power rails and regulator feedback paths.
For engineers reviewing the 1PMT5934C/TR7 datasheet, 1PMT5934C/TR7 pinout, 1PMT5934C/TR7 application, or 1PMT5934C/TR7 equivalent, key selection criteria include tight 1% Zener tolerance, ESD rating >16 kV HBM, full metallic bottom for flux-free reflow, and compatibility with automated insertion equipment.
Technical Context
This Zener diode operates in reverse breakdown mode with specified knee current (IZK) of 0.25 mA and knee impedance (ZZK) of 700 Ω, ensuring stable regulation even at low bias. Its DO-216 mechanical outline and cathode designation by TAB 1 define unambiguous PCB layout orientation.
The device achieves 3.0 W power handling via integral heat sink locking tabs and direct thermal path to TAB 1, enabling operation up to +150°C junction temperature while maintaining ≤1 μA reverse leakage at VR = 18.2 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor 1N5355B | 24 V ±5%, 5 W power rating, DO-201AD package, 35 Ω Zzt | Larger through-hole package; higher power but lower regulation precision | Choose when higher surge energy handling is required and SMT is not mandatory |
| Vishay SZ1SMA5924-TP | 24 V ±1%, 1.5 W, SMA package, 25 Ω Zzt, 200 mW max at 25°C | Lower power rating and different thermal profile; no integral heat sink tab | Choose only for low-power, space-constrained designs where 3 W capability is unnecessary |
Compared with 1PMT5934C/TR7, the ON Semiconductor 1N5355B offers greater surge capacity but sacrifices regulation accuracy and SMT compatibility, while the Vishay SZ1SMA5924-TP matches tolerance but lacks thermal performance and mechanical robustness for high-reliability power rail clamping.

FAQ
What is the Zener voltage tolerance for 1PMT5934C/TR7?
The "C" suffix in 1PMT5934C/TR7 denotes ±1% Zener voltage tolerance at IZT = 15.6 mA and TAB temperature of 30°C. This is tighter than the standard ±5% (B suffix) and supports precision voltage reference applications where regulation accuracy is critical. The 1PMT5934C/TR7 maintains this tolerance across its specified operating temperature range.
How is thermal management handled in the 1PMT5934C/TR7 package?
The 1PMT5934C/TR7 uses its metallic TAB 1 as the primary thermal conduction path, with a specified junction-to-TAB thermal resistance of 30°C/W. To achieve rated 3.0 W dissipation, TAB 1 must be soldered to a minimum 100 mm² copper pour. The integral locking tab enhances mechanical stability and improves thermal contact during reflow soldering.
Is the 1PMT5934C/TR7 compatible with lead-free reflow processes?
Yes, the 1PMT5934C/TR7 is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260°C. Its full metallic bottom prevents flux entrapment, reducing voiding risk, and the molded package withstands thermal cycling without delamination. The device meets RoHS Directive 2011/65/EU and is halogen-free.
What does the "TR7" suffix indicate in 1PMT5934C/TR7?
The "TR7" suffix indicates tape-and-reel packaging per EIA-481 standard, with 3,000 units per 7-inch reel. This format is optimized for high-speed automated placement equipment and ensures consistent orientation (cathode marked by TAB 1) during feeding. Reel packaging also supports moisture sensitivity level (MSL) 1 handling without dry pack requirements.
Can the 1PMT5934C/TR7 replace older through-hole Zener diodes like 1N5355B?
The 1PMT5934C/TR7 is not a direct drop-in replacement for 1N5355B due to differing packages (Powermite® DO-216 vs. DO-201AD), thermal paths, and mounting methods. While both provide 24 V Zener regulation, the 1PMT5934C/TR7 requires SMT layout adaptation and delivers superior thermal performance and ESD immunity. System-level validation is required before substitution.
