Product details
Overview
1PMT5927C/TR13 from Microsemi is a 12 V ±1% Zener diode in Powermite® surface-mount 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 thermal resistance of 30°C/W junction-to-TAB1. It serves as precision voltage reference and overvoltage clamp in power supply feedback loops and regulator circuits.
For engineers reviewing the 1PMT5927C/TR13 datasheet, 1PMT5927C/TR13 pinout, 1PMT5927C/TR13 application, or 1PMT5927C/TR13 equivalent, key selection criteria include tight 1% voltage tolerance, low 6.5 Ω Zener impedance, ESD rating >16 kV HBM, full metallic bottom for flux-free assembly, 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 550 Ω, ensuring stable regulation even at low bias. Its DO-216 mechanical outline and cathode designation by TAB 1 define unambiguous polarity and mounting orientation.
The device achieves 3.0 W power handling via integral heat sink locking tabs and direct thermal path from junction to metallic TAB 1, enabling reliable operation across -55°C to +150°C junction temperature range without derating below 60°C tab temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5349B | Same 12 V nominal, ±5% tolerance, 5 W rating in DO-204AL package; higher power but larger footprint and no metallic bottom | Used where higher surge energy absorption is required, but board space and flux sensitivity are less critical | Select 1N5349B only if 5 W rating is mandatory and DO-204AL mounting is acceptable |
| BZX84-C12 | 12 V ±5%, SOT-23 package, 300 mW rating, 30 Ω impedance - significantly lower power and higher impedance than 1PMT5927C/TR13 | Suitable for low-power signal-level clamping, not for power rail regulation or high-energy transients | Choose BZX84-C12 only for space-constrained, low-power signal conditioning - not a functional replacement |
Compared with 1N5349B and BZX84-C12, the 1PMT5927C/TR13 uniquely combines 1% tolerance, 3.0 W capability in a flux-resistant surface-mount package with direct thermal path - making it optimal for high-reliability industrial power regulation where precision, power, and manufacturability intersect.

FAQ
What is the Zener voltage tolerance for 1PMT5927C/TR13?
The "C" suffix in 1PMT5927C/TR13 denotes ±1% Zener voltage tolerance at 31.2 mA test current and 30°C tab temperature. This is tighter than the standard ±5% (B suffix) and supports precision voltage reference designs without post-assembly calibration. The 1PMT5927C/TR13 achieves this via tighter process control during wafer fabrication and binning.
How is thermal management handled in the 1PMT5927C/TR13 package?
The 1PMT5927C/TR13 uses its metallic TAB 1 as the primary thermal conduction path, with a specified junction-to-TAB thermal resistance of 30°C/W. For optimal performance, TAB 1 must be soldered to a minimum 100 mm² copper pour on the PCB. This design eliminates reliance on lead-frame conduction and enables full 3.0 W dissipation at TAB 1 ≤ 60°C - a key advantage over conventional SOD-123 or SOT-23 Zeners.
Is the 1PMT5927C/TR13 compatible with lead-free reflow processes?
Yes, the 1PMT5927C/TR13 is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260°C. Its molded Powermite® package and full metallic bottom prevent delamination and flux entrapment during high-temperature profiles. The device's -55°C to +150°C operating range remains fully valid after lead-free assembly, supporting automotive and industrial applications.
What does the "TR13" suffix indicate in 1PMT5927C/TR13?
The "TR13" suffix indicates tape-and-reel packaging per EIA-481 standard on a 13-inch reel containing 12,000 units. This format is optimized for high-volume automated placement equipment. The carrier tape features precise pocket geometry and cover tape peel strength calibrated for consistent pick-and-place yield - a requirement confirmed in Microsemi's application note AN-1022 for Powermite® devices.
Can 1PMT5927C/TR13 replace older through-hole Zeners like 1N4742A in new designs?
Yes, the 1PMT5927C/TR13 can replace 1N4742A (12 V, ±5%, 1 W) in new SMT designs, offering 3× higher power rating, 1% vs. 5% tolerance, superior thermal performance, and ESD robustness. However, it is not a drop-in replacement due to different package (DO-216 vs. DO-41) and polarity marking (TAB 1 cathode vs. band). Layout redesign and thermal pad implementation are required for full benefit.
