Product details
Overview
1PMT5925CE3/TR13 from Microsemi is a 10 V, ±5% tolerance Zener diode in Powermite® surface-mount package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with 4.5 mA test current (IZT), 450 Ω dynamic impedance (ZZT), and 8.0 mA maximum Zener current (IZM). It serves as a precision voltage reference or overvoltage clamp in DC power rails of industrial control modules.
For engineers reviewing the 1PMT5925CE3/TR13 datasheet, 1PMT5925CE3/TR13 pinout, 1PMT5925CE3/TR13 application, or 1PMT5925CE3/TR13 equivalent, key selection criteria include its DO-216 footprint, full metallic bottom for flux-free reflow, integral heat sink tab, 16 kV HBM ESD rating, and thermal resistance of 30°C/W junction-to-TAB1.
Technical Context
This Zener diode operates in reverse breakdown mode to regulate or clamp voltage at 10 V nominal with ±5% tolerance. Its Powermite® package integrates TAB 1 as cathode and primary thermal path, enabling 3.0 W dissipation when mounted on a 60°C heatsink pad.
Electrical behavior is defined at TL = 30°C with IZT = 4.5 mA; knee current IZK = 0.25 mA ensures stable regulation onset, while ZZK = 500 Ω reflects low-voltage turn-on impedance. Reverse leakage IR ≤ 5 µA at VR = 5 V confirms tight leakage control for low-power biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10 V ±5% - precise clamping threshold for 12 V rail protection or reference generation |
| Test Current (IZT) | 4.5 mA - operating point where VZ and ZZT are specified; sets minimum bias for stable regulation |
| Dynamic Impedance (ZZT) | 450 Ω - small-signal AC resistance affecting regulation accuracy under varying load |
| Max Power Dissipation | 3.0 W at TAB 1 = 60°C - thermal limit dictating heatsink pad size and layout copper area |
| Thermal Resistance | 30°C/W junction-to-TAB1 - enables thermal modeling of junction temperature rise under load |
| ESD Rating | >16 kV HBM - robustness against handling discharge without parameter shift or failure |
| Knee Current (IZK) | 0.25 mA - lowest current ensuring measurable Zener conduction; critical for low-current bias networks |

FAQ
What is the Zener voltage tolerance for 1PMT5925CE3/TR13?
The 1PMT5925CE3/TR13 has a nominal Zener voltage of 10 V with a standard tolerance of ±5%, as confirmed in the MSC0995.PDF datasheet. This tolerance applies at IZT = 4.5 mA and TL = 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, but the CE3 variant specifies ±5%.
How is thermal management implemented in the 1PMT5925CE3/TR13 package?
The 1PMT5925CE3/TR13 uses its metallic TAB 1 as both cathode and primary thermal conduction path, achieving 30°C/W junction-to-TAB thermal resistance. The full metallic bottom eliminates flux entrapment, and the locking tab enhances mechanical and thermal contact to the PCB copper pour-enabling 3.0 W dissipation at TAB 1 = 60°C without external heatsinks.
What is the maximum reverse leakage current for 1PMT5925CE3/TR13?
The 1PMT5925CE3/TR13 exhibits a maximum reverse leakage current (IR) of 5 µA at VR = 5 V, per the Electrical Characteristics table in MSC0995.PDF. This low leakage supports stable biasing in high-impedance analog circuits and low-power sleep-mode applications where quiescent current must remain minimal.
Is 1PMT5925CE3/TR13 compatible with standard SMT reflow processes?
Yes, the 1PMT5925CE3/TR13 is fully compatible with standard lead-free reflow profiles. Its Powermite® package is designed for automatic insertion equipment and conforms to EIA-481 tape-and-reel standards (7″ reel: 3,000 pcs; 13″ reel: 12,000 pcs). The full metallic bottom prevents flux entrapment, reducing post-reflow cleaning requirements and defect risk.
What does the "E3/TR13" suffix indicate in 1PMT5925CE3/TR13?
The "E3" denotes compliance with JEDEC J-STD-020 moisture sensitivity level (MSL) 3, and "TR13" specifies packaging on a 13-inch tape-and-reel carrier containing 12,000 units. This suffix confirms factory-standard handling, storage, and assembly readiness per industry moisture and logistics protocols-critical for high-volume manufacturing of the 1PMT5925CE3/TR13.
