Product details
Overview
1PMT5952BE3/TR13 from Microsemi is a 130 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 450 Ω dynamic impedance at 2.9 mA test current and 18.1 mA maximum Zener current. It serves as a precision voltage reference or overvoltage clamp in industrial power supply feedback loops.
For engineers reviewing the 1PMT5952BE3/TR13 datasheet, 1PMT5952BE3/TR13 pinout, 1PMT5952BE3/TR13 application, or 1PMT5952BE3/TR13 equivalent, key selection criteria include its 130 V nominal Zener voltage, 3.0 W thermal capability via metallic tab, DO-216 mechanical outline, ESD rating >16 kV HBM, and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This device operates as a two-terminal voltage-regulating diode with cathode designated by TAB 1. Its Zener voltage is specified at IZT = 2.9 mA and TL = 30°C, with dynamic impedance measured using 60 Hz RMS AC superimposed at 10% of IZT.
The Powermite® package provides junction-to-tab thermal resistance of 30°C/W and full metallic bottom to prevent solder flux entrapment. It supports automatic insertion equipment and permits mounting in any orientation, with mechanical dimensions conforming to DO-216 outline.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 130 V ±5% at IZT = 2.9 mA - defines stable clamping/reference point in regulation circuits |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-energy transient suppression without heatsink in compact layouts |
| Dynamic Impedance (ZZT) | 450 Ω at IZT = 2.9 mA - indicates voltage stability under small-signal current variation |
| Max Zener Current (IZM) | 18.1 mA - derived from 3.0 W limit and VZ, sets safe continuous operating ceiling |
| Thermal Resistance (RθJ-TAB) | 30°C/W - quantifies temperature rise per watt at the metallic tab, critical for thermal design |
| ESD Rating | >16 kV per Human Body Model - ensures robustness during handling and board assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5375B | 130 V, 5 W, DO-201AD package, RθJ-A = 20°C/W - higher power but larger footprint and no integral tab heat sink | Requires heatsinking for sustained 3 W operation; less suitable for ultra-compact SMT layouts | Select when higher power headroom is needed and board space allows through-hole or larger SMT package |
| BZX84-C130 | 130 V, 300 mW, SOT-23 package, RθJ-A ≈ 300°C/W - orders-of-magnitude lower power rating | Only viable for signal-level clamping or low-current references; cannot handle 3 W transients | Select only for low-power bias or protection where thermal mass is not required |
Compared with 1N5375B and BZX84-C130, the 1PMT5952BE3/TR13 uniquely delivers 3.0 W dissipation in a DO-216 surface-mount form with integrated metallic tab thermal path-enabling high-energy clamping in space-constrained industrial PCBs without external heatsinks or layout redesign.

FAQ
What is the Zener voltage tolerance for 1PMT5952BE3/TR13?
The 1PMT5952BE3/TR13 has a standard Zener voltage tolerance of ±5% at 130 V nominal, measured at IZT = 2.9 mA and TL = 30°C. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available upon request. This tolerance directly impacts regulation accuracy in feedback and reference applications.
How is thermal management handled for 1PMT5952BE3/TR13 in high-power operation?
The 1PMT5952BE3/TR13 relies on its metallic TAB 1 as the primary thermal path, with a specified junction-to-tab thermal resistance of 30°C/W. To achieve the full 3.0 W rating, TAB 1 must be soldered to adequately sized PCB copper area acting as a heat spreader. No external heatsink is required if thermal design guidelines are followed.
Is 1PMT5952BE3/TR13 compatible with automated SMT assembly processes?
Yes, the 1PMT5952BE3/TR13 is designed for compatibility with automated insertion equipment and standard SMT reflow processes. Its DO-216 outline, symmetric geometry, and full metallic bottom eliminate flux entrapment risk-ensuring reliable placement and solder joint integrity in high-volume manufacturing.
What does the "E3/TR13" suffix indicate in 1PMT5952BE3/TR13?
The "E3" denotes compliance with JEDEC J-STD-020 moisture sensitivity level 3 (MSL3), and "TR13" specifies packaging in 13-inch tape-and-reel format containing 12,000 units per reel, conforming to EIA-481 standards. This ensures safe handling, storage, and automated placement for production use.
Can 1PMT5952BE3/TR13 be used as a replacement for axial-lead Zeners like 1N5375B?
The 1PMT5952BE3/TR13 shares the same 130 V Zener voltage as 1N5375B but differs critically in package, thermal path, and power handling. While electrically comparable, it is not a drop-in replacement due to its DO-216 surface-mount footprint and tab-based thermal interface-PCB layout and thermal design must be adapted accordingly.
