Product details
Overview
1PMT5956E3/TR13 from Microsemi is a 200 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 1.9 mA test current (IZT), 1200 Ω dynamic impedance (ZZT), and 11.6 mA maximum Zener current (IZM). It serves as a precision voltage reference or overvoltage clamp in high-reliability power supply regulation circuits.
For engineers reviewing the 1PMT5956E3/TR13 datasheet, 1PMT5956E3/TR13 pinout, 1PMT5956E3/TR13 application, or 1PMT5956E3/TR13 equivalent, key selection criteria include its 200 V nominal Zener voltage, 3.0 W thermal capability with metallic-tab heat sinking, low reverse leakage (<1 µA at VR = 152 V), ESD rating >16 kV HBM, and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across its specified IZT–IZM range. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction from junction to PCB pad, achieving 30°C/W junction-to-TAB1 thermal resistance.
The device exhibits low knee impedance (ZZK = 8000 Ω) and maintains stable regulation under transient load conditions due to its 1.9 mA IZT and 11.6 mA IZM rating. Reverse leakage remains ≤1 µA up to 152 V, supporting reliable clamping in high-impedance sensing or protection paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 200 V ±5% - precise clamping threshold for 152–200 V system rails |
| Test Current (IZT) | 1.9 mA - operating point where VZ is guaranteed and ZZT measured |
| Dynamic Impedance (ZZT) | 1200 Ω - small-signal AC resistance affecting regulation stability under ripple |
| Max Zener Current (IZM) | 11.6 mA - peak continuous reverse current before exceeding 3.0 W power limit |
| Thermal Resistance | 30°C/W junction-to-TAB1 - enables direct thermal path to PCB copper for sustained 3 W operation |
| ESD Rating | >16 kV HBM - robust handling during SMT assembly and board-level integration |
| Reverse Leakage (IR) | ≤1 µA at VR = 152 V - ensures minimal standby current in high-impedance bias networks |
Pinout & Package
Powermite® surface-mount package with molded body, full metallic bottom, and integral locking tab acting as cathode terminal (TAB 1). Cathode is designated by TAB 1; anode is the opposing lead. Mounting orientation is unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat sink interface and voltage reference node; must be connected to ground or low-impedance return path |
| Lead 2 | Anode | Current entry point during forward bias; reverse-biased during Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and reflow while delivering 3.0 W power handling comparable to through-hole DO-41 devices |
| Integral heat sink locking tab | Provides mechanical retention and direct thermal conduction path from junction to PCB copper via TAB 1 |
| Full metallic bottom | Eliminates solder flux entrapment risk during reflow, improving long-term reliability and void-free solder joints |
| ESD rating >16 kV HBM | Reduces risk of electrostatic damage during handling, PCB assembly, and field operation without external protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5388B | Same 200 V nominal VZ, but DO-41 through-hole package; 5 W rating; higher IZT (1.5 mA); no metallic tab heat sinking | Requires manual or wave-solder assembly; less suitable for high-density SMT layouts or thermally constrained PCBs | Select when legacy through-hole design or higher pulse power margin is required, not for new SMT designs. |
| BZX85C200 | 200 V VZ, ±5%, but 1.3 W rating in DO-35; IZT = 5 mA; ZZT ≈ 1500 Ω; no integrated heat sink tab | Limited to low-power bias/reference roles; cannot sustain 3.0 W continuous dissipation | Choose only for space-constrained low-power applications where thermal performance is secondary. |

What is the Zener voltage tolerance for 1PMT5956E3/TR13?
The 1PMT5956E3/TR13 has a standard Zener voltage tolerance of ±5% at 200 V nominal, measured at 1.9 mA test current (IZT) with TAB 1 held at 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D, respectively, but the E3 suffix denotes the standard ±5% grade.
How is thermal management handled in the 1PMT5956E3/TR13 package?
The 1PMT5956E3/TR13 uses Microsemi's Powermite® package with a full metallic bottom and integral locking tab (TAB 1) that acts as both cathode and primary heat sink. This design achieves 30°C/W junction-to-TAB1 thermal resistance, allowing the device to safely dissipate its full 3.0 W rating when TAB 1 is properly soldered to adequate PCB copper area.
What is the maximum reverse leakage current for 1PMT5956E3/TR13?
The 1PMT5956E3/TR13 specifies a maximum reverse leakage current (IR) of 1 µA at a reverse voltage (VR) of 152 V, measured at TL = 30°C. This low leakage supports use in high-impedance bias networks and low-power standby circuits without compromising efficiency or accuracy.
Is 1PMT5956E3/TR13 compatible with automated SMT assembly processes?
Yes, the 1PMT5956E3/TR13 is fully compatible with automated insertion and reflow soldering. Its Powermite® package conforms to EIA-481 tape-and-reel standards (7″ reel: 3,000 pcs; 13″ reel: 12,000 pcs) and features a flux-trap-free metallic bottom, ensuring reliable, void-free solder joints in high-volume manufacturing.
What does the "TR13" suffix indicate in 1PMT5956E3/TR13?
The "TR13" suffix in 1PMT5956E3/TR13 indicates tape-and-reel packaging on a 13-inch reel containing 12,000 units, per EIA-481 standard. The "E3" portion denotes the ±5% Zener voltage tolerance grade and confirms compliance with Microsemi's Powermite® mechanical and electrical specifications documented in MSC0995.PDF.
