Product details
Overview
1PMT5956A/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 feedback loops.
For engineers reviewing the 1PMT5956A/TR13 datasheet, 1PMT5956A/TR13 pinout, 1PMT5956A/TR13 application, or 1PMT5956A/TR13 equivalent, key selection criteria include its 200 V nominal Zener voltage, 3.0 W thermal capability with metallic-tab heatsinking, ESD rating >16 kV HBM, DO-216 mechanical outline, and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This device operates as a silicon planar Zener diode with sharp reverse-breakdown characteristics, designed for stable voltage regulation under DC bias. Its full metallic bottom and integral locking tab provide low thermal resistance (30°C/W junction-to-TAB1) and mechanical retention during reflow.
The 1PMT5956A/TR13 exhibits low reverse leakage (<1 µA at VR = 152 V), tight knee behavior (IZK = 0.25 mA, ZZK = 8000 Ω), and is characterized at TL = 30°C with voltage measurement performed 20 seconds after DC current application per Note 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 200 V ±5% - defines clamping threshold in overvoltage protection circuits |
| Test Current (IZT) | 1.9 mA - operating point where VZ is specified; sets minimum bias for regulation |
| Dynamic Impedance (ZZT) | 1200 Ω - indicates voltage stability under small-signal AC perturbations |
| Max Zener Current (IZM) | 11.6 mA - derived from 3.0 W max power at VZ; limits continuous DC current |
| Thermal Resistance | 30°C/W junction-to-TAB1 - enables direct thermal path to PCB copper pour or heatsink |
| ESD Rating | >16 kV HBM - ensures robustness against handling-induced electrostatic discharge |
| Reverse Leakage (IR) | <1 µA at VR = 152 V - guarantees minimal standby power loss in high-impedance bias networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5956B | Same 200 V VZ and ±5% tolerance, but in DO-41 through-hole package; no metallic tab or locking feature | Lacks thermal performance and SMT compatibility; requires manual insertion and larger board area | Select only if legacy through-hole assembly or higher pulse energy handling without thermal pad is required |
| SMBJ200A | TVS diode with 200 V standoff voltage, 600 W peak pulse power, but higher clamping voltage (224 V) and no regulated Zener curve | Designed for transient suppression, not precision regulation; unsuitable for feedback references | Choose only for surge-only protection; not interchangeable in voltage-reference roles |
Compared with 1N5956B and SMBJ200A, the 1PMT5956A/TR13 uniquely combines SMT manufacturability, 3.0 W steady-state dissipation, and tight Zener regulation-making it optimal for space-constrained, thermally demanding reference and clamp functions where DO-41 or TVS alternatives fall short.

FAQ
What is the Zener voltage tolerance for 1PMT5956A/TR13?
The 1PMT5956A/TR13 has a standard Zener voltage tolerance of ±5% at 200 V nominal, measured at IZT = 1.9 mA with TAB 1 temperature held at 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D respectively, but the base part number 1PMT5956A/TR13 specifies ±5%.
How is thermal management handled in the 1PMT5956A/TR13 package?
The 1PMT5956A/TR13 uses a Powermite® package with a full metallic bottom and integral locking tab that serves as both mechanical anchor and primary thermal conduction path. Its specified thermal resistance is 30°C/W junction-to-TAB1, requiring direct soldering of TAB 1 to a copper thermal pad for effective heat dissipation at its 3.0 W rating.
Is the 1PMT5956A/TR13 compatible with automated SMT assembly processes?
Yes, the 1PMT5956A/TR13 is explicitly designed for compatibility with automatic insertion and reflow soldering equipment. Its Powermite® package conforms to EIA-481 tape-and-reel standards (7-inch reel: 3,000 pcs; 13-inch reel: 12,000 pcs) and features a locking tab that prevents rotation during placement.
What is the maximum reverse leakage current for 1PMT5956A/TR13?
The maximum reverse leakage current (IR) for 1PMT5956A/TR13 is 1 µA at a reverse voltage (VR) of 152 V, as specified in the Electrical Characteristics table. This low leakage supports high-impedance bias networks and precision reference applications where standby current must be minimized.
Does the 1PMT5956A/TR13 meet any ESD immunity standards?
Yes, the 1PMT5956A/TR13 is rated for >16 kV per the Human Body Model (HBM) ESD test, as stated in the FEATURES section. This rating reflects its robustness against electrostatic discharge during handling and board assembly, reducing risk of latent damage in production environments.
