Product details
Overview
1PMT5956AE3/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 industrial power supplies.
For engineers reviewing the 1PMT5956AE3/TR13 datasheet, 1PMT5956AE3/TR13 pinout, 1PMT5956AE3/TR13 application, or 1PMT5956AE3/TR13 equivalent, key selection criteria include its 200 V nominal Zener voltage, 3.0 W thermal capability with metallic-tab heat sinking, 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 two-terminal voltage-regulating diode with cathode designated by TAB 1. Its Zener voltage is specified at IZT = 1.9 mA with junction temperature controlled at 30°C, and dynamic impedance measured using 60 Hz RMS AC superimposed at 10% of IZT.
The Powermite® package delivers thermal resistance of 30°C/W from junction to TAB 1, enabling effective heat transfer via the full metallic bottom and integral locking tab acting as a heat sink. Reverse leakage is limited to 1 µA max at VR = 152 V, and forward voltage is 1.2 V at 200 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 200 V ±5% - stable regulation point for high-voltage reference or clamping circuits |
| Test Current (IZT) | 1.9 mA - defined operating point for VZ measurement and impedance characterization |
| Dynamic Impedance (ZZT) | 1200 Ω - indicates voltage stability under small-signal AC variations around IZT |
| Max Zener Current (IZM) | 11.6 mA - maximum DC current before exceeding 3.0 W power limit at TAB 1 = 60°C |
| Thermal Resistance (RθJ-TAB1) | 30°C/W - quantifies junction-to-tab heat transfer efficiency for thermal design margining |
| ESD Rating (HBM) | >16 kV - ensures robustness against handling-induced electrostatic discharge |
| Reverse Leakage (IR) | ≤1 µA at VR = 152 V - low off-state conduction critical for standby power integrity |
Pinout & Package
Package: Powermite® (DO-216), surface-mount molded case with full metallic bottom and integral heat-sink locking tab; cathode identified by TAB 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal; electrically and thermally connected to cathode; must be soldered to PCB copper for thermal performance |

| Full metallic bottom | Eliminates solder flux entrapment during reflow, improving long-term reliability and void-free solder joints |
| Integral heat-sink locking tab | Provides direct thermal path from junction to PCB, reducing RθJ-PCB and supporting sustained 3.0 W operation |
| ESD robustness >16 kV HBM | Reduces risk of field failure due to handling or system-level ESD events without external protection |
| DO-216 mechanical standardization | Ensures compatibility with industry-standard pick-and-place nozzles and stencil apertures |

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 heat-sink tab; RθJ-lead ≈ 65°C/W | Requires manual or wave soldering; unsuitable for high-density SMT layouts or thermal-critical 3 W operation | Select only if legacy through-hole assembly or lower-cost procurement outweighs thermal and automation advantages |
| SMBZ200AL | 200 V VZ, SOD-123FL package, 3.0 W rating, but RθJ-case = 50°C/W; no metallic bottom; ESD = 8 kV HBM | Lacks integral heat-sink tab and full metallic bottom; less robust against flux entrapment and ESD | Prefer when board space is constrained and thermal load is intermittent rather than continuous |
Compared with 1N5956B and SMBZ200AL, the 1PMT5956AE3/TR13 uniquely combines 3.0 W SMT power handling, 30°C/W thermal resistance via TAB 1, and >16 kV ESD immunity-making it optimal for automated, thermally demanding, high-reliability applications where DO-216 footprint and metallic heat sinking are design requirements.

FAQ
What is the Zener voltage tolerance for 1PMT5956AE3/TR13?
The 1PMT5956AE3/TR13 has a standard Zener voltage tolerance of ±5% at 200 V nominal, measured at IZT = 1.9 mA and TAB 1 temperature of 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, but the E3 suffix denotes the standard ±5% version. This tolerance directly impacts voltage regulation accuracy in reference and clamping applications.
How is thermal performance achieved in the 1PMT5956AE3/TR13 Powermite® package?
The 1PMT5956AE3/TR13 achieves thermal performance via its full metallic bottom and integral locking tab (TAB 1), which acts as both cathode and primary heat sink. With a junction-to-TAB1 thermal resistance of 30°C/W, it enables reliable 3.0 W DC power dissipation when TAB 1 is thermally anchored to PCB copper-unlike plastic-bodied SMD Zeners with higher thermal resistance.
Is 1PMT5956AE3/TR13 compatible with standard SMT assembly processes?
Yes, the 1PMT5956AE3/TR13 is fully compatible with standard SMT assembly, including EIA-481 tape-and-reel feeding (13-inch reel, 12,000 pieces), reflow soldering, and automated optical inspection. Its DO-216 outline and locking-tab geometry are optimized for nozzle pickup and placement accuracy, and the full metallic bottom prevents flux entrapment during reflow-reducing post-solder defects.
What is the maximum reverse leakage current for 1PMT5956AE3/TR13 at rated voltage?
The maximum reverse leakage current (IR) for 1PMT5956AE3/TR13 is 1 µA at VR = 152 V (76% of VZ), per the datasheet's Electrical Characteristics table. This low leakage ensures minimal standby power loss and high impedance in off-state operation-critical for precision reference and high-impedance sensing nodes where leakage could introduce error.
Does 1PMT5956AE3/TR13 have a defined polarity marking, and how is it identified?
Yes, 1PMT5956AE3/TR13 uses TAB 1 as the cathode terminal, clearly designated in the Mechanical Characteristics section. The cathode is marked by the larger, metallized tab-visible as the primary mounting surface-and confirmed by the "Cathode designated by TAB 1" statement in the datasheet. No additional band or dot marking is used; orientation is determined solely by tab position.
