Product details
Overview
1PMT5956/TR7 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-voltage DC power supplies and industrial control circuits.
For engineers reviewing the 1PMT5956/TR7 datasheet, 1PMT5956/TR7 pinout, 1PMT5956/TR7 application, or 1PMT5956/TR7 equivalent, key selection criteria include its 200 V Zener voltage, 3.0 W thermal capability with metallic-tab heat sinking, DO-216 mechanical outline, and ESD rating >16 kV HBM - critical for ruggedized power management designs.
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, enabling stable 3.0 W operation without external heatsinking.
The device exhibits low reverse leakage (IR ≤ 1 µA at VR = 152 V), 30°C/W junction-to-TAB thermal resistance, and is characterized at TL = 30°C with voltage measurement performed 20 seconds after DC current application per Note 1 - ensuring repeatable, production-ready calibration behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 200 V ±5% at IZT = 1.9 mA - defines precise clamping threshold for overvoltage protection circuits |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-energy transient suppression without derating in compact layouts |
| Dynamic Impedance (ZZT) | 1200 Ω at IZT - indicates moderate regulation stiffness; suitable for non-critical reference but robust for clamping |
| Max Reverse Leakage (IR) | 1 µA at VR = 152 V - ensures minimal standby current in high-impedance bias networks |
| Junction-to-TAB Rθ | 30°C/W - allows direct thermal path to PCB copper, supporting reliable 3 W operation with standard FR4 |
| ESD Rating | >16 kV HBM - provides inherent handling robustness during SMT assembly and field deployment |
Pinout & Package
Package: Powermite® (DO-216) surface-mount molded package with full metallic bottom and integral locking tab; cathode designated by TAB 1; weight ≈ 0.016 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal and electrical cathode connection; must be soldered to thermal pad for rated 3.0 W operation |
| Lead 2 | Anode | Standard anode termination; mounted opposite TAB 1 per DO-216 mechanical drawing |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and reflow while delivering 3.0 W capability in footprint comparable to smaller discrete packages |
| Integral heat sink locking tab | Mechanically anchors device during reflow and conducts heat directly from junction to PCB, reducing thermal resistance by ~40% vs. standard SOD packages |
| Full metallic bottom | Eliminates solder flux entrapment risk during assembly, improving long-term reliability and void-free solder joint formation |
| ESD rating >16 kV HBM | Reduces need for upstream ESD protection components in end-equipment, simplifying BOM for industrial interfaces |
Applications
| Industrial Power Supply Protection | High-Voltage Sensor Biasing |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5388BRLG | 200 V, 5 W, DO-201AD package; higher power but larger footprint and no metallic tab | Requires larger PCB area and external heatsinking for sustained 3 W operation | Choose when higher peak power margin is needed and space permits |
| BZX85C200-TR | 200 V, 1.3 W, DO-41; lower power, axial lead, no thermal tab | Limited to intermittent clamping; unsuitable for continuous 3 W thermal loads | Choose only for low-duty-cycle protection where cost and legacy through-hole compatibility are priorities |
Compared with 1N5388BRLG and BZX85C200-TR, the 1PMT5956/TR7 uniquely delivers 3.0 W in a surface-mount DO-216 outline with integrated thermal tab - enabling compact, reflow-compatible, high-reliability clamping where board space and thermal performance are constrained.

FAQ
What is the Zener voltage tolerance for 1PMT5956/TR7?
The 1PMT5956/TR7 has a standard Zener voltage tolerance of ±5% at 200 V, measured at IZT = 1.9 mA with TAB 1 temperature held at 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D respectively, but the base 1PMT5956/TR7 part uses the ±5% grade. This tolerance is verified per Microsemi's test methodology described in MSC0995.PDF Rev F.
Can 1PMT5956/TR7 be used in reflow soldering processes?
Yes, the 1PMT5956/TR7 is qualified for standard lead-free reflow soldering per J-STD-020. Its Powermite® package features a full metallic bottom that promotes uniform heating and eliminates solder flux entrapment - critical for achieving void-free joints. The device's -55°C to +150°C junction/storage temperature range supports typical reflow thermal profiles without degradation.
What is the maximum continuous power dissipation for 1PMT5956/TR7?
The 1PMT5956/TR7 is rated for 3.0 W DC power dissipation when TAB 1 is maintained at 60°C, as specified in the Maximum Ratings table of MSC0995.PDF. This rating assumes proper thermal design - i.e., TAB 1 soldered to a minimum 100 mm² copper pad - and accounts for voltage rise at higher currents per Micro Note 202. Derating is required above 60°C TAB temperature.
How is the cathode identified on 1PMT5956/TR7?
The cathode of the 1PMT5956/TR7 is designated by TAB 1, as confirmed in the Mechanical Characteristics section of MSC0995.PDF. This metallic tab serves both as the cathode electrical connection and the primary thermal path. The anode is the opposing lead (Lead 2), and polarity must be observed during PCB layout to ensure correct reverse-bias operation.
Does 1PMT5956/TR7 meet any ESD immunity standards?
Yes, the 1PMT5956/TR7 has an ESD rating exceeding 16 kV per the Human Body Model (HBM), as stated in the FEATURES section of MSC0995.PDF. This level of robustness is intrinsic to the device structure and packaging, and does not require external protection circuitry during handling or in-system operation - making it suitable for use in environments with high electrostatic discharge risk.
