Product details
Overview
1PMT5950B/TR13 from Microsemi is a 110 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 300 Ω dynamic impedance at 3.4 mA test current and <4000 µA reverse leakage at 83.6 V. It serves as a precision voltage reference or overvoltage clamp in industrial power supply feedback loops.
For engineers reviewing the 1PMT5950B/TR13 datasheet, 1PMT5950B/TR13 pinout, 1PMT5950B/TR13 application, or 1PMT5950B/TR13 equivalent, key selection criteria include its 110 V nominal Zener voltage, 3.0 W thermal capability with metallic-tab heatsinking, DO-216 mechanical outline, and ESD rating >16 kV HBM - all critical for high-reliability DC rail protection and regulation designs.
Technical Context
This device operates as a two-terminal voltage-regulating diode, with cathode designated by TAB 1 and anode connected to the molded body. Its Zener voltage is specified at 110 V ±5% under 3.4 mA DC test current (IZT) at TL = 30°C, with knee current IZK = 0.25 mA and knee impedance ZZK = 4000 Ω.
Thermal performance is defined by junction-to-TAB1 thermal resistance of 30°C/W, enabling stable operation from –55°C to +150°C. The full metallic bottom and locking tab provide mechanical retention and enhanced heat transfer during reflow or wave soldering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 110 V ±5% at IZT = 3.4 mA - sets precise clamping threshold for 100–120 V DC rails |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables sustained regulation without external heatsink in compact layouts |
| Dynamic Impedance (ZZT) | 300 Ω at IZT - ensures minimal output voltage variation under load transients |
| Reverse Leakage (IR) | <4000 µA at VR = 83.6 V - guarantees low standby power loss in high-impedance bias networks |
| ESD Rating | >16 kV HBM - supports robust handling in automated SMT lines without additional ESD mitigation |
| Thermal Resistance | 30°C/W (junction to TAB 1) - allows accurate thermal design using tab temperature as proxy for junction temp |
| Package | DO-216 (Powermite®) - surface-mount footprint with integral metallic heat sink tab and flux-free assembly |
Pinout & Package
Powermite® package features a molded body with full metallic bottom and locking tab acting as cathode terminal (TAB 1). Mounting orientation is unrestricted; cathode is unambiguously marked by TAB 1 per mechanical drawing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat path and voltage reference node; must be thermally anchored to PCB copper for rated 3.0 W operation |
| Molded Body | Anode | Electrically connected to internal anode structure; solderable surface provides mechanical stability and secondary thermal path |
Key Features
| Feature | Design Value |
|---|---|
| Integral Heat Sink Locking Tab | TAB 1 serves as both cathode and primary thermal interface - eliminates need for separate thermal pad or via stitching |
| Full Metallic Bottom | Prevents solder flux entrapment during reflow/wave soldering - reduces post-assembly cleaning and defect risk |
| DO-216 Mechanical Outline | Standardized footprint compatible with EIA-481 tape-and-reel (7″/13″ reels) - supports high-speed pick-and-place placement |
| 16 kV HBM ESD Rating | Withstands electrostatic discharge events common in automated handling - lowers field failure rate in production environments |
| ±5% Zener Tolerance (Std) | Meets cost-sensitive industrial regulation requirements without requiring tighter-tolerance variants (C/D suffixes) |
Applications
| Industrial Power Supply Feedback | DC Bus Overvoltage Clamp |
|---|---|
Use Scenario: Regulating output voltage in isolated flyback converters using optocoupler feedback. IC Role / Device Role / Timing Role: Zener reference diode providing stable 110 V threshold for TL431-like shunt regulator circuits.

IC Role / Device Role / Timing Role: Precision voltage reference supplying regulated 110 V to amplifier supply rails or reference inputs. Use Value: Enables <0.5% measurement accuracy over –40°C to +85°C ambient due to tight VZ tolerance and low ZZT. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5375B | Same 110 V nominal Zener, but in DO-201AD package; 5 W rating; higher ZZT (400 Ω); no metallic tab | Requires larger PCB area and external heatsinking for 3 W operation; less suitable for dense SMT layouts | Select when higher power margin is needed and board space permits axial/through-hole mounting |
| BZX85C110 | 110 V Zener in DO-41; 1.3 W rating; ±5% tolerance; 500 Ω ZZT; no ESD rating specified | Limited to low-power biasing; unsuitable for clamping >1 W transients or industrial ESD environments | Select only for cost-sensitive, low-stress lab or prototype use where thermal and ESD robustness are secondary |
Compared with 1N5375B and BZX85C110, the 1PMT5950B/TR13 delivers superior thermal management via its metallic-tab Powermite® package, higher ESD immunity (>16 kV vs unspecified), and optimized SMT compatibility - making it the preferred choice for production-grade 110 V regulation in space-constrained, high-reliability systems.

FAQ
What is the Zener voltage tolerance for 1PMT5950B/TR13?
The 1PMT5950B/TR13 has a standard Zener voltage tolerance of ±5% at 110 V nominal, measured at 3.4 mA test current and TAB 1 temperature of 30°C. Tighter tolerances (±2%, ±1%) are available with C and D suffixes, but the base 1PMT5950B/TR13 uses the ±5% specification confirmed in the MSC0995 datasheet revision F.
How is thermal performance defined for 1PMT5950B/TR13?
Thermal performance of the 1PMT5950B/TR13 is defined by a junction-to-TAB1 thermal resistance of 30°C/W. Its 3.0 W power rating applies when TAB 1 is maintained at 60°C, and the full metallic bottom plus locking tab enable direct thermal coupling to PCB copper - eliminating reliance on trace conduction alone.
Is 1PMT5950B/TR13 compatible with automated SMT assembly?
Yes, the 1PMT5950B/TR13 is fully compatible with automated insertion equipment. Its Powermite® package features a DO-216 outline, EIA-481 tape-and-reel packaging (3,000 pcs per 7″ reel), and a locking tab that improves placement accuracy and prevents rotation during pick-and-place - all explicitly stated in the MSC0995 datasheet.
What is the maximum reverse leakage current for 1PMT5950B/TR13?
The maximum reverse leakage current for 1PMT5950B/TR13 is 4000 µA at a reverse voltage of 83.6 V, as specified in the Electrical Characteristics table of the MSC0995 datasheet. This value is measured at TL = 30°C and reflects worst-case leakage under rated clamping conditions.
Does 1PMT5950B/TR13 have an ESD rating, and if so, what is it?
Yes, the 1PMT5950B/TR13 has an ESD rating of >16 kV per the Human Body Model (HBM), as documented in the FEATURES section of the MSC0995 datasheet. This rating applies to the packaged device and supports robust handling in automated SMT lines without requiring additional ESD safeguards during assembly.
