Product details
Overview
1PMT5950BE3/TR13 from Microsemi is a 110 V, ±5% tolerance Zener diode in the Powermite® surface-mount package, rated for 3.0 W DC power dissipation at TAB 1 temperature of 60°C, with 30°C/W thermal resistance from junction to TAB 1, used for precision voltage regulation and overvoltage protection in power supply rails.
For engineers reviewing the 1PMT5950BE3/TR13 datasheet, 1PMT5950BE3/TR13 pinout, 1PMT5950BE3/TR13 application, or 1PMT5950BE3/TR13 equivalent, key selection criteria include zener voltage tolerance, dynamic impedance (300 Ω at 3.4 mA), knee current (0.25 mA), reverse leakage (≤4000 µA at 83.6 V), and ESD rating (>16 kV HBM).
Technical Context
This device operates as a two-terminal voltage reference with cathode designated by TAB 1, requiring no external biasing. Its full metallic bottom eliminates solder flux entrapment during reflow, and integral locking tabs provide mechanical retention and thermal conduction to the PCB pad.
The 1PMT5950BE3/TR13 delivers stable 110 V regulation under DC conditions with tight thermal coupling to the mounting surface: junction-to-TAB1 thermal resistance is 30°C/W, and maximum junction temperature is +150°C. It meets EIA-481 tape-and-reel packaging standards (7" reel, 3,000 pcs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 110 V ±5% at 3.4 mA test current - defines nominal regulation point with predictable deviation across operating range |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous DC power handling with PCB thermal management |
| Dynamic Impedance (ZZT) | 300 Ω at IZT = 3.4 mA - indicates voltage stability under small-signal AC perturbations |
| Knee Current (IZK) | 0.25 mA - minimum current needed to enter regulated region; critical for low-power standby circuits |
| Reverse Leakage (IR) | ≤4000 µA at VR = 83.6 V - quantifies off-state conduction loss before breakdown |
| Thermal Resistance | 30°C/W junction-to-TAB1 - determines temperature rise per watt dissipated into PCB copper |
| ESD Rating | >16 kV per Human Body Model - ensures robustness against handling and board-level electrostatic discharge |
Pinout & Package
Package: Powermite® surface-mount molded package with full metallic bottom and integral heat-sink locking tab; cathode identified by TAB 1. Mechanical outline matches DO-216 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat path and voltage reference terminal; must be connected to ground or low-impedance return for thermal and electrical performance |
| Lead 2 | Anode | Current entry point during reverse-bias operation; connects to unregulated input rail |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and reflow assembly while delivering 3.0 W power handling in compact footprint |
| Full metallic bottom | Eliminates solder flux entrapment during reflow, improving long-term reliability and void-free solder joints |
| Integral heat-sink locking tab | Provides mechanical anchoring and direct thermal conduction path from junction to PCB copper |
| ESD robustness | >16 kV HBM rating reduces risk of field failure due to electrostatic discharge during handling or operation |
| Tight voltage tolerance option | ±5% standard; 2% (suffix C) and 1% (suffix D) available for high-precision regulation applications |
Applications
| Industrial Power Supply Regulation | Automotive ECU Overvoltage Clamp |
|---|---|
Use Scenario: Stabilizing reference voltage in isolated DC-DC converter feedback loops where primary-side sensing requires high-voltage tolerance. IC Role / Device Role / Timing Role: Zener diode acting as shunt voltage reference and transient clamp on secondary-side auxiliary bias rail. Use Value: Maintains regulation accuracy within ±5% across -55°C to +150°C ambient, supported by 30°C/W thermal resistance to PCB. | Use Scenario: Protecting microcontroller I/O pins and sensor interfaces from load-dump transients up to 120 V in 12 V automotive systems. IC Role / Device Role / Timing Role: Fast-response overvoltage clamp placed between supply rail and ground, triggered above 110 V nominal breakdown. Use Value: Limits clamping voltage to ≤121.6 V at 21.5 mA peak current while surviving >16 kV HBM ESD events. |
| Telecom Line Card Protection | Medical Equipment Reference Stability |
Use Scenario: Safeguarding Ethernet PHY interfaces and PoE controllers against induced surges on long-line telecom connections. IC Role / Device Role / Timing Role: Standby-mode shunt regulator that activates only during overvoltage events, minimizing quiescent power draw. Use Value: Draws ≤4000 µA leakage at 83.6 V, enabling low-power standby compliance without sacrificing protection threshold. | Use Scenario: Providing stable excitation voltage for precision analog front-ends in portable diagnostic equipment with strict thermal constraints. IC Role / Device Role / Timing Role: Low-drift voltage reference source with minimal self-heating due to 30°C/W thermal resistance and 3.0 W rating. Use Value: Enables <100 ppm/°C effective drift via PCB copper area design, leveraging full metallic bottom for uniform thermal distribution. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5365B | Same 110 V nominal, but DO-41 through-hole package; 5 W rating; higher thermal resistance (~50°C/W) | Requires manual or wave-solder assembly; less suitable for high-density SMT layouts | Select when legacy through-hole compatibility or higher power margin is required over SMT integration |
| SMBJ110A | TVS diode with 110 V standoff, 122 V breakdown, 600 W peak pulse rating - not a precision Zener | Designed for surge suppression, not steady-state regulation; higher leakage and looser voltage tolerance | Select only for transient-only protection; avoid where stable DC reference or low-leakage operation is needed |
Compared with 1PMT5950BE3/TR13, 1N5365B offers higher power headroom but lacks SMT compatibility and thermal efficiency, while SMBJ110A provides superior surge handling but cannot replace it in precision regulation roles due to fundamental functional differences.

FAQ
What is the zener voltage tolerance for 1PMT5950BE3/TR13?
The 1PMT5950BE3/TR13 has a standard zener voltage tolerance of ±5% at 110 V nominal, measured at 3.4 mA test current with TAB 1 held at 30°C. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available upon request, but the base part number 1PMT5950BE3/TR13 ships with ±5%.
How is thermal performance specified for 1PMT5950BE3/TR13?
The 1PMT5950BE3/TR13 specifies a junction-to-TAB1 thermal resistance of 30°C/W, meaning each watt dissipated raises the junction temperature 30°C above the TAB 1 temperature. Maximum junction temperature is +150°C, and 3.0 W power dissipation is rated at TAB 1 = 60°C - requiring adequate PCB copper area for heat spreading.
Is 1PMT5950BE3/TR13 compatible with lead-free reflow processes?
Yes, the 1PMT5950BE3/TR13 is qualified for lead-free reflow soldering per J-STD-020. Its Powermite® package uses matte tin plating and withstands peak temperatures up to 260°C. The full metallic bottom ensures reliable wetting and minimizes void formation during reflow, consistent with EIA-481 tape-and-reel packaging.
What does the "E3/TR13" suffix indicate in 1PMT5950BE3/TR13?
The "E3" denotes Microsemi's standard environmental compliance (lead-free, RoHS-compliant finish), and "TR13" specifies tape-and-reel packaging on a 13-inch reel containing 12,000 units per reel, conforming to EIA-481 standards. This differs from the "TR7" variant, which uses a 7-inch reel with 3,000 units.
Can 1PMT5950BE3/TR13 be used as a replacement for older through-hole Zeners like 1N5365B?
While 1PMT5950BE3/TR13 shares the same 110 V nominal zener voltage as 1N5365B, it is not a drop-in replacement due to its surface-mount Powermite® package versus DO-41 through-hole. Electrical characteristics differ: 1PMT5950BE3/TR13 has lower power rating (3.0 W vs. 5 W) and superior thermal resistance (30°C/W vs. ~50°C/W), making it suitable only where SMT layout and thermal design accommodate its form factor and ratings.
