Product details
Overview
1PMT5950A/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 = 60°C, with 300 Ω dynamic impedance at 3.4 mA test current and 16 kV HBM ESD rating. It serves as a precision voltage reference or overvoltage clamp in high-reliability power supply feedback loops and industrial sensor conditioning circuits.
For engineers reviewing the 1PMT5950A/TR13 datasheet, 1PMT5950A/TR13 pinout, 1PMT5950A/TR13 application, or 1PMT5950A/TR13 equivalent, key selection criteria include its 110 V nominal Zener voltage, 3.0 W thermal capability with metallic-tab heatsinking, low reverse leakage (≤1 µA at 83.6 V), DO-216 mechanical outline, and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage regulation across varying load currents. Its Powermite® package integrates a full metallic bottom and locking tab that directly conducts heat from the junction to the PCB pad, achieving 30°C/W thermal resistance from junction to TAB 1.
The device exhibits tight voltage control with ±5% tolerance at 3.4 mA (IZT), 300 Ω dynamic impedance (ZZT), and low knee impedance (ZZK = 0.25 Ω) at IZK = 1 mA - enabling stable regulation even near minimum operating current.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5950B | Same 110 V/3.0 W rating but in DO-41 through-hole package; no metallic tab or locking feature | Lacks integrated heatsinking and SMT compatibility; requires board space and manual or wave-solder process | Select when legacy through-hole assembly or higher mechanical ruggedness is prioritized over thermal density |
| BZX85C110 | 110 V/1.3 W in DO-41; higher ZZT (~500 Ω); no specified HBM ESD rating | Lower power handling limits use to low-energy clamping; not qualified for high-reliability industrial environments | Select only for cost-sensitive, non-critical applications where 3.0 W derating is unnecessary |
Compared with 1N5950B and BZX85C110, the 1PMT5950A/TR13 delivers superior thermal management via its Powermite® tab interface, supports automated SMT production, and provides verified 16 kV ESD immunity - making it the preferred choice for compact, high-reliability, volume-manufactured power systems.

FAQ
What is the Zener voltage tolerance for 1PMT5950A/TR13?
The 1PMT5950A/TR13 has a standard Zener voltage tolerance of ±5% at 3.4 mA test current and TAB 1 temperature of 30°C. Tighter tolerances of ±2% and ±1% are available with suffixes C and D respectively, but the base part number 1PMT5950A/TR13 specifies ±5%. This tolerance directly impacts regulation accuracy in feedback and reference applications.
How is thermal performance managed in the 1PMT5950A/TR13 package?
The 1PMT5950A/TR13 uses the Powermite® package with a full metallic bottom and integral locking tab that serves as both mechanical anchor and primary thermal path. Its junction-to-TAB 1 thermal resistance is 30°C/W, meaning effective heatsinking relies on soldering TAB 1 to adequately sized PCB copper. This design eliminates flux entrapment and enables 3.0 W dissipation at TAB 1 = 60°C.
Is the 1PMT5950A/TR13 compatible with automated SMT assembly?
Yes, the 1PMT5950A/TR13 is fully compatible with automated surface-mount assembly. It ships in EIA-481 compliant tape-and-reel format (13-inch reel, 12,000 pieces), and its DO-216 outline and locking tab ensure stable placement and retention during reflow. The full metallic bottom also prevents solder voids caused by trapped flux - a critical reliability factor in high-volume manufacturing.
What is the maximum reverse voltage before breakdown for 1PMT5950A/TR13?
The 1PMT5950A/TR13 begins regulating at its nominal Zener voltage of 110 V, with a guaranteed minimum breakdown voltage of 104.5 V (−5%) and maximum of 115.5 V (+5%). At reverse voltage VR = 83.6 V - 76% of nominal - reverse leakage is specified ≤1 µA. Operation below this VR value ensures negligible current flow and stable off-state behavior.
Does the 1PMT5950A/TR13 meet any ESD immunity standards?
Yes, the 1PMT5950A/TR13 is rated for >16 kV per the Human Body Model (HBM) ESD test. This high immunity level is confirmed in the official Microsemi datasheet and supports safe handling, automated placement, and field reliability in industrial environments where static discharge is a common failure mechanism. No external ESD protection is required for typical board-level integration.
