Product details
Overview
1PMT5950AE3/TR7 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 16 kV HBM ESD rating-used for precision voltage regulation and overvoltage protection in industrial power supplies.
For engineers reviewing the 1PMT5950AE3/TR7 datasheet, 1PMT5950AE3/TR7 pinout, 1PMT5950AE3/TR7 application, or 1PMT5950AE3/TR7 equivalent, key selection criteria include zener voltage tolerance, thermal resistance (30°C/W junction-to-TAB), reverse leakage (<4000 µA at 83.6 V), compatibility with EIA-481 tape-and-reel automation, and full metallic bottom for flux-free reflow assembly.
Technical Context
This device operates as a voltage-reference and clamping element in DC power rails, leveraging its tight 110 V ±5% zener voltage specification and low knee impedance (≤1200 Ω at IZK = 0.25 mA) to maintain stable regulation under varying load conditions. Its Powermite® package integrates a locking tab acting as an integral heat sink and features a full metallic bottom to prevent solder flux entrapment during SMT reflow.
The 1PMT5950AE3/TR7 exhibits 1.2 V forward voltage at 200 mA and maintains operation across -55°C to +150°C junction temperature range. Thermal resistance of 30°C/W (junction-to-TAB1) enables effective power dissipation up to 3.0 W when TAB1 is thermally anchored-critical for high-reliability industrial and telecom power management circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 110 V ±5% at IZT = 3.4 mA - defines precise clamping threshold for overvoltage protection circuits |
| Power Dissipation | 3.0 W at TAB1 = 60°C - supports robust thermal handling without external heatsink when mounted on copper pad |
| Dynamic Impedance (ZZT) | 300 Ω at IZT = 3.4 mA - ensures minimal voltage deviation under small-signal current variations |
| Knee Impedance (ZZK) | 1200 Ω at IZK = 0.25 mA - guarantees stable regulation onset near minimum operating current |
| Reverse Leakage (IR) | <4000 µA at VR = 83.6 V - limits standby power loss in high-impedance bias networks |
| ESD Rating | >16 kV per HBM - eliminates need for external ESD protection in board-level surge environments |
| Thermal Resistance | 30°C/W junction-to-TAB1 - enables direct thermal coupling to PCB copper for passive cooling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5365B | Same 110 V nominal zener voltage but in DO-204AL (DO-41) through-hole package; 5 W rating; higher thermal resistance (50°C/W) | Requires PCB hole drilling and wave soldering; unsuitable for high-density SMT layouts | Select only if legacy through-hole assembly or higher power margin (>3 W) is required |
| BZX84-C110 | 110 V ±5% in SOT-23; 300 mW rating; 10× lower power handling; 250 Ω ZZT at 5 mA | Limited to signal-level clamping; cannot sustain 3.0 W transient energy | Use only for low-power bias/reference where thermal constraints prohibit Powermite® footprint |
Compared with 1N5365B and BZX84-C110, the 1PMT5950AE3/TR7 uniquely delivers 3.0 W SMT-compatible power handling with integrated thermal management-making it the sole option for space-constrained, high-energy clamping in industrial and telecom infrastructure.

FAQ
What is the zener voltage tolerance of the 1PMT5950AE3/TR7?
The 1PMT5950AE3/TR7 has a standard zener voltage tolerance of ±5% at 110 V nominal, measured at IZT = 3.4 mA with TAB1 held at 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D respectively, but the E3/TR7 variant specifies ±5%. This tolerance directly impacts regulation accuracy in feedback and protection circuits.
How is thermal management handled in the 1PMT5950AE3/TR7 package?
The 1PMT5950AE3/TR7 uses the Powermite® package with an integral locking tab (TAB 1) serving as both cathode and primary heat sink. Its 30°C/W junction-to-TAB thermal resistance requires direct soldering of TAB 1 to a thermally robust PCB copper area to achieve the full 3.0 W power rating-no external heatsink is needed if layout guidelines are followed.
Is the 1PMT5950AE3/TR7 compatible with automated SMT assembly processes?
Yes-the 1PMT5950AE3/TR7 is supplied in EIA-481 compliant tape-and-reel format (3,000 pieces per 7-inch reel), designed specifically for compatibility with high-speed pick-and-place equipment. Its full metallic bottom prevents flux entrapment during reflow, ensuring reliable solder joint formation without post-process cleaning.
What is the maximum reverse leakage current for the 1PMT5950AE3/TR7?
The 1PMT5950AE3/TR7 has a maximum reverse leakage current of 4000 µA at VR = 83.6 V (75% of VZ). This value is critical for low-power bias networks and timing circuits where excessive leakage could cause timing errors or increased quiescent current-verified per Microsemi's MSC0995 datasheet Rev F.
Does the 1PMT5950AE3/TR7 have ESD protection built-in?
Yes-the 1PMT5950AE3/TR7 is rated for >16 kV per Human Body Model (HBM), eliminating the need for discrete ESD protection components in many board-level applications. This rating is intrinsic to the device structure and confirmed in the "Features" section of the official Microsemi datasheet MSC0995.
