Product details
Overview
1PMT5950C/TR13 from Microsemi is a 110 V, ±1% tolerance Zener diode in the Powermite® surface-mount package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with 30°C/W thermal resistance from junction to TAB 1 and ESD rating >16 kV HBM - used for precision voltage regulation and overvoltage protection in industrial power supplies and automotive control modules.
For engineers reviewing the 1PMT5950C/TR13 datasheet, 1PMT5950C/TR13 pinout, 1PMT5950C/TR13 application, or 1PMT5950C/TR13 equivalent, key selection criteria include zener voltage tolerance (±1%), dynamic impedance (300 Ω @ IZT = 3.4 mA), knee current (0.25 mA), reverse leakage (≤4000 µA @ VR = 83.6 V), and thermal performance under PCB-mounted conduction cooling.
Technical Context
This Zener diode operates as a two-terminal voltage reference device with cathode designated by TAB 1, requiring no external biasing circuitry. Its full metallic bottom enables direct thermal coupling to the PCB ground plane, and the locking tab provides mechanical retention during reflow while acting as an integral heat sink.
The device is characterized at TL = 30°C with VZ measured 20 seconds after DC current application; dynamic impedance is derived using 60 Hz RMS AC current equal to 10% of IZT. It supports automatic insertion equipment and complies with EIA-481 tape-and-reel packaging standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 110 V ±1% (tight tolerance variant denoted by suffix 'C'; ensures stable reference within 1.1 V deviation) |
| Test Current (IZT) | 3.4 mA (operating point where VZ is specified; defines nominal regulation condition) |
| Dynamic Impedance (ZZT) | 300 Ω (low AC impedance at IZT; maintains regulation stability under small-signal load variations) |
| Knee Current (IZK) | 0.25 mA (minimum current to enter regulated region; enables low-power standby regulation) |
| Max Reverse Leakage (IR) | 4000 µA @ VR = 83.6 V (defines upper bound of off-state conduction; critical for high-impedance sensing nodes) |
| Thermal Resistance (RθJ-TAB1) | 30°C/W (junction-to-tab thermal path; enables 3.0 W power handling when TAB 1 is thermally anchored) |
| ESD Rating | >16 kV per Human Body Model (HBM); supports robust handling in automated assembly without additional protection) |
Pinout & Package
Package: Powermite® surface-mount molded package with full metallic bottom and integral locking tab; cathode designated by TAB 1; weight ≈ 0.016 g; compatible with EIA-481 tape-and-reel (13-inch reel: 12,000 pcs).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal and electrical cathode connection; must be soldered to copper pour for thermal management |
| Lead 2 | Anode | Standard anode terminal; electrically isolated from TAB 1; connects to system ground or return path |
Key Features
| Feature | Design Value |
|---|---|
| Powermite® surface-mount package | Enables high-density PCB layout while delivering 3.0 W power handling - comparable to larger DO-216 through-hole devices |
| Full metallic bottom | Eliminates solder flux entrapment during reflow, improving long-term reliability and interfacial thermal contact |
| Integral heat sink locking tab | Provides mechanical retention during automated insertion and enhances thermal conduction from junction to PCB |
| ±1% zener voltage tolerance (suffix 'C') | Reduces calibration overhead in precision reference circuits; eliminates need for post-assembly trimming |
| ESD rating >16 kV HBM | Allows direct handling in standard SMT lines without ESD mitigation steps or protective circuitry |

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 |
|---|---|---|---|
| 1N5950BRLG | Same 110 V nominal VZ, but ±5% tolerance and DO-41 through-hole package; higher RθJA (~75°C/W) | Requires through-hole mounting and board real estate; unsuitable for high-density SMT designs | Select only if legacy through-hole compatibility or cost sensitivity outweighs SMT density and thermal needs |
| BZX85C110 | 110 V ±5%, 1.3 W rating, DO-41 package; no metallic tab or locking feature; RθJA ≈ 100°C/W | Limited to lower-power applications; lacks ESD robustness (>16 kV HBM) and thermal anchoring capability | Acceptable only for non-critical, low-duty-cycle reference use where PCB space and thermal margin are not constrained |
Compared with 1PMT5950C/TR13, both alternatives lack ±1% tolerance, surface-mount thermal anchoring, and ESD robustness - making them unsuitable for high-reliability, high-density, or automotive-grade implementations where 1PMT5950C/TR13 delivers verified regulation stability and manufacturability.

FAQ
What does the 'C' suffix in 1PMT5950C/TR13 indicate?
The 'C' suffix in 1PMT5950C/TR13 specifies ±1% zener voltage tolerance, distinguishing it from the standard ±5% version (1PMT5950B). This tighter tolerance is confirmed in Note 1 of the MSC0995.PDF datasheet and directly impacts reference accuracy in precision analog circuits. The 1PMT5950C/TR13 achieves this via post-process binning and is validated at TL = 30°C with measurement performed 20 seconds after DC current application.
How is thermal management implemented for 1PMT5950C/TR13?
Thermal management for 1PMT5950C/TR13 relies on conduction through TAB 1, which serves as both cathode and primary heat sink. With a specified junction-to-TAB1 thermal resistance of 30°C/W, the device requires direct soldering of TAB 1 to a copper pour or thermal pad to achieve its full 3.0 W power rating at TAB1 = 60°C. The full metallic bottom eliminates flux entrapment, ensuring consistent thermal interface integrity after reflow.
Is 1PMT5950C/TR13 compatible with automated SMT assembly?
Yes, 1PMT5950C/TR13 is explicitly designed for compatibility with automatic insertion equipment, as stated in the FEATURES section of MSC0995.PDF. Its Powermite® package includes a unique locking tab that secures orientation during placement, and its EIA-481 tape-and-reel packaging (TR13 denotes 13-inch reel) supports high-speed pick-and-place operations without misalignment or tombstoning.
What is the maximum reverse voltage before breakdown for 1PMT5950C/TR13?
The maximum reverse voltage before breakdown for 1PMT5950C/TR13 is defined by its zener voltage VZ = 110 V ±1%, measured at IZT = 3.4 mA. At VR = 83.6 V (the rated reverse voltage), reverse leakage is guaranteed ≤4000 µA. Operation above 110 V initiates controlled avalanche conduction - not destructive breakdown - provided power dissipation remains within 3.0 W limits and thermal design is maintained.
Does 1PMT5950C/TR13 meet automotive qualification standards?
While 1PMT5950C/TR13 is not AEC-Q200 qualified, its specifications - including -55°C to +150°C junction/storage temperature range, >16 kV HBM ESD rating, and robust Powermite® package - align with many automotive subsystem requirements such as engine control unit protection and body electronics. Designers must validate system-level compliance per AEC-Q101 or AEC-Q200 based on full application context, as Microsemi documentation does not declare formal automotive qualification for this part.
