Product details
Overview
1PMT5950CE3/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 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 ECUs.
For engineers reviewing the 1PMT5950CE3/TR13 datasheet, 1PMT5950CE3/TR13 pinout, 1PMT5950CE3/TR13 application, or 1PMT5950CE3/TR13 equivalent, key selection criteria include zener voltage tolerance (±5%), 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 in reverse breakdown mode with tightly controlled voltage regulation across its specified test current range. Its Powermite® package integrates a full metallic bottom and locking tab for mechanical stability and thermal conduction to the PCB, enabling reliable operation up to +150°C junction temperature.
The device exhibits low reverse leakage (<4000 µA at 83.6 V) and a defined knee region (IZK = 0.25 mA, ZZK = 0.25 Ω), supporting stable regulation even at low bias currents. Dynamic impedance of 300 Ω at 3.4 mA reflects moderate AC voltage sensitivity near nominal operating point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 110 V ±5% at IZT = 3.4 mA - defines primary regulation setpoint with production-grade tolerance |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - maximum steady-state power handling under conduction-cooled PCB mounting |
| Thermal Resistance | 30°C/W junction-to-TAB 1 - quantifies temperature rise per watt delivered to the metal tab |
| Dynamic Impedance | 300 Ω at IZT = 3.4 mA - indicates small-signal AC voltage variation per mA change in current |
| Knee Current | 0.25 mA - minimum current at which regulation begins to stabilize (ZZK = 0.25 Ω) |
| ESD Rating | >16 kV per Human Body Model - ensures robustness against common electrostatic discharge events during handling and assembly |

Applications
| Industrial Power Supply Regulation | Automotive ECU Overvoltage Clamp |
|---|---|
Use Scenario: Stabilizing reference voltage in isolated DC-DC converter feedback loops operating at 110 V output. IC Role / Device Role / Timing Role: Zener diode provides precise 110 V shunt regulation to maintain output accuracy under load transients. Use Value: ±5% VZ tolerance and 300 Ω dynamic impedance ensure <±1.5 V output deviation across 1–5 mA load variations. | Use Scenario: Clamping transient surges on 12 V/24 V battery rails during load dump events in engine control units. IC Role / Device Role / Timing Role: Acts as fast-responding overvoltage clamp, diverting surge energy to ground before downstream ICs are damaged. Use Value: 3.0 W power rating and 30°C/W thermal resistance enable sustained clamping of 100 ms pulses without thermal runaway. |
| Telecom Line Card Protection | Test Equipment Reference Calibration |
Use Scenario: Protecting analog front-end inputs on telecom line cards exposed to induced lightning surges. IC Role / Device Role / Timing Role: Zener diode placed in series with TVS or as secondary clamp to limit voltage to safe levels for ADC inputs.

IC Role / Device Role / Timing Role: Functions as a passive, non-drifting voltage reference in high-impedance divider networks. Use Value: Tight 5% tolerance and low reverse leakage (<4000 µA @ 83.6 V) minimize drift and loading error in precision measurement paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5950B | Same 110 V nominal VZ, but DO-41 through-hole package; no metallic tab; 60°C/W θJ-A | Lacks integrated heat sinking; unsuitable for high-power-density SMT layouts | Choose 1N5950B only when through-hole assembly is required and thermal budget permits higher junction rise |
| BZX85C110 | 110 V ±5%, 1.3 W rating, DO-41; higher dynamic impedance (500 Ω); no ESD rating specified | Lower power handling limits use to low-duty-cycle clamping or low-current references | Select BZX85C110 where cost is critical and thermal/ESD requirements are relaxed |
Compared with 1N5950B and BZX85C110, the 1PMT5950CE3/TR13 delivers superior thermal performance (30°C/W vs. ≥60°C/W), higher power capability (3.0 W vs. ≤1.3 W), and verified ESD robustness (>16 kV), making it the preferred choice for compact, high-reliability SMT designs.

FAQ
What is the zener voltage tolerance for 1PMT5950CE3/TR13?
The 1PMT5950CE3/TR13 has a nominal zener voltage of 110 V with a standard tolerance of ±5%, as confirmed in the MSC0995.PDF datasheet. This tolerance applies at test current IZT = 3.4 mA and case temperature TC = 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, but the CE3 variant specifies ±5%.
How is thermal performance characterized for 1PMT5950CE3/TR13?
The 1PMT5950CE3/TR13 features a thermal resistance of 30°C/W from junction to TAB 1, measured under standard PCB mounting conditions. This value enables accurate junction temperature estimation when power dissipation and tab temperature are known. The metallic bottom and locking tab directly enhance conduction cooling, distinguishing it from standard plastic SMD packages.
Does 1PMT5950CE3/TR13 support automated assembly processes?
Yes, the 1PMT5950CE3/TR13 is explicitly designed for compatibility with automatic insertion and SMT placement equipment. Its Powermite® package geometry, consistent marking (950), and mechanical stability - including the locking tab and unrestricted mounting orientation - meet industry requirements for high-yield automated assembly without process adaptation.
What is the maximum reverse leakage current for 1PMT5950CE3/TR13?
The maximum reverse leakage current for 1PMT5950CE3/TR13 is 4000 µA at VR = 83.6 V, as specified in the Electrical Characteristics table of MSC0995.PDF. This parameter is measured at TL = 30°C and defines the upper bound of off-state current under sub-zener bias, critical for low-power standby circuits.
Is 1PMT5950CE3/TR13 RoHS compliant?
While the original MSC0995.PDF datasheet (Rev F, 11/01/99) predates RoHS legislation, Microsemi's Powermite® family - including 1PMT5950CE3/TR13 - was later qualified to RoHS Directive 2011/65/EU. Aetrix Electronics confirms current production lots carry RoHS-compliant plating and molding compounds, with full compliance documentation available upon request.
