Product details
Overview
1PMT5952CE3/TR7 from Microsemi is a 130 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 450 Ω dynamic impedance at 2.9 mA test current and thermal resistance of 30°C/W junction-to-TAB1. It serves as a precision voltage reference or overvoltage clamp in high-reliability industrial power supplies.
For engineers reviewing the 1PMT5952CE3/TR7 datasheet, 1PMT5952CE3/TR7 pinout, 1PMT5952CE3/TR7 application, or 1PMT5952CE3/TR7 equivalent, key selection criteria include its 130 V nominal Zener voltage, 3.0 W power handling in a DO-216 (Powermite®) package, low reverse leakage (<5 µA at 100 V), ESD rating >16 kV HBM, and compatibility with automated SMT assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to regulate or clamp voltage across load circuits. Its Powermite® package features a full metallic bottom and integral heat sink locking tab, enabling efficient thermal transfer to PCB copper and eliminating solder flux entrapment during reflow.
Electrical behavior is defined at TL = 30°C with Zener voltage measured 20 seconds after applying DC test current. Dynamic impedance (ZZT = 450 Ω) is derived using 60 Hz RMS AC current equal to 10% of IZT, and knee impedance (ZZK = 5000 Ω) is specified at IZK = 1 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 130 V ±5% - stable regulation point under 2.9 mA test current at 30°C case temperature |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-energy transient clamping without derating in compact layouts |
| Dynamic Impedance (ZZT) | 450 Ω at IZT = 2.9 mA - defines voltage deviation under small-signal AC load variations |
| Knee Impedance (ZZK) | 5000 Ω at IZK = 1 mA - indicates onset of stable breakdown conduction |
| Reverse Leakage (IR) | <5 µA at VR = 100 V - ensures minimal standby power loss in high-impedance bias networks |
| Thermal Resistance | 30°C/W junction-to-TAB1 - allows direct thermal path to PCB ground plane or heatsink pad |
| ESD Rating | >16 kV per Human Body Model - supports robust handling in unshielded manufacturing environments |
Pinout & Package
Package: DO-216 (Powermite®) - molded surface-mount package with full metallic bottom and integral heat sink locking tab; cathode designated by TAB 1; mounting position unrestricted; weight ≈ 0.016 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat sink interface and electrical cathode connection; must be soldered to thermal pad for rated 3.0 W operation |
| Lead 2 | Anode | Standard anode terminal; reverse-biased during Zener operation; routed away from high-noise traces |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and reflow while delivering 3.0 W power handling comparable to larger through-hole Zeners |
| Full metallic bottom | Eliminates solder flux entrapment during assembly, 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 | Reduces risk of field failure due to electrostatic discharge during board handling and system integration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5359B | Same 130 V nominal Zener voltage, but TO-204AA (DO-41) through-hole package; 5 W rating; higher thermal resistance (35°C/W) | Requires manual or wave soldering; unsuitable for high-density SMT layouts | Select when legacy through-hole design or higher continuous power margin is required |
| BZX84-C130 | 130 V Zener in SOT-23; 300 mW rating; no metallic thermal tab; 500 Ω ZZT at 5 mA | Limited to low-power signal-level clamping; cannot sustain 3.0 W transients | Select only for space-constrained logic-level protection where energy absorption is not required |
Compared with 1N5359B and BZX84-C130, the 1PMT5952CE3/TR7 uniquely combines SMT compatibility, 3.0 W power handling, and low thermal resistance in a single DO-216 package-making it the only option for high-energy, surface-mount Zener clamping in industrial power stages.

FAQ
What is the Zener voltage tolerance for 1PMT5952CE3/TR7?
The 1PMT5952CE3/TR7 has a standard Zener voltage tolerance of ±5% at 130 V nominal, as confirmed in the MSC0995.PDF datasheet. This tolerance applies under test conditions of IZT = 2.9 mA and TL = 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, but the CE3/TR7 variant uses the standard ±5% grade.
How is thermal performance characterized for 1PMT5952CE3/TR7?
The 1PMT5952CE3/TR7 has a thermal resistance of 30°C/W junction-to-TAB1, meaning each watt dissipated raises the junction temperature 30°C above the TAB1 temperature. Full 3.0 W rating requires TAB1 held at ≤60°C. The metallic bottom and locking tab enable direct thermal coupling to PCB copper, making thermal design dependent on pad size and copper area-not ambient air.
Can 1PMT5952CE3/TR7 be used in place of through-hole Zeners like 1N5359B?
No-1PMT5952CE3/TR7 is not a drop-in replacement for 1N5359B due to different packages (DO-216 vs. DO-41), thermal paths, and mounting methods. While both have 130 V Zener voltage, the 1PMT5952CE3/TR7 requires SMT reflow and relies on TAB1 thermal conduction, whereas 1N5359B uses lead-frame convection. PCB redesign is necessary for substitution.
What does the 'E3/TR7' suffix indicate in 1PMT5952CE3/TR7?
The 'E3' denotes tape-and-reel packaging per EIA-481 standard, and 'TR7' specifies a 7-inch reel containing 3,000 units. This matches the packaging details in MSC0995.PDF, which states "Tape & Reel EIA Standard 481" and lists "7 inch 3,000 pieces" for the Powermite® Zener series including 1PMT5952B.
Is 1PMT5952CE3/TR7 suitable for automotive applications?
The 1PMT5952CE3/TR7 is qualified for junction temperatures from –55°C to +150°C and has >16 kV HBM ESD rating, meeting baseline environmental robustness for many automotive subsystems. However, it is not AEC-Q200 qualified, and Microsemi's documentation does not list automotive-specific qualification-so use requires customer-level validation per ISO/TS 16949 requirements.
