Product details
Overview
1PMT5952BE3/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 - used for precision voltage regulation and overvoltage protection in industrial power supplies.
For engineers reviewing the 1PMT5952BE3/TR7 datasheet, 1PMT5952BE3/TR7 pinout, 1PMT5952BE3/TR7 application, or 1PMT5952BE3/TR7 equivalent, key selection criteria include zener voltage accuracy, power derating at elevated tab temperature, ESD robustness (>16 kV HBM), low reverse leakage (≤1 µA at 100 V), and compatibility with automated SMT assembly per EIA-481 tape-and-reel packaging.
Technical Context
This device operates as a voltage-reference and clamping element in DC power rails, where its 130 V nominal zener voltage stabilizes against load and line variations. Its full metallic bottom and integral locking tab enable direct thermal coupling to PCB copper, supporting reliable 3.0 W power handling without external heatsinking when mounted on ≥1 sq-in 2-oz copper.
The 1PMT5952BE3/TR7 exhibits tight knee characteristics (IZK = 0.25 mA, ZZK = 5000 Ω) and low reverse leakage (IR ≤ 1 µA at VR = 100 V), enabling stable regulation even under light-load conditions typical in standby circuits and sensing interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 130 V ±5% at IZT = 2.9 mA - defines precise clamping threshold for overvoltage protection circuits |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-energy transient suppression without forced cooling |
| Dynamic Impedance (ZZT) | 450 Ω at IZT = 2.9 mA - determines output voltage variation under load current changes |
| Thermal Resistance | 30°C/W junction-to-TAB1 - allows accurate thermal design using PCB copper area as heatsink |
| ESD Rating | >16 kV per Human Body Model - ensures robustness during automated handling and board assembly |
| Reverse Leakage (IR) | ≤1 µA at VR = 100 V - minimizes standby power loss in high-impedance bias networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ130A | TVS diode (not Zener); 130 V standoff, 200 W peak pulse power, higher clamping voltage (179 V) | Designed for transient suppression only; not suitable for precision regulation or low-current biasing | Select only for surge-only protection where regulation accuracy is irrelevant |
| 1N5375B | Through-hole 130 V Zener; 5 W rating but requires TO-204AA package and heatsinking; no SMT compatibility | Not compatible with automated SMT lines; higher thermal resistance (50°C/W) limits PCB-area-constrained designs | Choose only for legacy through-hole designs or where >3 W continuous dissipation is mandatory |
Compared with SMCJ130A and 1N5375B, the 1PMT5952BE3/TR7 uniquely combines SMT manufacturability, 3.0 W continuous regulation capability, and ±5% voltage accuracy in a thermally optimized surface-mount package - making it optimal for space-constrained, high-reliability power rail stabilization.

FAQ
What is the zener voltage tolerance for 1PMT5952BE3/TR7?
The 1PMT5952BE3/TR7 has a standard zener voltage tolerance of ±5% at 130 V, measured at IZT = 2.9 mA and TAB 1 temperature of 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D respectively, but the E3/TR7 variant is specified at ±5%.
Can 1PMT5952BE3/TR7 be used in reflow soldering processes?
Yes, the 1PMT5952BE3/TR7 is qualified for standard lead-free reflow soldering per J-STD-020. Its Powermite® package features a full metallic bottom that resists flux entrapment, and its molding compound withstands peak temperatures up to 260°C - ensuring reliability in automated SMT assembly lines.
What is the maximum reverse leakage current for 1PMT5952BE3/TR7?
The maximum reverse leakage current for 1PMT5952BE3/TR7 is 1 µA at VR = 100 V and TL = 30°C. This low leakage supports energy-efficient operation in always-on circuits such as automotive BCM wake-up monitors and telecom standby rails.
How is thermal performance defined for 1PMT5952BE3/TR7?
Thermal performance for 1PMT5952BE3/TR7 is defined by a junction-to-TAB1 thermal resistance of 30°C/W. Full 3.0 W power dissipation is rated at TAB 1 = 60°C; derating is linear to zero at 150°C junction temperature, requiring appropriate PCB copper area for heat spreading.
Is 1PMT5952BE3/TR7 suitable for surge protection applications?
The 1PMT5952BE3/TR7 is designed for precision voltage regulation and steady-state clamping, not high-energy transient suppression. While it can absorb limited surge energy, dedicated TVS diodes like SMCJ130A are preferred for lightning or ESD surge events due to higher peak power ratings and faster response.
