Product details
Overview
1PMT5953CE3/TR7 from Microsemi is a 150 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 600 Ω dynamic impedance at 2.5 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 1PMT5953CE3/TR7 datasheet, 1PMT5953CE3/TR7 pinout, 1PMT5953CE3/TR7 application, or 1PMT5953CE3/TR7 equivalent, key selection criteria include zener voltage tolerance, thermal resistance (30°C/W junction-to-TAB), reverse leakage (<6000 µA at 120 V), knee current (0.25 mA), and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This Zener diode operates as a two-terminal voltage reference device with cathode designated by TAB 1. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and eliminate solder flux entrapment during reflow.
Electrical behavior is defined at TL = 30°C with VZ measured 20 seconds after DC current application; dynamic impedance (ZZT) is derived using 60 Hz RMS AC current equal to 10% of IZT, and voltage regulation remains stable across -55°C to +150°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 150 V ±5% - precise clamping threshold for overvoltage protection circuits |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-energy transient suppression without heatsink |
| Dynamic Impedance | 600 Ω at IZT = 2.5 mA - ensures stable regulation under small-signal load variations |
| Knee Current | 0.25 mA - defines minimum current for reliable Zener conduction onset |
| Thermal Resistance | 30°C/W junction-to-TAB - supports thermal management via PCB copper pour on TAB 1 |
| ESD Rating | >16 kV HBM - provides robust handling immunity in automated SMT lines |
| Reverse Leakage | <6000 µA at VR = 120 V - guarantees low standby power loss in bias networks |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5375B | Same 150 V nominal, but DO-204AL (DO-41) through-hole package; 3.0 W rating at 75°C ambient; no metallic bottom or locking tab | Requires manual or wave soldering; unsuitable for high-density SMT layouts | Select only when legacy through-hole assembly is mandated and thermal performance margin is ≥15°C |
| BZX84-C150 | SOT-23 package; 150 V ±5%; 300 mW power rating; 1000 Ω ZZT at 5 mA; no specified HBM rating | Limited to low-power biasing; cannot sustain 3.0 W surge clamping | Use only in space-constrained low-energy circuits where thermal mass is externally managed |
Compared with 1N5375B and BZX84-C150, the 1PMT5953CE3/TR7 delivers superior thermal performance (30°C/W vs >60°C/W), automated assembly readiness (EIA-481 tape/reel), and ruggedized handling (16 kV HBM), making it the sole choice for industrial-grade SMT power regulation requiring sustained 3.0 W dissipation.

FAQ
What is the maximum power dissipation rating for 1PMT5953CE3/TR7?
The 1PMT5953CE3/TR7 is rated for 3.0 W DC power dissipation when TAB 1 is maintained at 60°C. This rating assumes proper thermal coupling to PCB copper; derating is required above 60°C ambient per the 30°C/W junction-to-TAB thermal resistance. The 1PMT5953CE3/TR7 achieves this dissipation without external heatsinking due to its integral locking tab and full metallic bottom design.
How is the cathode identified on 1PMT5953CE3/TR7?
The cathode of the 1PMT5953CE3/TR7 is designated by TAB 1, which serves as both the electrical cathode terminal and primary thermal path. This is confirmed in the mechanical specifications section of the MSC0995.PDF datasheet. Correct orientation is essential: TAB 1 must be connected to the lower-potential node in the circuit to enable proper Zener breakdown operation of the 1PMT5953CE3/TR7.
What does the 'E3/TR7' suffix indicate in 1PMT5953CE3/TR7?
The 'E3' denotes compliance with JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3), and 'TR7' specifies packaging in 7-inch tape-and-reel per EIA-481 standard containing 3,000 units. This confirms the 1PMT5953CE3/TR7 is qualified for standard SMT reflow processes and supports high-volume automated placement - a requirement explicitly validated in Microsemi's packaging documentation for the 1PMT5953CE3/TR7.
What is the reverse leakage current specification for 1PMT5953CE3/TR7 at 120 V?
Per the Electrical Characteristics table in MSC0995.PDF, the 1PMT5953CE3/TR7 has a maximum reverse leakage current (IR) of 6000 µA at VR = 120 V. This value is measured under standard test conditions (TL = 30°C) and defines the upper bound of standby current draw when the 1PMT5953CE3/TR7 is used in bias or reference networks operating below its 150 V Zener voltage.
Is 1PMT5953CE3/TR7 suitable for use in automotive applications?
Yes, the 1PMT5953CE3/TR7 is suitable for automotive applications including ECU power rail protection, provided ambient temperature and PCB thermal design meet its -55°C to +150°C junction temperature range. Its 16 kV HBM ESD rating, 3.0 W power capability, and robust Powermite® package make the 1PMT5953CE3/TR7 appropriate for under-hood and body-control module designs per AEC-Q101 stress-test guidelines.
