Product details
Overview
1PMT5953A/TR13 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. It serves as a precision voltage reference or overvoltage clamp in industrial power supplies and automotive control modules.
For engineers reviewing the 1PMT5953A/TR13 datasheet, 1PMT5953A/TR13 pinout, 1PMT5953A/TR13 application, or 1PMT5953A/TR13 equivalent, key selection criteria include its 150 V nominal Zener voltage, 3.0 W thermal capability with metallic-tab heat sinking, low 1 µA reverse leakage at 121.6 V, and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage under varying load and temperature conditions. Its Powermite® package integrates a full metallic bottom and locking tab for direct thermal conduction to PCB copper, enabling 30°C/W junction-to-TAB thermal resistance.
The device exhibits tight regulation at IZT = 2.5 mA, with knee current IZK = 0.25 mA and knee impedance ZZK = 6000 Ω, supporting low-current biasing applications while maintaining low reverse leakage (IR ≤ 1 µA at VR = 121.6 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 150 V ±5% at IZT = 2.5 mA - defines clamping threshold in overvoltage protection circuits |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-energy transient suppression without external heatsink |
| Dynamic Impedance ZZT | 600 Ω at IZT = 2.5 mA - determines voltage regulation stability under small-signal current variation |
| Reverse Leakage IR | ≤1 µA at VR = 121.6 V - ensures minimal standby power loss in high-impedance bias networks |
| Thermal Resistance | 30°C/W junction-to-TAB - allows direct thermal path to PCB ground plane for reliable 3 W operation |
| ESD Rating | >16 kV HBM - supports robust handling in automated SMT lines without additional ESD protection |
| Knee Current IZK | 0.25 mA - specifies minimum current for stable Zener conduction onset in low-power references |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5953B | Through-hole DO-41 package; same 150 V/3.0 W rating but higher thermal resistance (50°C/W) | Requires PCB footprint change and manual or wave soldering; less suitable for high-density SMT layouts | Select when legacy through-hole assembly or higher vibration tolerance is required |
| BZX84-C150 | SOT-23 package; 150 V ±5%, but rated only 300 mW and 100 Ω ZZT at 5 mA | Cannot replace 1PMT5953A/TR13 in 3.0 W applications; limited to low-power biasing | Select only for space-constrained, low-power reference use where thermal performance is secondary |
Compared with 1N5953B and BZX84-C150, the 1PMT5953A/TR13 uniquely combines 3.0 W SMT power handling, 30°C/W thermal resistance via metallic tab, and DO-216 footprint-enabling high-reliability voltage clamping without layout or process redesign.

FAQ
What is the Zener voltage tolerance for 1PMT5953A/TR13?
The 1PMT5953A/TR13 has a standard Zener voltage tolerance of ±5% at 150 V nominal, measured at IZT = 2.5 mA and TAB 1 temperature of 30°C. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available as custom order options, but the base 1PMT5953A/TR13 part uses the ±5% grade per MSC0995 Rev F specification.
How is thermal management implemented in the 1PMT5953A/TR13 package?
The 1PMT5953A/TR13 uses Microsemi's Powermite® package with a full metallic bottom and integral locking tab that serves as both mechanical anchor and primary thermal conduction path. Its specified junction-to-TAB thermal resistance is 30°C/W, meaning TAB 1 must be soldered to a thermally adequate PCB copper area to achieve the full 3.0 W power rating at 60°C tab temperature.
What is the maximum reverse leakage current for 1PMT5953A/TR13?
The maximum reverse leakage current for 1PMT5953A/TR13 is 1 µA at VR = 121.6 V, as specified in the MSC0995 datasheet Electrical Characteristics table. This value is measured at TL = 30°C and reflects the device's ability to maintain low standby current in high-impedance bias or monitoring circuits.
Is 1PMT5953A/TR13 compatible with standard SMT assembly processes?
Yes, the 1PMT5953A/TR13 is fully compatible with standard SMT assembly, including EIA-481 tape-and-reel packaging (13-inch reel, 12,000 pieces), reflow soldering profiles, and automatic insertion equipment. Its Powermite® design eliminates solder flux entrapment risk due to the full metallic bottom, enhancing long-term solder joint integrity.
What does the "TR13" suffix indicate in 1PMT5953A/TR13?
"TR13" denotes tape-and-reel packaging on a 13-inch reel containing 12,000 units, per EIA Standard 481. This is distinct from the "TR7" variant (7-inch reel, 3,000 units). The "A" in 1PMT5953A indicates the standard ±5% Zener voltage tolerance grade, differentiating it from tighter-tolerance variants like 1PMT5953C (±2%) or 1PMT5953D (±1%).
