Product details
Overview
1PMT5952A/TR13 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 power supply feedback loops.
For engineers reviewing the 1PMT5952A/TR13 datasheet, 1PMT5952A/TR13 pinout, 1PMT5952A/TR13 application, or 1PMT5952A/TR13 equivalent, key selection criteria include zener voltage stability under thermal stress, low reverse leakage (<1 µA at 100 V), ESD robustness (>16 kV HBM), and compatibility with automated SMT assembly using EIA-481 tape-and-reel packaging.
Technical Context
This device operates as a two-terminal voltage-regulating diode with cathode designated by TAB 1. Its Powermite® package integrates a full metallic bottom to prevent solder flux entrapment and locking tabs that act as integral heat sinks-enabling reliable thermal transfer without external heatsinking in space-constrained layouts.
Electrical behavior is defined at TL = 30°C with zener voltage measured 20 seconds after applying DC test current; dynamic impedance is derived using 60 Hz RMS AC current equal to 10% of IZT. The 130 V nominal zener voltage supports high-voltage rail monitoring and transient suppression in industrial DC-DC converters and telecom power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 130 V ±5% at IZT = 2.9 mA - sets precise clamping threshold for 120–140 V system protection |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables sustained operation in thermally demanding environments without derating |
| Dynamic Impedance (ZZT) | 450 Ω at IZT = 2.9 mA - ensures stable regulation under small-signal load variations |
| Thermal Resistance | 30°C/W junction-to-TAB1 - allows direct thermal path to PCB copper pour or chassis for passive cooling |
| ESD Rating | >16 kV per Human Body Model - provides robust handling and board-level ESD immunity without added protection circuitry |
| Reverse Leakage | <1 µA at VR = 100 V - minimizes standby power loss in high-impedance bias networks |
| Knee Current (IZK) | 0.25 mA - defines minimum current required to enter regulated region, critical for low-power sensing circuits |
Pinout & Package
The 1PMT5952A/TR13 uses a DO-216 molded surface-mount package with a full metallic bottom and integral heat-sink locking tabs. Cathode is unambiguously designated by TAB 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary thermal and electrical connection point; must be soldered to large copper area for thermal management |
| Other Terminal | Anode | Standard anode connection; no polarity marking other than TAB 1 designation |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and reflow while delivering 3.0 W power handling in footprint smaller than DO-41 |
| Full metallic bottom | Eliminates solder flux entrapment during reflow, improving long-term solder joint reliability and process yield |
| Integral heat-sink locking tabs | Provides mechanical anchoring and direct thermal conduction path from junction to PCB, reducing thermal resistance by ~40% vs. standard SOD packages |
| ESD robustness >16 kV HBM | Reduces need for external ESD protection in front-end power rails and interface circuits |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5355B | Same 130 V nominal, but DO-15 package (larger, axial lead); 3.0 W rating; higher ZZT = 500 Ω | Requires through-hole assembly; less suitable for high-density SMT layouts | Select when legacy through-hole design or higher surge current capability is prioritized over size and thermal performance |
| BZX84-C130 | SOT-23 package; 130 V ±5%; lower power (500 mW); ZZT = 500 Ω; no metallic heat sink | Limited to low-power signal conditioning; cannot sustain 3.0 W continuous dissipation | Select only for bias/reference use in low-current circuits where thermal load is negligible |
Compared with 1N5355B and BZX84-C130, the 1PMT5952A/TR13 uniquely delivers 3.0 W power handling in a surface-mount DO-216 package with integrated thermal management-making it the only option among the three capable of sustained high-voltage clamping in compact, thermally constrained industrial power designs.

FAQ
What is the zener voltage tolerance for 1PMT5952A/TR13?
The 1PMT5952A/TR13 has a standard zener voltage tolerance of ±5% at 130 V nominal, measured at IZT = 2.9 mA with TAB 1 held at 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D respectively, but the base 1PMT5952A/TR13 part carries the ±5% specification as documented in MSC0995 Rev F.
How is thermal performance characterized for 1PMT5952A/TR13?
The 1PMT5952A/TR13 has a junction-to-TAB1 thermal resistance of 30°C/W, meaning each watt of dissipated power raises the junction temperature 30°C above TAB 1 temperature. This value assumes TAB 1 is soldered to sufficient copper area; actual thermal performance depends on PCB layout and ambient conditions.
Is 1PMT5952A/TR13 compatible with standard SMT reflow processes?
Yes, the 1PMT5952A/TR13 is qualified for standard lead-free reflow profiles per J-STD-020. Its Powermite® package features a full metallic bottom that eliminates solder flux entrapment, and its mechanical construction supports automatic insertion equipment and high-yield reflow soldering without tombstoning or voiding concerns.
What does the "TR13" suffix indicate in 1PMT5952A/TR13?
The "TR13" suffix denotes tape-and-reel packaging per EIA-481 standard on a 13-inch reel containing 12,000 units. This format is optimized for high-volume automated pick-and-place assembly and aligns with industry-standard feeder compatibility requirements.
Can 1PMT5952A/TR13 be used as a replacement for older through-hole Zeners like 1N5355B?
While 1PMT5952A/TR13 matches the 130 V rating and 3.0 W power dissipation of 1N5355B, it is not a drop-in replacement due to its DO-216 surface-mount footprint versus DO-15 through-hole. Board redesign is required-but the 1PMT5952A/TR13 offers superior thermal performance, ESD rating, and automated assembly compatibility in new designs.
