Product details
Overview
1PMT5930A/TR13 from Microsemi is a 16 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 10 Ω dynamic impedance at 23.4 mA test current and thermal resistance of 30°C/W junction-to-TAB. It serves as a precision voltage reference or overvoltage clamp in DC power rails and regulator feedback paths.
For engineers reviewing the 1PMT5930A/TR13 datasheet, 1PMT5930A/TR13 pinout, 1PMT5930A/TR13 application, or 1PMT5930A/TR13 equivalent, key selection criteria include Zener voltage tolerance, power derating above 60°C, knee current (0.25 mA), reverse leakage (<1 µA at 12.2 V), and ESD robustness (>16 kV HBM).
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load or line conditions. Its DO-216 package features a full metallic bottom and integral heat sink locking tab, enabling efficient thermal transfer to the PCB pad and eliminating solder flux entrapment during reflow.
The device exhibits low reverse leakage (≤1 µA at VR = 12.2 V), tight dynamic impedance (10 Ω at IZT = 23.4 mA), and specified knee behavior (IZK = 0.25 mA, ZZK = 600 Ω), supporting reliable regulation even near minimum operating current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16 V ±5% at IZT = 23.4 mA, TL = 30°C - defines nominal regulation point with predictable deviation under standard test conditions. |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - maximum steady-state power the device can safely dissipate when mounted on a thermally adequate pad. |
| Dynamic Impedance | 10 Ω at IZT - indicates small-signal AC resistance; lower value enables tighter voltage regulation under varying load current. |
| Knee Current | 0.25 mA - minimum current at which Zener conduction becomes stable; critical for low-power biasing applications. |
| Reverse Leakage | ≤1 µA at VR = 12.2 V - ensures minimal parasitic current draw in standby or high-impedance sensing nodes. |
| Thermal Resistance | 30°C/W junction-to-TAB - quantifies temperature rise per watt; used to calculate junction temperature rise above PCB pad temperature. |
| ESD Rating | >16 kV per Human Body Model - supports handling and assembly without special ESD controls beyond standard practices. |
Pinout & Package
Package: Powermite® (DO-216), molded surface-mount package with full metallic bottom and integral heat sink locking tab; cathode designated by TAB 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat path and electrical cathode connection; must be soldered to copper pour for thermal and electrical performance. |
| Lead 2 | Anode | Standard anode terminal; connects to circuit ground or lower-potential node in Zener shunt configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and reflow assembly while delivering 3.0 W power handling in footprint comparable to smaller discrete packages. |
| Full metallic bottom | Eliminates solder flux entrapment risk during reflow, improving long-term reliability and reducing post-assembly cleaning requirements. |
| Integral heat sink locking tab | Provides mechanical anchoring and direct thermal conduction path from junction to PCB, lowering effective thermal resistance. |
| ESD robustness | >16 kV HBM rating reduces susceptibility to damage during board handling, test, and system integration without added protection circuitry. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4744A | Through-hole DO-41, 14 V, 1 W, 20 Ω Zzt - lower power, higher impedance, no metallic thermal path. | Suitable only for low-power signal-level references; cannot replace 1PMT5930A/TR13 in 3 W clamping roles. | Select only if board space allows through-hole mounting and thermal budget permits <1 W dissipation. |
| BZX84-C16 | SOT-23, 16 V, 300 mW, 40 Ω Zzt - same voltage but 1/10th power rating and higher impedance. | Limited to biasing and low-current references; insufficient for rail clamping or regulator feedback under load. | Choose only for space-constrained low-power designs where thermal management is passive and peak currents are <5 mA. |
Compared with 1N4744A and BZX84-C16, the 1PMT5930A/TR13 delivers 3× higher power handling, 4× lower dynamic impedance, and integrated thermal conduction-making it uniquely suitable for automotive and industrial power rail stabilization where sustained 23.4 mA operation and PCB-level heat sinking are required.

FAQ
What is the Zener voltage tolerance for 1PMT5930A/TR13?
The 1PMT5930A/TR13 has a nominal Zener voltage of 16 V with a standard tolerance of ±5%, measured at IZT = 23.4 mA and TAB temperature of 30°C. Tighter tolerances (±2% and ±1%) are available as suffix C and D variants, but the /TR13 marking confirms the standard ±5% version.
Can 1PMT5930A/TR13 be used in place of a 1N4744A in a 14 V reference circuit?
No - the 1PMT5930A/TR13 is rated for 16 V, not 14 V, and its 3.0 W power rating and thermal design differ significantly from the 1 W, DO-41 1N4744A. Substituting it would shift the regulation point and require PCB layout changes to accommodate the Powermite® package and thermal pad.
What is the maximum reverse leakage current for 1PMT5930A/TR13 at 12.2 V?
The maximum reverse leakage current for 1PMT5930A/TR13 is 1 µA at VR = 12.2 V and TL = 30°C. This value is specified in the Electrical Characteristics table and reflects worst-case leakage under defined test conditions, supporting low-power biasing applications.
Does 1PMT5930A/TR13 require a specific PCB pad layout for thermal performance?
Yes - the 1PMT5930A/TR13 relies on TAB 1 as its primary thermal path. A minimum 10 mm² copper pour connected to TAB 1 via multiple thermal vias is recommended to maintain junction temperature within limits at full 3.0 W dissipation. The datasheet specifies thermal resistance as 30°C/W junction-to-TAB, making pad design critical.
Is 1PMT5930A/TR13 compatible with lead-free reflow profiles?
Yes - the Powermite® package and molding compound of 1PMT5930A/TR13 are qualified for standard JEDEC J-STD-020 lead-free reflow profiles, including peak temperatures up to 260°C. The full metallic bottom also improves wetting and reduces voiding risk during Pb-free soldering.
