Product details
Overview
1PMT5929B from Microsemi is a 15 V, 3.0 W surface-mount Zener diode in the Powermite® package, featuring a full metallic bottom, integral heat sink locking tab, and 16 kV HBM ESD rating. It delivers tight voltage regulation (±5% tolerance) with low reverse leakage (≤600 µA at 11.4 V), used for overvoltage protection and precision reference in power supplies and industrial controls.
For engineers reviewing the 1PMT5929B datasheet, 1PMT5929B pinout, 1PMT5929B application, or 1PMT5929B equivalent, key selection criteria include zener voltage (15 V), power dissipation (3.0 W), thermal resistance (30°C/W), cathode identification via TAB 1, and compatibility with EIA-481 tape-and-reel packaging.
Technical Context
This Zener diode operates as a voltage reference and clamp device with a nominal zener voltage of 15 V at 25 mA test current (IZT), dynamic impedance of 9.0 Ω, and knee current of 0.25 mA. Its thermal resistance from junction to TAB 1 is 30°C/W, enabling stable operation up to +150°C junction temperature.
The Powermite® package integrates a metallic heat-sinking tab (TAB 1 = cathode) and eliminates solder flux entrapment via full metallic bottom. It supports automated insertion and conforms to DO-216 mechanical outline with 3.0 W DC power dissipation capability when TAB 1 is held at 60°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15 V ±5% at IZT = 25 mA - defines precise clamping/reference level under standard bias |
| Power Dissipation | 3.0 W - enables robust overvoltage protection without external heatsink at TAB 1 = 60°C |
| Dynamic Impedance (ZZT) | 9.0 Ω - ensures minimal voltage deviation under small-signal AC load variations |
| Reverse Leakage (IR) | ≤600 µA at VR = 11.4 V - guarantees low standby power loss in high-impedance bias networks |
| Thermal Resistance | 30°C/W (junction to TAB 1) - allows accurate thermal design with direct tab mounting to PCB copper |
| ESD Rating | >16 kV HBM - provides inherent system-level ESD robustness without added protection circuitry |
| Knee Current (IZK) | 0.25 mA - specifies minimum current for stable zener conduction onset, critical for low-power biasing |
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 thermal pad for rated 3.0 W operation |
| Lead 2 | Anode | Standard anode terminal; electrically isolated from TAB 1; used for series connection in voltage reference chains |
Key Features
| Feature | Design Value |
|---|---|
| Integral heat sink locking tab | Direct thermal path from junction to PCB via TAB 1, reducing thermal resistance to 30°C/W |
| Full metallic bottom | Eliminates solder flux entrapment during reflow, improving long-term reliability and void-free solder joints |
| Automated insertion compatibility | DO-216 footprint and mechanical stability support high-speed pick-and-place without misalignment |
| High ESD immunity | >16 kV HBM rating reduces need for external ESD protection in board-level designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF15A (ON Semiconductor) | Same 15 V nominal, 200 W peak pulse power, but SOD-123 package; higher Zener impedance (15 Ω) | Better suited for transient suppression vs. precision regulation due to higher ZZT and different thermal profile | Select 1PMT5929B for continuous 3.0 W regulation; SMF15A for infrequent surge clamping |
| BZX84-C15 (Diodes Inc.) | SOT-23 package, 300 mW rating, ±5% tolerance, 15 Ω dynamic impedance, no metallic tab | Limited to low-power biasing; lacks thermal performance and ESD robustness of Powermite® | Choose 1PMT5929B where 3.0 W dissipation, 30°C/W thermal resistance, or >16 kV ESD are required |
Compared with SMF15A and BZX84-C15, the 1PMT5929B offers superior continuous power handling, lower dynamic impedance, and integrated thermal management-making it optimal for high-stability reference and sustained clamp applications rather than transient-only or low-power use cases.

FAQ
What is the zener voltage tolerance for 1PMT5929B?
The 1PMT5929B has a standard zener voltage tolerance of ±5% at 25 mA test current and 30°C case temperature. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available upon request. Voltage measurement must be performed 20 seconds after applying DC current to ensure thermal stabilization.
How is the cathode identified on the 1PMT5929B package?
The cathode of the 1PMT5929B is designated by TAB 1-the large metallic tab on the package bottom. This tab serves as both the cathode terminal and primary thermal path. The anode is connected to the smaller lead (Lead 2), which is electrically isolated from the tab.
What is the maximum power dissipation of 1PMT5929B and under what conditions?
The 1PMT5929B is rated for 3.0 W DC power dissipation when TAB 1 is maintained at 60°C. This rating assumes proper thermal coupling to a PCB copper area. Derating is required above 60°C tab temperature, with full derating to zero at 150°C junction temperature.
Does 1PMT5929B meet any industry-standard ESD specifications?
Yes, the 1PMT5929B is rated for >16 kV per the Human Body Model (HBM) ESD test (MIL-STD-883, Method 3015). This high immunity level is intrinsic to the Powermite® construction and does not require external ESD protection in most end-equipment designs.
Can 1PMT5929B be used in automated SMT assembly processes?
Yes, the 1PMT5929B is fully compatible with automated insertion and surface-mount assembly. Its DO-216 outline, consistent weight (0.016 g), and mechanical stability support reliable pick-and-place operations. It ships in EIA-481 compliant tape-and-reel formats (3,000 pcs/7″ reel or 12,000 pcs/13″ reel).
