Product details
Overview
1PMT5925E3/TR7 from Microsemi is a 10 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 4.5 mA test current (IZT), 500 µA max reverse leakage at 5 V, and thermal resistance of 30°C/W junction-to-TAB1 - used for precision voltage regulation in compact DC power supplies and overvoltage protection circuits.
For engineers reviewing the 1PMT5925E3/TR7 datasheet, 1PMT5925E3/TR7 pinout, 1PMT5925E3/TR7 application, or 1PMT5925E3/TR7 equivalent, key selection criteria include Zener voltage tolerance, dynamic impedance (4.5 Ω), knee current (0.25 mA), ESD rating (>16 kV HBM), and thermal performance under PCB-mounted conduction cooling.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage across load variations. Its Powermite® package features a full metallic bottom for flux-free soldering and an integral locking tab acting as both mechanical anchor and heat sink, enabling reliable thermal transfer to the PCB pad.
The device exhibits low dynamic impedance (4.5 Ω at IZT = 4.5 mA) and tight knee characteristics (IZK = 0.25 mA, ZZK = 500 Ω), supporting stable regulation even at low bias currents. Reverse leakage remains ≤500 µA at VR = 5 V, ensuring minimal standby power loss in battery-sensitive designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10 V ±5% at IZT = 4.5 mA, TL = 30°C - defines primary regulation setpoint with predictable deviation across temperature and current. |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-power regulation without external heatsink when mounted on adequate copper area. |
| Dynamic Impedance | 4.5 Ω at IZT - ensures minimal output voltage shift under load transients (e.g., <45 mV for 10 mA step). |
| Knee Current | 0.25 mA - allows functional regulation down to ultra-low bias conditions, critical for low-power sensor references. |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies thermal path efficiency; requires ≥100 mm² 2-oz copper pad for full 3 W operation. |
| ESD Rating | >16 kV per HBM - eliminates need for external ESD protection in handling and board-level integration. |
Pinout & Package
Package: Powermite® surface-mount molded package with full metallic bottom and integral locking tab; cathode designated by TAB 1; weight ≈ 0.016 g; mounting position unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal and electrical cathode connection; must be soldered to PCB thermal pad for rated power handling. |
| Lead 2 | Anode | Standard anode connection; reverse-biased during Zener operation; no thermal function. |
Key Features
| Feature | Design Value |
|---|---|
| Integral heat sink locking tab | Mechanically anchors device while conducting heat directly from junction to PCB via TAB 1 - eliminates need for secondary thermal vias or paste. |
| Full metallic bottom | Prevents solder flux entrapment during reflow, reducing risk of post-assembly corrosion or voiding in high-reliability assemblies. |
| Automated insertion compatibility | Robust mechanical design supports high-speed pick-and-place without damage or misalignment - validated for EIA-481 tape & reel (7″/3,000 pcs). |
| Low knee impedance | ZZK = 500 Ω at IZK = 0.25 mA - maintains regulation stability even when operating near minimum bias current. |
Applications
| Industrial Power Supply Regulation | Automotive Body Control Module Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5925B | Same 10 V, ±5%, 3.0 W rating but in DO-41 axial package; higher thermal resistance (~65°C/W); no metallic bottom or locking tab. | Requires through-hole mounting and external heatsinking for equivalent power handling; unsuitable for automated SMT lines. | Select only if legacy through-hole design or manual assembly is required; not drop-in compatible with 1PMT5925E3/TR7 footprint. |
| BZX84-C10 | 10 V, ±5%, but rated for 300 mW only; SOT-23 package; dynamic impedance ~20 Ω; no specified ESD rating. | Limited to low-power signal conditioning; cannot replace 1PMT5925E3/TR7 in 3 W regulation or transient clamping roles. | Use only in space-constrained, sub-100 mW bias applications where thermal performance is non-critical. |
Compared with 1N5925B and BZX84-C10, the 1PMT5925E3/TR7 uniquely combines SMT manufacturability, 3 W power capability, and integrated thermal management - making it the sole option for high-reliability, high-power Zener regulation in automated production.

FAQ
What is the Zener voltage tolerance for 1PMT5925E3/TR7?
The 1PMT5925E3/TR7 has a standard Zener voltage tolerance of ±5% at 10 V, measured at IZT = 4.5 mA and TAB 1 temperature of 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D, respectively, but are not applicable to the E3/TR7 variant.
How is thermal management handled in the 1PMT5925E3/TR7 package?
The 1PMT5925E3/TR7 uses its metallic TAB 1 as the primary thermal path, with a specified junction-to-TAB thermal resistance of 30°C/W. Effective cooling requires soldering TAB 1 to a minimum 100 mm² copper area on the PCB; no additional heatsink or thermal compound is needed for full 3.0 W operation at TAB 1 ≤ 60°C.
Is the 1PMT5925E3/TR7 suitable for automated SMT assembly?
Yes, the 1PMT5925E3/TR7 is fully compatible with automated insertion equipment and supplied in EIA-481 tape-and-reel format (7-inch reel, 3,000 pieces). Its Powermite® package includes a locking tab and full metallic bottom to prevent misalignment and flux entrapment during reflow soldering.
What is the maximum reverse leakage current for 1PMT5925E3/TR7?
The 1PMT5925E3/TR7 specifies a maximum reverse leakage current (IR) of 500 µA at VR = 5 V and TL = 30°C. This low leakage supports energy-efficient operation in battery-powered systems and minimizes error in precision reference applications.
Does the 1PMT5925E3/TR7 have ESD protection built in?
Yes, the 1PMT5925E3/TR7 has an ESD rating exceeding 16 kV per the Human Body Model (HBM), as confirmed in the MSC0995 datasheet. This eliminates the need for external ESD protection components during handling or board-level integration in typical industrial environments.
