Product details
Overview
1PMT5925CE3/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-TAB. It serves as a precision voltage reference or overvoltage clamp in DC power rails and analog signal conditioning circuits.
For engineers reviewing the 1PMT5925CE3/TR7 datasheet, 1PMT5925CE3/TR7 pinout, 1PMT5925CE3/TR7 application, or 1PMT5925CE3/TR7 equivalent, key selection criteria include zener voltage tolerance (±5%), low knee impedance (500 Ω), ESD robustness (>16 kV HBM), thermal performance (30°C/W), and compatibility with automated SMT assembly per EIA-481 tape-and-reel packaging.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage regulation across varying load currents. Its Powermite® package integrates a full metallic bottom and locking tab for enhanced thermal conduction and mechanical stability during reflow soldering.
The device exhibits tight dynamic impedance (ZZT = 4.5 Ω at IZT = 37.5 mA) and low knee impedance (ZZK = 500 Ω at IZK = 0.25 mA), enabling effective regulation even near minimum operating current. Reverse leakage remains ≤500 µA at VR = 5 V, supporting low-power standby functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10 V ±5% at IZT = 37.5 mA - defines nominal regulation point with predictable deviation under production conditions |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - maximum continuous DC power handling with defined thermal boundary condition |
| Dynamic Impedance | 4.5 Ω at IZT - low AC impedance ensures minimal output voltage variation under dynamic load changes |
| Knee Impedance | 500 Ω at IZK = 0.25 mA - characterizes regulation onset behavior near turn-on threshold |
| Reverse Leakage | ≤500 µA at VR = 5 V - enables low-quiescent-current operation in battery-backed or energy-sensitive designs |
| ESD Rating | >16 kV HBM - provides robust protection against electrostatic discharge during handling and board assembly |
| Thermal Resistance | 30°C/W junction-to-TAB - quantifies thermal path efficiency for heatsinking via PCB copper or metal-core substrate |
Pinout & Package
Package: Powermite® (DO-216AA), molded surface-mount package with full metallic bottom and integral heat-sink locking tab. Cathode is designated by TAB 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-dissipating terminal; must be connected to thermal pad or copper pour for rated 3.0 W operation |
| Lead 2 | Anode | Standard anode connection; polarity confirmed by cathode marking on package body |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables high-density PCB layouts while delivering 3.0 W power handling comparable to larger through-hole Zeners |
| Integral heat-sink locking tab | Provides mechanical anchoring during reflow and direct thermal conduction path from junction to PCB |
| Full metallic bottom | Eliminates solder flux entrapment risk and improves thermal transfer versus plastic-bottom SMD packages |
| ESD robustness >16 kV HBM | Reduces need for external ESD protection in front-end power and interface circuits |
| Compatible with EIA-481 tape & reel | Supports high-speed pick-and-place assembly without manual handling or orientation concerns |
Applications
| DC Power Rail Regulation | Overvoltage Protection Clamp |
|---|---|
Use Scenario: Stabilizing 12 V supply rail for microcontroller I/O peripherals in industrial control modules. IC Role / Device Role / Timing Role: Zener diode acting as shunt voltage regulator, clamping rail voltage to 10 V when input exceeds regulation threshold. Use Value: Maintains safe logic-level compliance using only passive components, with thermal stability ensured by TAB 1 copper connection. | Use Scenario: Protecting ADC reference input from transient surges in automotive sensor interfaces. IC Role / Device Role / Timing Role: Fast-acting overvoltage clamp limiting input to 10 V ±5%, preventing damage to sensitive analog inputs. Use Value: Leverages low ZZK (500 Ω) to respond rapidly at low current, minimizing voltage overshoot during ESD events. |

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 rating and ±5% tolerance, but in DO-41 through-hole package; no metallic bottom or locking tab; 1.5 W rating | Requires PCB hole drilling and wave soldering; unsuitable for high-density SMT layouts or thermal-intensive 3 W operation | Select 1N5925B only for legacy through-hole designs where rework flexibility or lower cost outweighs power/thermal needs |
| BZX84-C10 | 10 V ±5%, SOT-23 package; 300 mW power rating; higher ZZT (~20 Ω); no specified HBM ESD rating | Limited to low-power signal conditioning; cannot sustain 3.0 W dissipation or meet >16 kV ESD requirements | Choose BZX84-C10 for space-constrained signal-level clamping where full 3 W capability is unnecessary |
Compared with 1N5925B and BZX84-C10, the 1PMT5925CE3/TR7 uniquely combines 3.0 W SMT power handling, integrated thermal management via TAB 1, and >16 kV ESD immunity-making it the only option among the three suitable for ruggedized industrial power rail stabilization.

FAQ
What is the zener voltage tolerance for 1PMT5925CE3/TR7?
The 1PMT5925CE3/TR7 has a standard zener voltage tolerance of ±5% at 10 V, measured at IZT = 37.5 mA with TAB 1 held at 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, but the CE3/TR7 variant specifies ±5%. This tolerance directly impacts regulation accuracy in precision reference applications.
How is thermal management handled in the 1PMT5925CE3/TR7 package?
The 1PMT5925CE3/TR7 uses the Powermite® package with a full metallic bottom and integral locking tab that serves as the primary thermal path. Its specified thermal resistance is 30°C/W junction-to-TAB 1, meaning effective heatsinking requires direct connection of TAB 1 to a large copper area or thermal pad on the PCB to sustain the full 3.0 W rating.
Is 1PMT5925CE3/TR7 compatible with automated SMT assembly processes?
Yes, the 1PMT5925CE3/TR7 is supplied in EIA-481 compliant tape-and-reel format (7-inch reel, 3,000 pieces) and features a symmetric, self-aligning Powermite® footprint designed for reliable pick-and-place placement. Its locking tab and full metallic bottom also prevent tombstoning and improve solder joint integrity during reflow.
What is the maximum reverse leakage current for 1PMT5925CE3/TR7?
The maximum reverse leakage current for 1PMT5925CE3/TR7 is 500 µA at VR = 5 V and TL = 30°C. This low leakage supports energy-efficient operation in always-on circuits and ensures minimal loading on upstream regulators or battery sources in portable equipment.
Does 1PMT5925CE3/TR7 meet industry-standard ESD requirements?
Yes, the 1PMT5925CE3/TR7 is rated for >16 kV per Human Body Model (HBM), exceeding typical IEC 61000-4-2 Level 4 (8 kV contact) requirements. This high ESD immunity reduces susceptibility to damage during handling, assembly, and field operation-critical for industrial and automotive applications.
