Product details
Overview
1PMT5925AE3/TR13 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), 450 Ω dynamic impedance (ZZT), and 8.0 mA maximum Zener current (IZM). It serves as a precision voltage reference or overvoltage clamp in DC power rails and regulator feedback paths.
For engineers reviewing the 1PMT5925AE3/TR13 datasheet, 1PMT5925AE3/TR13 pinout, 1PMT5925AE3/TR13 application, or 1PMT5925AE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (30°C/W junction-to-TAB1), ESD rating (>16 kV HBM), reverse leakage (<500 µA at VR = 5 V), and compatibility with automated SMT assembly per EIA-481 tape-and-reel packaging.
Technical Context
This device operates as a two-terminal voltage-regulating element with cathode designated by TAB 1. Its Powermite® package integrates a full metallic bottom for flux-free soldering and a locking tab acting as an integral heat sink, enabling reliable thermal transfer to the PCB copper pour.
Electrical behavior is defined at TL = 30°C with IZT = 4.5 mA; voltage measurement must occur within 20 seconds of DC current application. Dynamic impedance (ZZT = 450 Ω) is measured using 60 Hz RMS AC current equal to 10% of IZT superimposed on IZT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10 V ±5% - stable reference voltage at IZT = 4.5 mA, suitable for ±0.5 V regulation tolerance in feedback networks |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables high-power clamping without external heatsink when mounted on ≥1 sq-in copper area |
| Dynamic Impedance (ZZT) | 450 Ω - limits output voltage variation under load transients; critical for low-noise reference stability |
| Thermal Resistance | 30°C/W junction-to-TAB1 - defines temperature rise per watt; requires thermal pad design for sustained 3 W operation |
| ESD Rating | >16 kV HBM - protects against handling-induced discharge without external TVS in board-level ESD zones |
| Reverse Leakage (IR) | <500 µA at VR = 5 V - ensures minimal quiescent current in standby-mode voltage monitors |
| Knee Current (IZK) | 0.25 mA - minimum current needed to enter regulated region; supports low-power biasing applications |
Pinout & Package
Package: Powermite® (DO-216AA), molded surface-mount package with full metallic bottom and integral locking tab heat sink. Cathode is designated by TAB 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal; must be connected to large copper area for thermal management and electrical return path |
| Lead 2 | Anode | Signal-side connection; routed with controlled trace width to minimize IR drop in precision reference paths |
Key Features
| Feature | Design Value |
|---|---|
| Full metallic bottom | Eliminates solder flux entrapment during reflow, reducing post-assembly cleaning requirements and void risk |
| Integral heat sink locking tab | Provides mechanical anchoring and direct thermal conduction path from junction to PCB, lowering effective θJA |
| ESD robustness | >16 kV HBM rating allows safe handling and integration into unshielded industrial control I/O stages |
| Tape-and-reel packaging | EIA-481 compliant 13-inch reel (12,000 pcs) supports high-speed pick-and-place without component damage or orientation error |
Applications
| DC Power Rail Clamping | Feedback Reference in SMPS |
|---|---|
Use Scenario: Protecting 12 V automotive ECUs from load-dump transients up to 40 V. IC Role / Device Role / Timing Role: Zener clamping element placed between rail and ground, conducting only above 10 V threshold. Use Value: Limits peak voltage to 10.5 V (±5%) with 3 W surge capability, avoiding need for higher-cost TVS diodes. | Use Scenario: Providing stable 10 V reference for optocoupler feedback in isolated flyback converters. IC Role / Device Role / Timing Role: Voltage reference node in secondary-side error amplifier circuit. Use Value: Tight 5% tolerance and low ZZT ensure <±1% output regulation across line/load variations. |

Use Value: Fast turn-on at IZK = 0.25 mA enables detection within 10 µs of overvoltage onset. |
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 W rating but in DO-41 through-hole package; no metallic bottom or locking tab | Requires manual or wave soldering; unsuitable for high-density SMT layouts | Select 1N5925B only if legacy through-hole assembly or thermal constraints allow larger footprint |
| BZX84-C10 | 10 V, ±5%, 300 mW SOT-23 package; 10× lower power rating and 600 Ω typical ZZT | Limited to low-current references (<20 mA); not viable for clamping >100 mA surges | Choose BZX84-C10 only for space-constrained, low-power signal conditioning-not for power rail protection |
Compared with 1N5925B and BZX84-C10, the 1PMT5925AE3/TR13 uniquely delivers 3 W SMT power handling with integrated thermal management-enabling compact, high-reliability clamping where board space and thermal performance are co-constrained.

FAQ
What is the Zener voltage tolerance for 1PMT5925AE3/TR13?
The 1PMT5925AE3/TR13 has a nominal Zener voltage of 10 V with a standard tolerance of ±5%, meaning the actual VZ falls between 9.5 V and 10.5 V when measured at IZT = 4.5 mA and TAB 1 temperature = 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, but the E3/TR13 variant uses the standard ±5% grade.
How is thermal management handled in the 1PMT5925AE3/TR13 package?
The 1PMT5925AE3/TR13 uses the Powermite® package with a full metallic bottom and integral locking tab that acts as a heat sink. Its specified thermal resistance is 30°C/W junction-to-TAB1, so effective cooling requires connecting TAB 1 to a substantial copper area (≥1 square inch) on the PCB. This design eliminates flux entrapment and enables direct thermal conduction without additional hardware.
Can 1PMT5925AE3/TR13 be used in automated SMT assembly lines?
Yes, the 1PMT5925AE3/TR13 is fully compatible with automated insertion equipment and supplied in EIA-481 standard tape-and-reel format (13-inch reel, 12,000 pieces). Its molded Powermite® package features consistent dimensions and a locking tab that prevents rotation during pick-and-place, ensuring high placement yield and repeatable solder joint formation.
What is the maximum reverse leakage current for 1PMT5925AE3/TR13 at 5 V?
At VR = 5 V and TL = 30°C, the maximum reverse leakage current (IR) for the 1PMT5925AE3/TR13 is 500 µA. This value is confirmed in the manufacturer's electrical characteristics table and reflects worst-case leakage under specified test conditions-critical for low-power applications where standby current must remain below 1 µA budgets.
Does 1PMT5925AE3/TR13 meet industry ESD standards?
Yes, the 1PMT5925AE3/TR13 is rated for >16 kV per Human Body Model (HBM), exceeding IEC 61000-4-2 Level 4 (8 kV contact / 15 kV air) requirements. This intrinsic ESD robustness eliminates the need for external protection in many industrial I/O and sensor interface designs, simplifying layout and improving system-level reliability without adding discrete TVS components.
