Product details
Overview
1PMT5929AE3/TR13 from Microsemi is a 15 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 9.0 Ω dynamic impedance at 25 mA test current and thermal resistance of 30°C/W junction-to-TAB1 - used for precision voltage regulation and overvoltage protection in compact DC power rails.
For engineers reviewing the 1PMT5929AE3/TR13 datasheet, 1PMT5929AE3/TR13 pinout, 1PMT5929AE3/TR13 application, or 1PMT5929AE3/TR13 equivalent, key selection criteria include zener voltage tolerance, power derating above 60°C, knee current (IZK = 0.25 mA), reverse leakage (IR ≤ 1 µA at VR = 12.2 V), and ESD robustness (>16 kV HBM).
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its Powermite® package features a full metallic bottom and integral locking tab acting as a heat sink, enabling direct thermal conduction from junction to PCB copper via TAB 1.
Designed for automatic insertion and reflow assembly, it complies with EIA-481 tape-and-reel packaging (13-inch reel, 12,000 pcs). Cathode is unambiguously designated by TAB 1, and mechanical mounting orientation is unrestricted due to symmetrical molded construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15 V ±5% at IZT = 25 mA, TL = 30°C - defines nominal regulation point with predictable deviation across production lot |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous DC power before thermal runaway; derates linearly above 60°C |
| Dynamic Impedance (ZZT) | 9.0 Ω at IZT = 25 mA - determines output voltage variation under load transients (ΔVZ ≈ ΔIZ × 9 Ω) |
| Knee Current (IZK) | 0.25 mA - minimum current needed to enter usable regulation region; critical for low-power biasing circuits |
| Reverse Leakage (IR) | ≤1 µA at VR = 12.2 V - ensures minimal quiescent current in standby or high-impedance sensing nodes |
| Thermal Resistance | 30°C/W junction-to-TAB1 - enables thermal design using PCB copper area under TAB 1 as primary heatsink path |
| ESD Rating | >16 kV per Human Body Model - supports handling and assembly without external ESD protection in most board-level environments |
Pinout & Package
The 1PMT5929AE3/TR13 uses a 2-terminal DO-216 surface-mount package with cathode identified by TAB 1. The full metallic bottom and locking tab provide mechanical retention and thermal conduction to the PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary thermal path and electrical connection point; must be soldered to copper pour for rated 3.0 W operation |
| Opposite Pad | Anode | Standard anode terminal; no thermal function; connects to system ground or return path |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and reflow while delivering 3.0 W power handling in footprint smaller than DO-41 or SOD-123 |
| Integral heat sink locking tab | TAB 1 acts as both cathode and low-thermal-resistance interface to PCB copper, eliminating need for external heatsinks |
| Full metallic bottom | Prevents solder flux entrapment during reflow, reducing post-assembly cleaning requirements and void risk |
| ESD robustness | >16 kV HBM rating allows safe handling and board integration without additional ESD suppression components |
Applications
| Industrial Power Supply Regulation | Automotive ECUs |
|---|---|
Use Scenario: Stabilizing 15 V reference for op-amp biasing and ADC reference in isolated DC-DC converter feedback loops. IC Role / Device Role / Timing Role: Precision voltage reference and shunt regulator maintaining stable 15 V despite input ripple and load variation. Use Value: Tight 5% tolerance and low 9.0 Ω dynamic impedance ensure <±75 mV regulation error under 8 mA load step, meeting industrial-grade accuracy. | Use Scenario: Overvoltage clamp protecting CAN transceiver supply rail against load-dump transients up to 40 V. IC Role / Device Role / Timing Role: Shunt protection device clamping rail voltage to 15 V before downstream IC damage occurs. Use Value: 3.0 W rating and 30°C/W thermal resistance allow sustained clamping for >100 ms at 125°C ambient when mounted on ≥1 cm² copper. |
| Medical Sensor Biasing | Telecom Line Card Protection |
Use Scenario: Providing low-noise, stable 15 V bias for photodiode transimpedance amplifiers in portable diagnostic equipment. IC Role / Device Role / Timing Role: Low-leakage (≤1 µA) voltage reference ensuring minimal dark-current error in high-gain analog front-ends. Use Value: Sub-µA reverse leakage at 12.2 V prevents signal offset drift in picoampere-level sensor interfaces. | Use Scenario: Protecting 15 V auxiliary rails in DSLAM line cards from induced surges on nearby copper pairs. IC Role / Device Role / Timing Role: Fast-response shunt limiter absorbing surge energy before TVS diodes trigger, extending system surge lifetime. Use Value: 0.25 mA knee current enables early conduction onset, reducing peak clamping voltage by ~1.2 V versus higher-IZK alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5929BRLG | Same 15 V, ±5%, DO-41 through-hole package; 1.2 W rating; no metallic bottom or locking tab | Requires manual or wave soldering; unsuitable for high-density SMT layouts or thermal-critical 3 W use cases | Select only if legacy through-hole assembly or lower power (<1.2 W) operation is required |
| BZX84-C15LT1G | SOT-23 package; 15 V, ±5%; 300 mW rating; 30 Ω dynamic impedance; 5 µA IR at 12 V | Limited to low-power biasing; cannot sustain 3 W clamping; higher impedance degrades regulation under load | Choose only for space-constrained, sub-300 mW applications where thermal performance is secondary |

FAQ
What is the maximum continuous power dissipation for 1PMT5929AE3/TR13?
The 1PMT5929AE3/TR13 is rated for 3.0 W DC power dissipation when TAB 1 temperature is maintained at 60°C. Power must be linearly derated above 60°C at 33.3 mW/°C, reaching zero at 150°C junction temperature. This rating assumes adequate PCB copper area under TAB 1 per the thermal resistance specification of 30°C/W.
How is cathode polarity identified on the 1PMT5929AE3/TR13 package?
The cathode of the 1PMT5929AE3/TR13 is unambiguously designated by TAB 1 - the larger, metallic terminal pad on one end of the DO-216 package. This is confirmed in the mechanical specifications section of the MSC0995 datasheet and is consistent across all Powermite® Zener devices in the 1PMT59xxB series.
Does 1PMT5929AE3/TR13 meet any industry-standard ESD ratings?
Yes, the 1PMT5929AE3/TR13 has an ESD rating exceeding 16 kV per the Human Body Model (HBM), as specified in the FEATURES section of the MSC0995 datasheet. This rating applies to both terminals and supports robust handling and assembly without requiring additional on-board ESD protection circuitry.
What is the reverse leakage current specification for 1PMT5929AE3/TR13 at 12.2 V?
At VR = 12.2 V and TL = 30°C, the reverse leakage current (IR) for the 1PMT5929AE3/TR13 is guaranteed to be ≤1 µA maximum. This value is specified in the Electrical Characteristics table of the MSC0995 datasheet and is critical for low-power biasing and high-impedance sensing applications.
Can 1PMT5929AE3/TR13 be used in reflow soldering processes?
Yes, the 1PMT5929AE3/TR13 is qualified for standard lead-free reflow soldering per J-STD-020. Its Powermite® package is explicitly designed for compatibility with automatic insertion and reflow assembly, and the full metallic bottom eliminates solder flux entrapment - a known reliability risk in plastic-molded SMT packages.
