Product details
Overview
1PMT5955BE3/TR13 from Microsemi is a 180 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 900 Ω dynamic impedance at 2.1 mA test current and thermal resistance of 30°C/W junction-to-TAB1. It serves as a precision voltage reference or overvoltage clamp in high-reliability industrial power supplies.
For engineers reviewing the 1PMT5955BE3/TR13 datasheet, 1PMT5955BE3/TR13 pinout, 1PMT5955BE3/TR13 application, or 1PMT5955BE3/TR13 equivalent, key selection criteria include its 180 V nominal Zener voltage, 3.0 W power handling in a DO-216 outline, ESD rating >16 kV HBM, and full metallic bottom eliminating solder flux entrapment during reflow assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage under varying load and temperature conditions. Its design centers on thermal management via an integral heat sink locking tab and direct metal-to-PCB thermal path through the full metallic bottom.
It is characterized at TL = 30°C with IZT = 2.1 mA, exhibits 7000 µA max reverse leakage at VR = 1 V, and supports tight-tolerance variants (±2%, ±1%) via suffixes C/D - though 1PMT5955BE3/TR13 uses standard ±5% tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 180 V ±5% at IZT = 2.1 mA - defines clamping threshold in overvoltage protection circuits |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - enables compact 3 W regulation without external heatsink |
| Dynamic Impedance (ZZT) | 900 Ω at IZT = 2.1 mA - indicates moderate voltage regulation sensitivity to current change |
| Thermal Resistance | 30°C/W junction-to-TAB1 - allows accurate thermal derating when mounted on copper pad |
| ESD Rating | >16 kV per Human Body Model - ensures robustness during automated handling and board assembly |
| Reverse Leakage (IR) | ≤7000 µA at VR = 1 V - confirms low standby power loss in high-impedance bias networks |
| Package Outline | DO-216 - standardized surface-mount footprint compatible with EIA-481 tape-and-reel (13″ reel: 12,000 pcs) |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary thermal and electrical connection point; must be soldered to copper pour for thermal performance |
| Lead 2 | Anode | Standard anode terminal; electrically isolated from TAB 1; used for circuit return path |
Key Features
| Feature | Design Value |
|---|---|
| Full metallic bottom | Eliminates solder flux entrapment during reflow, improving long-term solder joint reliability |
| Integral heat sink locking tab | Provides mechanical anchoring and direct thermal conduction path from junction to PCB |
| ESD robustness | >16 kV HBM rating reduces risk of field failure in handling and system integration |
| Automated insertion compatibility | DO-216 geometry and tape-and-reel packaging support high-speed pick-and-place placement |
Applications
| Industrial Power Supply Clamping | Telecom Line Card Protection |
|---|---|
Use Scenario: Clamp transient surges on 48 V DC distribution rails in programmable logic controller (PLC) backplanes. IC Role / Device Role / Timing Role: Zener diode operating in reverse breakdown to limit voltage excursions above 180 V. Use Value: Prevents damage to downstream DC-DC converters rated for ≤200 V input by absorbing up to 3.0 W surge energy. | Use Scenario: Protect analog front-end components on telecom line cards exposed to lightning-induced transients. IC Role / Device Role / Timing Role: Standby shunt regulator and overvoltage limiter on -48 V supply monitoring nodes.

IC Role / Device Role / Timing Role: Transient voltage suppressor placed across bus inputs to limit fault voltage to safe levels. Use Value: Withstands repeated 3.0 W pulses due to Powermite® thermal design and metallic bottom conduction. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5955BTR | Same 180 V Zener voltage and ±5% tolerance, but in DO-41 axial package; no metallic bottom or locking tab | Lacks surface-mount compatibility and thermal performance; requires through-hole mounting and external heatsinking | Select only if legacy through-hole assembly is required and thermal derating can be managed externally |
| SMBJ180A | TVS diode with 180 V standoff voltage and 600 W peak pulse power; not a regulated Zener reference | Designed for transient suppression only; higher leakage and no DC regulation capability | Choose for surge-only protection where precise DC clamping is unnecessary |
Compared with 1N5955BTR and SMBJ180A, the 1PMT5955BE3/TR13 uniquely combines 3.0 W DC power handling, surface-mount DO-216 form factor, and integrated thermal path - making it optimal for space-constrained, thermally demanding Zener reference or clamping roles.

FAQ
What is the Zener voltage tolerance for 1PMT5955BE3/TR13?
The 1PMT5955BE3/TR13 has a standard Zener voltage tolerance of ±5% at IZT = 2.1 mA and TL = 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D respectively, but 1PMT5955BE3/TR13 specifically uses the standard ±5% version as indicated by the 'B' suffix in the part number.
How is thermal performance managed in the 1PMT5955BE3/TR13 package?
The 1PMT5955BE3/TR13 uses the Powermite® package with a full metallic bottom and integral heat sink locking tab to conduct heat directly from the junction to the PCB. Its specified thermal resistance is 30°C/W junction-to-TAB1, enabling effective derating when TAB 1 is soldered to an adequate copper area - critical for sustaining 3.0 W dissipation in compact layouts.
Is 1PMT5955BE3/TR13 compatible with lead-free reflow processes?
Yes, the 1PMT5955BE3/TR13 is qualified for lead-free reflow soldering per J-STD-020. Its molded Powermite® package and metallization support peak temperatures up to 260°C. The full metallic bottom also improves wetting and reduces voiding risk during reflow, aligning with IPC-A-610 Class 2/3 requirements.
What does the 'E3/TR13' suffix indicate in 1PMT5955BE3/TR13?
The 'E3' denotes Microsemi's RoHS-compliant, lead-free finish, and 'TR13' specifies tape-and-reel packaging on a 13-inch reel containing 12,000 units per EIA-481 standard. This distinguishes it from TR7 (7-inch reel, 3,000 pcs) and non-tape versions, ensuring compatibility with high-volume SMT assembly lines.
Can 1PMT5955BE3/TR13 be used as a replacement for axial 1N5955B diodes?
No - while both share 180 V Zener voltage and ±5% tolerance, the 1PMT5955BE3/TR13 is a surface-mount DO-216 device with integrated thermal features, whereas the 1N5955B is axial DO-41. They are not pin-compatible or drop-in replacements; PCB layout, thermal design, and assembly process differ fundamentally between the two packages.
