Product details
Overview
1PMT5954AE3/TR7 from Microsemi is a 160 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 700 Ω dynamic impedance at 2.3 mA test current and 121.6 mA maximum Zener current - used for precision voltage regulation and overvoltage protection in high-reliability power supplies and industrial control circuits.
For engineers reviewing the 1PMT5954AE3/TR7 datasheet, 1PMT5954AE3/TR7 pinout, 1PMT5954AE3/TR7 application, or 1PMT5954AE3/TR7 equivalent, key selection factors include its 160 V nominal Zener voltage, 3.0 W thermal capability with metallic-tab heat sinking, DO-216 mechanical outline, ESD rating >16 kV HBM, and compatibility with EIA-481 tape-and-reel automated assembly.
Technical Context
This Zener diode operates as a two-terminal voltage reference device, with cathode designated by TAB 1 and anode connected to the molded body. Its full metallic bottom enables direct thermal conduction to the PCB, while the locking tab provides mechanical retention and supplemental heat sinking.
The device is characterized at TL = 30°C with Zener voltage measured 20 seconds after applying DC test current; dynamic impedance is derived using 60 Hz RMS AC current equal to 10% of IZT, per Micro Note 202 for voltage-current deviation analysis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 160 V ±5% at IZT = 2.3 mA - defines stable regulation point under nominal bias |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - sets maximum continuous thermal load with PCB heatsinking |
| Dynamic Impedance (ZZT) | 700 Ω at IZT = 2.3 mA - indicates voltage stability under small-signal AC perturbations |
| Max Zener Current (IZM) | 121.6 mA - derived from 3.0 W limit and VZ, determines absolute DC current ceiling |
| ESD Rating | >16 kV per Human Body Model - ensures robustness during handling and board assembly |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies thermal path efficiency to PCB copper pad |
| Reverse Leakage (IR) | 6500 µA max at VR = 121.6 V - specifies worst-case shunt loss below breakdown |
Pinout & Package
Package: Powermite® (DO-216), surface-mount, molded plastic with full metallic bottom and integral locking tab; cathode designated by TAB 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal and voltage reference node; must be connected to low-impedance ground or return plane |
| Molded Body | Anode | Electrically connected to internal anode structure; soldered to PCB pad for mechanical and electrical attachment |
Key Features
| Feature | Design Value |
|---|---|
| Full metallic bottom | Eliminates solder flux entrapment during reflow, improving long-term solder joint reliability |
| Integral locking tab | Acts as mechanical anchor and thermal interface, enhancing mounting stability and heat transfer |
| DO-216 mechanical outline | Enables compatibility with standard SMT pick-and-place equipment and EIA-481 tape-and-reel feeders |
| 16 kV HBM ESD rating | Reduces risk of electrostatic damage during manufacturing and field operation without external protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5375B | Same 160 V nominal VZ, but DO-204AL package, 5 W rating, higher thermal resistance (50°C/W) | Requires larger PCB footprint and less efficient thermal coupling than Powermite® | Choose when higher power headroom is needed and space allows larger through-hole or axial package |
| BZX85C160 | 160 V VZ, DO-41 package, 1.3 W rating, no metallic thermal tab | Limited to lower-power regulation; lacks integrated heat sink and flux-trap prevention | Prefer for cost-sensitive, low-duty-cycle applications where 3.0 W dissipation is not required |
Compared with 1N5375B and BZX85C160, the 1PMT5954AE3/TR7 delivers superior thermal performance in minimal area via its metallic-tab Powermite® construction, enabling reliable 3.0 W operation in space-constrained SMT designs where thermal management and assembly robustness are critical.

FAQ
What is the Zener voltage tolerance for 1PMT5954AE3/TR7?
The 1PMT5954AE3/TR7 has a standard Zener voltage tolerance of ±5% at 160 V nominal, measured at IZT = 2.3 mA with TAB 1 held at 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D, respectively, but the E3/TR7 variant uses the standard ±5% grade.
How is thermal performance defined for 1PMT5954AE3/TR7?
The 1PMT5954AE3/TR7 has a junction-to-TAB1 thermal resistance of 30°C/W and is rated for 3.0 W DC power dissipation when TAB 1 is maintained at 60°C. This requires adequate PCB copper area under TAB 1 to achieve effective heat spreading and avoid exceeding the 150°C maximum junction temperature.
Does 1PMT5954AE3/TR7 have polarity marking, and how is it identified?
Yes, the 1PMT5954AE3/TR7 uses TAB 1 as the cathode terminal, clearly designated in the mechanical drawings and electrical specifications. The molded body serves as the anode. No additional band or marking is present - orientation is determined solely by TAB 1 placement on the PCB footprint per DO-216 outline.
What packaging format is used for 1PMT5954AE3/TR7?
The 1PMT5954AE3/TR7 is supplied in EIA-481 compliant tape-and-reel format: 7-inch reels contain 3,000 units, and 13-inch reels contain 12,000 units. The TR7 suffix explicitly denotes the 7-inch tape-and-reel packaging configuration.
Can 1PMT5954AE3/TR7 be used in high-temperature environments?
Yes, the 1PMT5954AE3/TR7 is rated for junction and storage temperatures from -55°C to +150°C. Its Powermite® package design - including full metallic bottom and locking tab - maintains mechanical integrity and thermal performance across this full range, provided PCB layout supports adequate heat dissipation at elevated ambient conditions.
