Product details
Overview
1PMT5954A/TR13 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 thermal resistance of 30°C/W junction-to-TAB1. It serves as a precision voltage reference or overvoltage clamp in industrial power supply feedback loops.
For engineers reviewing the 1PMT5954A/TR13 datasheet, 1PMT5954A/TR13 pinout, 1PMT5954A/TR13 application, or 1PMT5954A/TR13 equivalent, key selection criteria include its 160 V nominal Zener voltage, 3.0 W power handling in a DO-216 outline, low reverse leakage (≤6500 µA at 121.6 V), ESD rating >16 kV HBM, and compatibility with automated SMT assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage regulation across varying load currents. Its Powermite® package features a full metallic bottom and integral heat sink locking tab, enabling efficient thermal conduction directly from the die to the PCB pad via TAB 1 - the cathode terminal.
The device exhibits tight voltage control under defined test conditions: VZ = 160 V measured at IZT = 2.3 mA with TL = 30°C, and maintains regulation down to knee current IZK = 0.25 mA where ZZK = 6500 Ω, supporting low-current biasing applications.

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 Zener voltage but in DO-204AL (DO-41) through-hole package; 5 W rating; higher thermal resistance (50°C/W) | Requires through-hole assembly and larger board area; better suited for prototyping or low-volume manual builds | Select when legacy through-hole layout or higher single-pulse surge capability is required |
| BZX85C160 | 160 V Zener in DO-41 package; 1.3 W power rating; ±5% tolerance; no specified ESD rating | Limited to lower-power regulation; lacks ESD hardening and thermal performance of Powermite® | Select only for cost-sensitive, non-automated, low-power applications where 3.0 W headroom is unnecessary |

FAQ
What is the Zener voltage tolerance for 1PMT5954A/TR13?
The 1PMT5954A/TR13 has a standard Zener voltage tolerance of ±5% at 160 V nominal, measured at 2.3 mA test current and TAB 1 temperature of 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D respectively, but the base part number 1PMT5954A/TR13 specifies ±5%.
How is thermal management implemented in the 1PMT5954A/TR13 package?
The 1PMT5954A/TR13 uses the Powermite® package with TAB 1 as the cathode and primary thermal path. Its 30°C/W junction-to-TAB1 thermal resistance requires direct soldering of TAB 1 to a copper thermal pad on the PCB. The full metallic bottom and integral locking tab enhance heat transfer and mechanical stability during reflow.
What is the maximum reverse voltage that can be applied to 1PMT5954A/TR13 before breakdown?
The 1PMT5954A/TR13 begins regulating at its nominal Zener voltage of 160 V, with a guaranteed minimum breakdown voltage of 152 V (−5%) and maximum of 168 V (+5%). The absolute maximum reverse voltage before destructive failure is not specified, but the device is rated for 121.6 V reverse voltage (VR) at which reverse leakage remains ≤6500 µA.
Is 1PMT5954A/TR13 compatible with lead-free reflow processes?
Yes, the 1PMT5954A/TR13 is qualified for lead-free reflow per J-STD-020. Its Powermite® package withstands peak temperatures up to 260°C, and the full metallic bottom ensures reliable solder wetting without flux entrapment - critical for consistent void-free joints in Pb-free assembly.
What does the "TR13" suffix indicate in 1PMT5954A/TR13?
The "TR13" suffix indicates tape-and-reel packaging per EIA-481 standard on a 13-inch reel containing 12,000 units. This format supports high-speed automated pick-and-place equipment and is optimized for volume SMT production environments.
