Product details
Overview
1PMT5954BE3/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 121.6 mA maximum Zener current - used for precision voltage regulation and overvoltage protection in industrial power supplies.
For engineers reviewing the 1PMT5954BE3/TR13 datasheet, 1PMT5954BE3/TR13 pinout, 1PMT5954BE3/TR13 application, or 1PMT5954BE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (30°C/W junction-to-TAB), ESD rating (>16 kV HBM), reverse leakage (<6500 µA at 1 V), and compatibility with automated insertion equipment.
Technical Context
This Zener diode operates as a two-terminal voltage reference device with cathode designated by TAB 1, requiring no external biasing or control logic. Its full metallic bottom and integral heat sink locking tab enable direct thermal conduction to the PCB pad, supporting stable regulation under sustained 3.0 W dissipation when mounted on adequate copper area.
The device exhibits low reverse leakage (<6500 µA at VR = 1 V) and tight knee characteristics (IZK = 0.25 mA, ZZK = 700 Ω), enabling reliable clamping in low-current standby modes. Voltage regulation is specified at TL = 30°C with 20-second stabilization after DC current application per Note 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 160 V ±5% at IZT = 2.3 mA - defines nominal regulation point with predictable deviation across temperature |
| 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 - determines output voltage variation under small-signal current changes |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies temperature rise per watt dissipated into PCB copper |
| ESD Rating | >16 kV per Human Body Model - ensures robustness during handling and board assembly |
| Reverse Leakage (IR) | <6500 µA at VR = 1 V - limits standby power loss in high-impedance bias networks |
| Knee Current (IZK) | 0.25 mA - minimum current needed to enter regulated region with acceptable voltage slope |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5954B | Same 160 V, ±5%, 3.0 W rating but in DO-41 through-hole package; no metallic bottom or locking tab | Requires manual or wave soldering; lacks integrated thermal path to PCB | Select when legacy through-hole assembly or higher mechanical ruggedness is prioritized over SMT automation |
| SMBJ160A | TVS diode with 160 V standoff, 200 W peak pulse power, but higher clamping voltage (≈220 V) and no precise regulation | Designed for transient suppression only - not suitable for voltage reference use | Select only for surge-only protection where regulation accuracy is irrelevant |
Compared with 1N5954B and SMBJ160A, the 1PMT5954BE3/TR13 uniquely combines SMT manufacturability, 3.0 W steady-state dissipation via TAB 1 thermal conduction, and ±5% regulation tolerance - making it optimal for compact, thermally constrained, and automated production of regulated power rails.

FAQ
What is the Zener voltage tolerance for 1PMT5954BE3/TR13?
The 1PMT5954BE3/TR13 has a standard Zener voltage tolerance of ±5% at 160 V, measured at IZT = 2.3 mA and TAB 1 temperature of 30°C. Tighter tolerances of ±2% (suffix C) and ±1% (suffix D) are available as custom order options, but the E3/TR13 variant ships with ±5% as specified in the MSC0995 datasheet revision F.
How is thermal management handled for 1PMT5954BE3/TR13?
Thermal management for 1PMT5954BE3/TR13 relies on direct conduction from the silicon junction to TAB 1, which serves as both cathode and primary heat sink. With a junction-to-TAB thermal resistance of 30°C/W, maintaining TAB 1 at ≤60°C enables full 3.0 W dissipation. PCB layout must provide adequate copper area under TAB 1 to achieve this.
Is 1PMT5954BE3/TR13 compatible with automated SMT assembly?
Yes, 1PMT5954BE3/TR13 is explicitly designed for compatibility with automatic insertion equipment. Its Powermite® package features a unique locking tab and full metallic bottom that prevent rotation and flux entrapment during reflow, ensuring high first-pass yield in high-speed pick-and-place and reflow processes.
What is the maximum reverse leakage current for 1PMT5954BE3/TR13?
The maximum reverse leakage current for 1PMT5954BE3/TR13 is 6500 µA at VR = 1 V, as specified in the Electrical Characteristics table of the MSC0995 datasheet. This value is measured at TL = 30°C and reflects worst-case leakage under low-voltage reverse bias - critical for low-power standby circuit design.
Does 1PMT5954BE3/TR13 have ESD protection built-in?
Yes, 1PMT5954BE3/TR13 has an ESD rating exceeding 16 kV per the Human Body Model (HBM), as confirmed in the FEATURES section of the MSC0995 datasheet. This intrinsic robustness eliminates the need for external ESD protection in most board-level handling and operational environments.
