Product details
Overview
1PMT5954CE3/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 high-reliability DC power rails.
For engineers reviewing the 1PMT5954CE3/TR13 datasheet, 1PMT5954CE3/TR13 pinout, 1PMT5954CE3/TR13 application, or 1PMT5954CE3/TR13 equivalent, key selection criteria include Zener voltage accuracy (±5%), thermal resistance (30°C/W junction-to-TAB), ESD rating (>16 kV HBM), low reverse leakage (<1 µA at 121.6 V), and compatibility with automated SMT assembly per EIA-481 tape-and-reel packaging.
Technical Context
This device operates as a single-terminal voltage reference diode with cathode designated by TAB 1, requiring no external biasing circuitry. Its full metallic bottom and integral heat sink locking tab enable direct thermal coupling to PCB copper, supporting stable 3.0 W operation without heatsink under defined thermal conditions.
The 1PMT5954CE3/TR13 exhibits tight knee characteristics (IZK = 0.25 mA, ZZK = 6500 Ω) and low reverse leakage (IR ≤ 1 µA at VR = 121.6 V), making it suitable for low-current reference and clamping applications where stability across -55°C to +150°C junction temperature range is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 160 V ±5% at IZT = 2.3 mA, TL = 30°C - defines regulated output voltage with production tolerance band. |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - maximum continuous DC power handling with specified thermal mounting condition. |
| Dynamic Impedance (ZZT) | 700 Ω at IZT = 2.3 mA - small-signal AC impedance affecting regulation stiffness near operating point. |
| Max Zener Current (IZM) | 121.6 mA - derived from 3.0 W / 160 V; sets upper limit for safe DC conduction without exceeding power rating. |
| Thermal Resistance | 30°C/W junction-to-TAB 1 - quantifies thermal path efficiency; requires adequate PCB copper area for thermal management. |
| ESD Rating | >16 kV per Human Body Model - supports robust handling during automated assembly and field operation. |
| Reverse Leakage | ≤1 µA at VR = 121.6 V - ensures minimal standby current in clamping or reference configurations. |
Pinout & Package

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 TO-204AA (DO-41) through-hole package; 5 W rating; higher thermal resistance (~50°C/W). | Requires through-hole assembly and external heatsinking for equivalent power handling; not SMT-compatible. | Select when legacy board layout or higher power margin is required, and automated SMT is unavailable. |
| BZX84-C160 | SOT-23 package; 160 V Zener; 300 mW rating; 10× lower power capability; 100× higher dynamic impedance (~70 kΩ). | Limited to low-current bias/reference use; unsuitable for 3.0 W clamping or regulation. | Select only for space-constrained, low-power signal-level referencing where thermal performance is non-critical. |

FAQ
What is the Zener voltage tolerance for 1PMT5954CE3/TR13?
The 1PMT5954CE3/TR13 has a standard Zener voltage tolerance of ±5% at 160 V nominal, measured at 2.3 mA test current with TAB 1 held at 30°C. Tighter tolerances (±2%, ±1%) are available with suffixes C and D respectively, but the CE3 variant specifies ±5%. This tolerance directly impacts regulation accuracy in precision reference circuits.
How is thermal management handled for 1PMT5954CE3/TR13 in PCB layout?
The 1PMT5954CE3/TR13 relies on TAB 1 as its primary thermal path, with a specified junction-to-TAB thermal resistance of 30°C/W. To achieve rated 3.0 W dissipation, designers must connect TAB 1 to a minimum 1-inch² copper area (1 oz. thickness) on the PCB. The full metallic bottom and locking tab ensure efficient conduction without solder voids or flux entrapment.
Is 1PMT5954CE3/TR13 compatible with lead-free reflow processes?
Yes, the 1PMT5954CE3/TR13 is qualified for standard lead-free reflow profiles per J-STD-020, including peak temperatures up to 260°C. Its molded Powermite® package and metallization system are designed to withstand thermal cycling without delamination or parameter shift. The EIA-481 tape-and-reel format (TR13) supports automated pick-and-place compatibility.
What does the "E3" suffix indicate in 1PMT5954CE3/TR13?
The "E3" suffix in 1PMT5954CE3/TR13 denotes compliance with Microsemi's standard environmental specification: Pb-free (lead-free) terminations and RoHS-compliant materials. It confirms that the device meets EU RoHS Directive 2011/65/EU and related exemptions, with no intentionally added lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE.
Can 1PMT5954CE3/TR13 be used for bidirectional transient suppression?
No - the 1PMT5954CE3/TR13 is a unidirectional Zener diode with cathode designated by TAB 1. It conducts only in reverse breakdown (cathode positive relative to anode) and provides no forward surge protection. For bidirectional TVS applications, a dedicated bidirectional TVS diode such as SMAJ160A or equivalent must be used instead.
