Product details
Overview
1PMT5928BE3/TR7 from Microsemi is a 13 V ±5% surface-mount Zener diode in the Powermite® package, rated for 3.0 W DC power dissipation at TAB 1 = 60°C, with 7.0 Ω dynamic impedance at 28.8 mA test current and thermal resistance of 30°C/W junction-to-TAB1. It serves as a precision voltage reference or overvoltage clamp in compact power supply rails and industrial sensor interfaces.
For engineers reviewing the 1PMT5928BE3/TR7 datasheet, 1PMT5928BE3/TR7 pinout, 1PMT5928BE3/TR7 application, or 1PMT5928BE3/TR7 equivalent, key selection criteria include its DO-216 mechanical outline, cathode identification via TAB 1, ESD rating >16 kV HBM, low reverse leakage (≤1 µA at 10.4 V), and compatibility with automated SMT assembly per EIA-481 tape-and-reel packaging.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage regulation across varying load currents, with knee current IZK = 0.25 mA and knee impedance ZZK = 550 Ω - enabling reliable turn-on behavior in low-current bias networks. Its full metallic bottom and integral heat-sink locking tab directly conduct heat from the junction to PCB copper, supporting sustained 3.0 W dissipation when mounted on adequate thermal pads.
The device exhibits tight voltage tolerance (±5%), low forward voltage (1.2 V @ 200 mA), and specified performance over -55°C to +150°C junction temperature range. Reverse leakage remains ≤1 µA up to VR = 10.4 V, ensuring minimal standby power loss in battery-backed systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 13.0 V ±5% at IZT = 28.8 mA - defines regulated output voltage under nominal bias conditions |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - maximum continuous DC power handling with verified thermal path |
| Dynamic Impedance ZZT | 7.0 Ω at IZT = 28.8 mA - determines regulation sensitivity to load current changes |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies temperature rise per watt, critical for thermal pad design |
| ESD Rating | >16 kV per Human Body Model - ensures robustness during handling and board assembly |
| Reverse Leakage IR | ≤1 µA at VR = 10.4 V - limits quiescent current in high-impedance reference circuits |
| Knee Current IZK | 0.25 mA - minimum current required to enter usable regulation region |
Pinout & Package
Package: Powermite® (DO-216), molded surface-mount package with full metallic bottom and integral heat-sink locking tab; cathode designated by TAB 1; weight ≈ 0.016 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal and voltage reference node; must be connected to ground or low-impedance return path |

Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | Enables automated placement and reflow while delivering 3.0 W power handling in footprint smaller than DO-41 |
| Full metallic bottom | Eliminates solder flux entrapment risk and provides direct thermal conduction path to PCB copper |
| Integral heat-sink locking tab | Acts as mechanical anchor and thermal interface - improves reliability under thermal cycling |
| ESD robustness >16 kV HBM | Reduces need for external protection in ESD-prone environments like industrial control panels |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF13A (ON Semiconductor) | 13 V, 400 W peak pulse power, SOD-123 package, 100 ns response, no specified DC power rating | Designed for transient suppression only - not suitable for continuous regulation | Select only for surge clamping; not interchangeable for voltage reference use |
| BZX84-C13 (Diodes Inc.) | 13 V ±5%, 300 mW, SOT-23 package, 25 Ω ZZT, 350°C/W junction-to-ambient | Limited to low-power biasing; cannot sustain 3.0 W or match thermal performance | Use where space is critical and power < 300 mW; requires thermal redesign for 1PMT5928BE3/TR7 replacement |
Compared with SMF13A and BZX84-C13, the 1PMT5928BE3/TR7 uniquely supports continuous 3.0 W regulation in a surface-mount package with verified thermal path - making it irreplaceable in high-stability, high-power reference or clamp roles where DC dissipation and thermal management are primary constraints.

FAQ
What is the Zener voltage tolerance for 1PMT5928BE3/TR7?
The 1PMT5928BE3/TR7 has a standard Zener voltage tolerance of ±5% at 13.0 V, measured at IZT = 28.8 mA with TAB 1 held at 30°C. Tighter tolerances (±2% and ±1%) are available with suffixes C and D respectively, but the E3/TR7 variant specifies ±5%. This tolerance directly impacts regulation accuracy in precision reference applications.
How is cathode identification implemented on 1PMT5928BE3/TR7?
The cathode of the 1PMT5928BE3/TR7 is designated by TAB 1 - the larger metallic tab on the package bottom - which serves both as the electrical cathode connection and primary thermal interface. This mechanical marking eliminates ambiguity during automated placement and ensures correct orientation for thermal and electrical performance.
What is the maximum continuous power dissipation for 1PMT5928BE3/TR7?
The 1PMT5928BE3/TR7 is rated for 3.0 W DC power dissipation when TAB 1 is maintained at 60°C. This rating assumes proper thermal coupling to PCB copper; exceeding this condition risks junction temperature exceeding 150°C. Derating is required above 60°C ambient or with insufficient copper area.
Does 1PMT5928BE3/TR7 meet industry ESD standards?
Yes, the 1PMT5928BE3/TR7 has an ESD rating exceeding 16 kV per the Human Body Model (HBM), verified per ANSI/ESDA/JEDEC JS-001. This level of robustness supports direct handling and assembly in standard electronics manufacturing environments without additional ESD mitigation.
What packaging format is used for 1PMT5928BE3/TR7?
The 1PMT5928BE3/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 this 7-inch tape-and-reel configuration, ensuring compatibility with standard SMT pick-and-place equipment.
