Product details
Overview
1PMT5930BE3/TR7 from Microsemi is a 16 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 10 Ω dynamic impedance at 23.4 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 DC power rails and regulator feedback paths.
For engineers reviewing the 1PMT5930BE3/TR7 datasheet, 1PMT5930BE3/TR7 pinout, 1PMT5930BE3/TR7 application, or 1PMT5930BE3/TR7 equivalent, key selection criteria include its 16 V nominal Zener voltage, 3.0 W power handling in a DO-216 outline, low reverse leakage (≤1 µA at 12.2 V), ESD rating >16 kV HBM, and compatibility with automated SMT assembly.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across its specified test current range. Its Powermite® package integrates a full metallic bottom and locking tab to enhance thermal conduction and mechanical stability during reflow soldering.
The device exhibits low dynamic impedance (10 Ω) at IZT = 23.4 mA and maintains stable regulation down to knee current IZK = 0.25 mA, where Zener impedance rises to 600 Ω - enabling reliable performance in low-current bias and sensing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 16 V ±5% at IZT = 23.4 mA - defines regulated output voltage under standard test conditions |
| Power Dissipation | 3.0 W at TAB 1 = 60°C - maximum continuous DC power handled with defined thermal mounting |
| Dynamic Impedance ZZT | 10 Ω at IZT = 23.4 mA - low AC impedance ensures minimal voltage variation under load transients |
| Knee Current IZK | 0.25 mA - minimum current needed to enter useful regulation region |
| Reverse Leakage IR | ≤1 µA at VR = 12.2 V - ensures negligible standby current in clamping or reference circuits |
| Thermal Resistance | 30°C/W junction-to-TAB1 - quantifies thermal path efficiency for heatsinking via PCB copper pad |
| ESD Rating | >16 kV per HBM - supports robust handling in automated manufacturing without special ESD controls |
Pinout & Package
The 1PMT5930BE3/TR7 uses a DO-216 surface-mount package with cathode designated by TAB 1. The full metallic bottom and integral locking tab serve as both mechanical anchor and thermal interface to the PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB 1 | Cathode | Primary heat-sinking terminal and electrical cathode connection; must be soldered to thermal pad for rated 3.0 W operation |
| Lead 2 | Anode | Standard anode connection; mounted opposite TAB 1 on DO-216 outline |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount Powermite® package | DO-216 outline enables high-density layout while delivering 3.0 W power handling comparable to larger through-hole Zeners |
| Full metallic bottom | Eliminates solder flux entrapment during reflow, improving long-term reliability and solder joint integrity |
| Integral heat sink locking tab | TAB 1 provides direct thermal path to PCB copper, achieving 30°C/W junction-to-pad thermal resistance |
| ESD robustness | >16 kV HBM rating reduces risk of field failure and simplifies ESD control in production environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5930BTR | Same 16 V ±5%, but in DO-41 through-hole package; no metallic bottom or locking tab; 3.0 W derated above 50°C ambient | Requires manual or wave soldering; unsuitable for high-density SMT layouts or automated insertion | Select when legacy through-hole assembly or higher-temperature ambient operation (>60°C) is required |
| BZX584C16 | 16 V ±5% in SOD-123; 500 mW power rating; 15 Ω ZZT; no specified ESD rating | Limited to low-power biasing or signal-level clamping; cannot replace 1PMT5930BE3/TR7 in 3.0 W applications | Select only for space-constrained, sub-1 W designs where thermal performance is secondary |
Compared with 1N5930BTR and BZX584C16, the 1PMT5930BE3/TR7 uniquely delivers 3.0 W SMT Zener performance with integrated thermal management and industrial-grade ESD robustness - making it the only choice for high-reliability, high-power-density 16 V regulation or clamping.

FAQ
What is the Zener voltage tolerance for 1PMT5930BE3/TR7?
The 1PMT5930BE3/TR7 has a standard Zener voltage tolerance of ±5% at 16 V, measured at IZT = 23.4 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 reference and clamping circuits using the 1PMT5930BE3/TR7.
How is thermal performance specified for 1PMT5930BE3/TR7?
The 1PMT5930BE3/TR7 specifies a thermal resistance of 30°C/W junction-to-TAB1, meaning each watt of dissipated power raises the junction temperature 30°C above the TAB 1 temperature. Its 3.0 W rating applies only when TAB 1 is maintained at ≤60°C - requiring adequate PCB copper area and thermal vias. This thermal behavior is intrinsic to the Powermite® package's metallic bottom and locking tab design in the 1PMT5930BE3/TR7.
Can 1PMT5930BE3/TR7 be used in low-current applications near the knee region?
Yes, the 1PMT5930BE3/TR7 maintains usable regulation down to IZK = 0.25 mA, where Zener impedance rises to 600 Ω. At this point, voltage deviation remains within specification, enabling use in ultra-low-power bias networks. However, designers must account for increased impedance-induced voltage shift in circuits relying on the 1PMT5930BE3/TR7 at currents below 23.4 mA.
What does the "E3/TR7" suffix indicate for 1PMT5930BE3/TR7?
The "E3" denotes tape-and-reel packaging per EIA-481 standard with 3,000 units per 7-inch reel; "TR7" confirms this configuration. This packaging supports automated SMT placement and ensures consistent orientation (cathode marked by TAB 1) during pick-and-place. The E3/TR7 format is essential for high-volume manufacturing of boards using the 1PMT5930BE3/TR7.
Is 1PMT5930BE3/TR7 suitable for automotive applications?
The 1PMT5930BE3/TR7 operates from −55°C to +150°C junction temperature and meets ISO 9001 quality standards, but it is not AEC-Q200 qualified. While used in industrial and medical systems with similar environmental stress, automotive deployment requires additional qualification testing. For automotive-grade alternatives, consult Microchip's AEC-Q200-certified Zener portfolio - the 1PMT5930BE3/TR7 itself is not certified for automotive use.
