Product details
Overview
1PMT5930BT1 from onsemi is a 3.2 W surface-mount Zener diode in the POWERMITE® (DO−216AA) package, with nominal Zener voltage 16 V (min 15.2 V, max 16.8 V) at 23.4 mA test current, 12.2 Ω dynamic impedance, and 0.25 µA reverse leakage at 12.2 V. It delivers stable voltage regulation in space-constrained portable power rails.
For engineers reviewing the 1PMT5930BT1 datasheet, pinout, applications, or equivalent options, key selection criteria include thermal performance at 75°C cathode temperature, ESD robustness (>16 kV HBM), low-profile height (1.1 mm max), and tape-and-reel packaging (12,000 units/reel for T3 variant).
Technical Context
This device operates as a precision shunt voltage regulator, maintaining stable output under varying load and input conditions via controlled reverse breakdown. Its Zener voltage exhibits a positive temperature coefficient above ~5 V, with typical TC of +3.5 mV/°C near 16 V.
Thermal design centers on the cathode tab: maximum DC power dissipation is 3.2 W only when cathode temperature is held at 75°C, enabled by the integral heat sink tabs and full metallic bottom. Junction-to-cathode thermal resistance is 23°C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.2–16.8 V @ IZT = 23.4 mA - defines regulated output range under standard test conditions |
| Power Dissipation (PD) | 3.2 W @ Ttab = 75°C - usable power headroom depends on cathode thermal management |
| Zener Impedance (ZZT) | 12.2 Ω @ IZT = 23.4 mA - determines output voltage stability under load transients |
| Reverse Leakage (IR) | 0.25 µA @ VR = 12.2 V - ensures minimal quiescent current in standby regulation |
| ESD Rating | Class 3 (>16 kV HBM) - supports robust handling in automated assembly and end-use environments |
| Package Height | Max 1.1 mm - enables use in ultra-thin consumer devices like smartphones and wearables |
| Footprint Area | 8.45 mm² - 50% smaller than SMA, reducing PCB real estate without sacrificing thermal performance |
Pinout & Package
The 1PMT5930BT1 is housed in the POWERMITE® (JEDEC DO−216AA) plastic surface-mount package, featuring an integral heat sink and locking tabs for mechanical retention. Cathode is marked by a polarity band and designated Terminal 1; Anode is Terminal 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener reference terminal / heat path | Primary thermal interface; must be connected to copper pour or thermal pad for rated 3.2 W operation |
| 2 (Anode) | Reference ground / return path | Low-impedance connection required to minimize voltage error from series resistance |
Key Features
| Feature | Design Value |
|---|---|
| Integral heat sink tabs | Enables 3.2 W dissipation in 1.1 mm profile by direct thermal coupling to PCB copper |
| Full metallic bottom | Eliminates flux entrapment during reflow, improving solder joint reliability and thermal transfer |
| Polarity band marking | Unambiguous cathode identification for automated optical inspection and placement verification |
| Pb-free (G-suffix) option | Complies with RoHS Directive 2011/65/EU without derating or performance trade-off |
| 12 mm tape-and-reel (T3) | Supports high-speed pick-and-place at 12,000 units/reel, reducing line changeover frequency |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4744A | Through-hole DO-41 package; 14 V nominal; 1 W rating; no ESD rating specified | Requires larger PCB area and manual or wave soldering; unsuitable for high-density SMT lines | Select when legacy through-hole assembly or lower-cost prototyping is prioritized over size and ESD robustness |
| BZX84-C16 | SOT-23 package; 16 V nominal; 300 mW rating; 150°C max junction temp | Limited to low-power signal-level regulation; cannot sustain 3.2 W continuous dissipation | Select only for signal-clamping or low-current reference roles where thermal load is <300 mW |
Compared with 1N4744A and BZX84-C16, the 1PMT5930BT1 uniquely combines 3.2 W power handling, 1.1 mm profile, and >16 kV ESD rating in a surface-mount package-enabling compact, robust, high-power regulation unattainable with either alternative.

FAQ
What is the maximum continuous power dissipation for the 1PMT5930BT1?
The 1PMT5930BT1 has a maximum DC power dissipation of 3.2 W, but only when the cathode (Terminal 1) is maintained at 75°C. This requires proper thermal design-such as a dedicated copper pour or thermal pad-to achieve the specified 23°C/W junction-to-cathode thermal resistance. At ambient temperature alone, derating applies per the datasheet's power derating curve.
Does the 1PMT5930BT1 have a Pb-free option?
Yes, the 1PMT5930BT1G variant is the Pb-free version of the 1PMT5930BT1, fully compliant with RoHS Directive 2011/65/EU. The "G" suffix indicates lead-free terminations and compatible packaging, with identical electrical and thermal specifications-no performance trade-offs or requalification needed.
How is polarity identified on the 1PMT5930BT1 package?
The 1PMT5930BT1 uses a cathode polarity band-typically a white or black stripe-located adjacent to Terminal 1. Per the datasheet marking diagram and JEDEC DO−216AA standard, Terminal 1 is always the cathode and Terminal 2 is the anode. This marking is visible under optical inspection and supports automated placement verification.
What is the Zener impedance of the 1PMT5930BT1 at its test current?
The 1PMT5930BT1 has a maximum Zener impedance (ZZT) of 12.2 Ω measured at its specified Zener test current of 23.4 mA. This value reflects dynamic impedance under AC conditions (iZ(rms) = 0.1 × IZ(dc) at 60 Hz) and directly impacts output voltage regulation accuracy during load transients.
Can the 1PMT5930BT1 be used in automotive under-hood applications?
The 1PMT5930BT1 supports an operating temperature range of −55°C to +150°C, meeting under-hood thermal requirements. However, it is not AEC-Q200 qualified. For production automotive applications requiring qualification, consult onsemi's AEC-Q200-compliant Zener portfolio-this part is suitable for non-safety-critical, non-qualified designs such as aftermarket modules or prototyping.
