Product details
Overview
1PMT5922BT1G from onsemi is a 3.2 W surface-mount Zener diode in the POWERMITE® (DO−216AA) package, with nominal Zener voltage 7.5 V at 50 mA test current, maximum dynamic impedance 6.0 Ω at IZT, and reverse leakage ≤5.0 µA at VR = 6.0 V. It delivers stable voltage regulation in space-constrained portable power rails and ESD-sensitive signal lines.
For engineers reviewing the 1PMT5922BT1G datasheet, pinout, applications, or equivalent options, key selection criteria include its 7.5 V regulation tolerance (±4.7%), low-profile 1.1 mm height, Pb-free compliance, 16 kV HBM ESD rating, and thermal performance matching SMA with 50% smaller footprint.
Technical Context
The 1PMT5922BT1G operates as a precision shunt voltage regulator, maintaining stable output voltage across varying load currents via controlled reverse breakdown. Its Zener voltage is specified at 7.5 V (min 7.12 V, max 7.88 V) with tight 50 mA test current (IZT) and low 6.0 Ω dynamic impedance (ZZT), enabling accurate clamping in feedback loops and reference circuits.
Thermally, it achieves 3.2 W DC power dissipation when cathode tab is held at 75°C, supported by RJcathode = 23°C/W and RJanode = 35°C/W. The full metallic bottom and integral heat sink tabs enhance PCB heat transfer, while the DO−216AA outline ensures compatibility with standard SMT reflow profiles up to 260°C for 10 seconds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5227BS-7-F | 300 mW SOT-323 package; 3.3 V Zener; higher ZZT (17 Ω) | Limited to low-power signal-level clamping, not suitable for >100 mA loads | Select only for space-limited signal rails where 3.2 W dissipation is unnecessary |
| SMBJ7.5A | 600 W peak power TVS; unidirectional; 8.33 V breakdown; larger SMB package | Designed for surge suppression (IEC 61000-4-2), not precision regulation | Choose when protecting against lightning-induced transients-not for steady-state voltage reference |
Compared with MMBZ5227BS-7-F and SMBJ7.5A, the 1PMT5922BT1G uniquely balances 3.2 W continuous regulation, 7.5 V precision, and ultra-low profile-making it optimal for compact, thermally demanding, and ESD-critical embedded power nodes.

FAQ
What is the Zener voltage tolerance of the 1PMT5922BT1G?
The 1PMT5922BT1G has a nominal Zener voltage of 7.5 V with a guaranteed range of 7.12 V to 7.88 V at IZT = 50 mA, corresponding to ±4.7% tolerance. This specification is measured at thermal equilibrium (TL = 25°C) and ensures predictable clamping behavior in production designs using the 1PMT5922BT1G.
Can the 1PMT5922BT1G replace an SMA-packaged Zener diode without layout changes?
No - the 1PMT5922BT1G uses the DO−216AA (POWERMITE®) package, which is physically smaller (2.05 × 2.18 mm) than SMA (4.5 × 2.7 mm). While it offers equivalent thermal performance, PCB land patterns must be updated to match the 1PMT5922BT1G's specific solder footprint and terminal spacing per Case 457-04 dimensions.
What is the maximum reverse leakage current for the 1PMT5922BT1G at 6.0 V?
The 1PMT5922BT1G specifies maximum reverse leakage current (IR) of 5.0 µA at VR = 6.0 V and TL = 25°C. This low leakage supports energy-efficient operation in battery-powered devices where standby current must remain below 10 µA - a key design parameter confirmed for the 1PMT5922BT1G.
Does the 1PMT5922BT1G meet JEDEC standards for surface-mount packages?
Yes - the 1PMT5922BT1G is registered by JEDEC as DO−216AA. Its mechanical dimensions, thermal ratings, and solderability (260°C for 10 s) comply with JEDEC standards for plastic surface-mount discrete devices, ensuring interoperability with automated assembly processes used for the 1PMT5922BT1G.
Is the 1PMT5922BT1G suitable for use as a voltage reference in precision ADC circuits?
The 1PMT5922BT1G can serve as a cost-effective reference in moderate-precision ADC applications (e.g., 10–12 bit) where its 7.5 V ±4.7% tolerance, 6.0 Ω dynamic impedance, and low 5 µA leakage provide adequate stability. For higher-accuracy systems, dedicated bandgap references remain preferred - but the 1PMT5922BT1G delivers validated performance in production sensor nodes using the 1PMT5922BT1G.
