Taiwan Semiconductor Corporation 1PGSMB5930

Overview

1PGSMB5930 from Taiwan Semiconductor is a surface-mount 16 V Zener diode in DO-214AA (SMB) package, rated for 3 W total power dissipation, with nominal zener voltage tolerance of ±5%, 10.0 Ω dynamic impedance at 23.4 mA test current, and maximum junction temperature of +175°C. It serves as a precision voltage reference and overvoltage clamp in DC/DC converters and power adapters.

For engineers reviewing the 1PGSMB5930 datasheet, 1PGSMB5930 pinout, 1PGSMB5930 application, or 1PGSMB5930 equivalent, key selection criteria include its 16 V nominal zener voltage, 23.4 mA test current, 10.0 Ω zener impedance, 12.2 V minimum clamping voltage, and DO-214AA thermal performance (R_θJA = 59°C/W).

Technical Context

The 1PGSMB5930 operates as a single-die, unidirectional Zener diode with glass-passivated junction for stable breakdown characteristics under reverse bias. Its low-inductance SMB package supports high-frequency transient suppression and automated SMT placement.

Designed for thermal reliability in compact power circuits, it delivers specified zener voltage (15.2–16.8 V) at 23.4 mA with 10.0 Ω dynamic impedance, and maintains leakage current ≤1 μA at 12.2 V while supporting up to 94 mA maximum DC zener current.

FAQ

What is the nominal zener voltage of the 1PGSMB5930?

The 1PGSMB5930 has a nominal zener voltage of 16 V, with a guaranteed range of 15.2 V (min) to 16.8 V (max) at 23.4 mA test current and 25°C ambient temperature. This ±5% tolerance is confirmed in the Electrical Specifications table of the Taiwan Semiconductor datasheet revision C2102. The 1PGSMB5930 achieves this specification using a photo glass-passivated silicon junction optimized for stable breakdown behavior.

What package type does the 1PGSMB5930 use?

The 1PGSMB5930 uses the DO-214AA (SMB) surface-mount package, as explicitly stated in the Mechanical Data and Ordering Information sections. It features matte tin-plated leads compliant with J-STD-002 solderability standards, a cathode band for polarity identification, and weighs approximately 0.100 g. The SMB outline is compatible with standard SMT pick-and-place equipment and meets UL 94V-0 flammability requirements.

What is the maximum power dissipation rating for the 1PGSMB5930?

The 1PGSMB5930 is rated for 3 W total power dissipation at lead temperature (T_L) of 75°C, measured on a 10 mm × 10 mm copper pad PCB per JESD51-3. Derating is required above 75°C at 33 mW/°C. This rating is validated by thermal resistance values: R_θJL = 21°C/W and R_θJA = 59°C/W. The 1PGSMB5930 maintains this rating under continuous DC operation within its specified junction temperature range of –55°C to +175°C.

How does the 1PGSMB5930 perform in terms of zener impedance?

The 1PGSMB5930 exhibits a dynamic zener impedance (Z_ZT) of 10.0 Ω at 23.4 mA test current and 25°C, as specified in the Electrical Specifications table. This low impedance ensures minimal voltage deviation under varying load currents, supporting stable regulation in feedback networks. The 1PGSMB5930 also specifies Z_ZK = 600 Ω at I_ZK = 0.25 mA, confirming predictable knee behavior near breakdown onset.

Is the 1PGSMB5930 suitable for automotive applications?

The 1PGSMB5930 is not AEC-Q200 qualified and is not recommended for automotive safety-critical applications. While it operates across –55°C to +175°C junction temperature and meets RoHS/halogen-free requirements, Taiwan Semiconductor's official documentation states these devices are "not designed for use in medical, life-saving, or life-sustaining applications." For automotive-grade Zener diodes, consult TSC's AEC-Q200-certified SMBZ series or equivalent qualified alternatives. The 1PGSMB5930 remains appropriate for industrial and consumer power supplies.
