Taiwan Semiconductor Corporation 1PGSMC5364

Overview

1PGSMC5364 from Taiwan Semiconductor is a surface-mount 33 V ±5% Zener diode in DO-214AB (SMC) package, rated for 5 W steady-state power dissipation, 175 °C maximum junction temperature, and 10 mA zener test current. It serves as a precision voltage reference and overvoltage clamp in DC/DC converters and industrial power supplies.

For engineers reviewing the 1PGSMC5364 datasheet, 1PGSMC5364 pinout, 1PGSMC5364 application, or 1PGSMC5364 equivalent, key selection criteria include nominal zener voltage (33 V), dynamic impedance (40 Ω at 10 mA), leakage current (0.5 μA at 25.1 V), thermal resistance (22 °C/W junction-to-case), and RoHS/halogen-free compliance for high-reliability board-level protection.

Technical Context

This single-die Zener diode uses photo-glass passivated junction technology to ensure stable breakdown characteristics and low inductance-critical for fast transient suppression in switching regulators. Its DO-214AB (SMC) package supports automated placement and meets J-STD-020 moisture sensitivity level 1.

Thermal performance is characterized with R_θJC = 22 °C/W and R_θJA = 55 °C/W on a 16 mm × 16 mm Cu pad, enabling reliable operation up to 175 °C junction temperature under defined PCB layout conditions.

FAQ

What is the nominal zener voltage and tolerance of the 1PGSMC5364?

The 1PGSMC5364 has a nominal zener voltage of 33 V with a tolerance of ±5%, corresponding to a minimum of 31.35 V and maximum of 34.65 V at 10 mA test current (I_ZT). This tolerance is confirmed in the Electrical Specifications table of the official datasheet (Version D2102). The 1PGSMC5364 achieves this via tight process control of the photo-glass passivated junction.

What is the maximum power dissipation and thermal derating behavior of the 1PGSMC5364?

The 1PGSMC5364 is rated for 5 W DC power dissipation at lead temperature (T_L) of 75 °C, with linear derating above that temperature. Its junction-to-lead thermal resistance is 20 °C/W, and junction-to-ambient is 55 °C/W when mounted on a 16 mm × 16 mm Cu pad. The 1PGSMC5364 must be used within these limits to avoid exceeding its 175 °C maximum junction temperature.

Is the 1PGSMC5364 RoHS compliant and halogen-free?

Yes, the 1PGSMC5364 is RoHS compliant and halogen-free per IEC 61249-2-21. These compliance attributes are explicitly stated in the FEATURES section of the official datasheet (Version D2102). The 1PGSMC5364 uses matte tin-plated leads and UL 94V-0 molding compound to meet both environmental and safety standards.

What package type does the 1PGSMC5364 use, and what are its mechanical highlights?

The 1PGSMC5364 uses the DO-214AB (SMC) surface-mount package. Key mechanical features include polarity indicated by a cathode band, weight of approximately 0.210 g, UL 94V-0 flammability rating, and JESD201 Class 2 whisker resistance. The 1PGSMC5364 is optimized for automated placement and reflow soldering per J-STD-002.

How does the 1PGSMC5364 compare to standard through-hole Zener diodes like 1N5364B?

The 1PGSMC5364 offers identical 33 V/5 W electrical ratings but in a surface-mount DO-214AB package versus the through-hole DO-201AD of the 1N5364B. It features lower dynamic impedance (40 Ω vs. 50 Ω), tighter process control, and J-STD-020 Level 1 moisture sensitivity-making the 1PGSMC5364 preferable for high-density, automated manufacturing. Both share the same core Zener function, but the 1PGSMC5364 is purpose-built for modern SMT lines.
