Taiwan Semiconductor Corporation 1PGSMC5360

Overview

1PGSMC5360 from Taiwan Semiconductor is a 5W surface-mount Zener diode in DO-214AB (SMC) package, with nominal zener voltage 25V (min 23.75V, max 26.25V), test current 4mA, and dynamic impedance 50Ω at I_ZT. It operates from −55°C to +175°C junction temperature and is used for voltage regulation and overvoltage protection in DC/DC converters.

For engineers reviewing the 1PGSMC5360 datasheet, 1PGSMC5360 pinout, 1PGSMC5360 application, or 1PGSMC5360 equivalent, key selection criteria include its 25V nominal zener voltage, 5W power rating, 50Ω zener impedance at 4mA, DO-214AB mechanical outline, and compliance with J-STD-020 moisture sensitivity level 1.

Technical Context

This single-die Zener diode uses photo-glass passivated junction technology for stable breakdown characteristics and low leakage. Its 50Ω dynamic impedance at 4mA and 1Ω knee impedance at 1mA support precise voltage clamping in transient suppression and reference circuits.

Designed for automated SMT placement, it features matte tin-plated leads compliant with J-STD-002 solderability and meets JESD201 Class 2 whisker resistance. The DO-214AB package delivers R_θJL = 20°C/W and R_θJA = 55°C/W on a 16mm × 16mm Cu pad PCB.

FAQ

What is the nominal zener voltage and tolerance of the 1PGSMC5360?

The 1PGSMC5360 has a nominal zener voltage of 25 V with a tolerance of ±5%, corresponding to a guaranteed range of 23.75 V to 26.25 V at 4 mA test current. This tolerance is defined per the device marking code P360B and confirmed in the Electrical Specifications table of the official TSC datasheet Version D2102. The 1PGSMC5360 maintains this specification across its operating temperature range.

What package type does the 1PGSMC5360 use, and what are its key mechanical features?

The 1PGSMC5360 uses the DO-214AB (SMC) surface-mount package, featuring gull-wing leads, a cathode band for polarity identification, and UL 94V-0 flammability-rated molding compound. Its mechanical outline complies with JEDEC standards, and it weighs approximately 0.210 g. The 1PGSMC5360 is qualified for moisture sensitivity level 1 per J-STD-020, eliminating pre-reflow baking requirements.

What is the maximum DC zener current (I_ZM) for the 1PGSMC5360, and how is it derived?

The maximum DC zener current I_ZM for the 1PGSMC5360 is 190 mA, calculated from its 5 W power rating and minimum zener voltage (23.75 V): I_ZM = P_D / V_Z(min) ≈ 5 W / 23.75 V ≈ 210 mA, conservatively rated to 190 mA in the datasheet to account for thermal derating and long-term reliability. This value is explicitly listed in the Electrical Specifications table for the 1PGSMC5360.

Is the 1PGSMC5360 suitable for automotive applications?

The 1PGSMC5360 supports junction temperatures up to +175°C and is RoHS- and halogen-free compliant, meeting baseline environmental and thermal requirements for under-hood automotive modules. However, it is not AEC-Q200 qualified, so it should not be used in safety-critical or mission-critical automotive subsystems unless validated per customer-specific qualification protocols. For non-safety automotive lighting or accessory power, the 1PGSMC5360 is commonly deployed.

How does the 1PGSMC5360 compare to the 1PGSMC5359 in terms of zener voltage and impedance?

The 1PGSMC5359 has a nominal zener voltage of 24 V (range 22.8–25.2 V) and 50 Ω dynamic impedance at 4 mA, while the 1PGSMC5360 is rated at 25 V (23.75–26.25 V) with identical 50 Ω Z_ZT. Both share the same package, power rating, and thermal specs. The 1PGSMC5360 provides a 1 V higher regulation point, making it preferable where tighter headroom above 24 V rails is required-e.g., in 24 V system OVP circuits needing margin above nominal bus voltage.
