Product details

Overview

BZD27C150P from Taiwan Semiconductor is a 1 W, 147 V nominal zener voltage diode in Sub SMA package, rated for 175 °C junction temperature and 5 mA test current, with 150 Ω typical differential resistance and ±0.09 %/°C temperature coefficient-used for precision voltage reference and overvoltage protection in power supply feedback loops.

For engineers reviewing the BZD27C150P datasheet, BZD27C150P pinout, BZD27C150P application, or BZD27C150P equivalent, key selection criteria include zener voltage tolerance (±6.3 %), low leakage (<1 μA @ 110 V), surge capability (100 W, 10/1000 μs), thermal resistance (R_θJA = 88 °C/W), and RoHS/halogen-free compliance.

Technical Context

The BZD27C150P operates as a single-die silicon zener diode optimized for stable reverse-bias regulation under DC and transient conditions. Its 147 V nominal zener voltage is specified at 5 mA test current, with 150 Ω typical dynamic resistance ensuring tight regulation across load variations.

Designed for surface-mount use in Sub SMA package, it supports junction temperatures from –55 °C to +175 °C and delivers 100 W non-repetitive peak pulse power (10/1000 μs) for surge suppression-distinct from lower-voltage variants (e.g., BZD27C100P) which support 150 W.

Yes, BZD27C150P supports non-repetitive peak pulse power dissipation of 100 W for a 10/1000 μs waveform, as specified in the Absolute Maximum Ratings table. This makes it suitable for clamping transient overvoltages in DC power rails, provided the surge duty cycle remains low to avoid thermal accumulation.

What is the maximum junction temperature for BZD27C150P?

The BZD27C150P has a maximum junction temperature (T_J) of +175 °C, enabling reliable operation in high-ambient environments such as industrial motor drives and automotive under-hood applications. This rating is maintained across its full storage temperature range of –55 °C to +175 °C.

Is BZD27C150P RoHS and halogen-free compliant?

Yes, BZD27C150P is RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the Features section. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002 for solderability.

What package type does BZD27C150P use?
