Product details
Overview
BZD27C100PH from Taiwan Semiconductor is a 100 V, 1 W surface-mount Zener diode in Sub SMA package, rated for 5 mA test current, 60 Ω dynamic resistance, and ±0.09%/°C temperature coefficient, used for voltage regulation and transient suppression in DC/DC converters and SMPS.
For engineers reviewing the BZD27C100PH datasheet, BZD27C100PH pinout, BZD27C100PH application, or BZD27C100PH equivalent, key selection criteria include zener voltage tolerance (94–106 V), non-repetitive peak pulse power (150 W @ 10/1000 μs), leakage current (≤1 μA @ 75 V), thermal resistance (RθJA = 88 °C/W), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The BZD27C100PH operates as a single-die, unidirectional silicon Zener diode with cathode-band polarity indication. It delivers precise 100 V nominal breakdown under 5 mA test current, with tight ±6% tolerance (94–106 V) and low 60 Ω differential resistance ensuring stable regulation under load variation.
Designed for surge protection and voltage reference in high-reliability environments, it supports 150 W non-repetitive peak pulse power per 10/1000 μs waveform, junction temperature range of −55 to +175 °C, and meets J-STD-020 moisture sensitivity level 1 - enabling reflow compatibility without baking.

FAQ
What is the zener voltage tolerance of BZD27C100PH?
The BZD27C100PH has a zener voltage range of 94 V to 106 V at 5 mA test current, representing ±6% tolerance around the nominal 100 V rating. This tolerance is guaranteed across production lots and validated per AEC-Q101 stress testing, ensuring consistent regulation performance in feedback and clamp circuits using the BZD27C100PH.
Is BZD27C100PH qualified for automotive applications?
Yes, the BZD27C100PH is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life required for automotive electronics. This qualification makes the BZD27C100PH suitable for use in engine control units, body control modules, and lighting systems where reliability under harsh conditions is critical.
What is the maximum non-repetitive peak pulse power for BZD27C100PH?
The BZD27C100PH supports 150 W non-repetitive peak pulse power under the 10/1000 μs waveform condition, as specified in its absolute maximum ratings. This rating applies specifically to the BZD27C10PH through BZD27C100PH variants and enables effective transient suppression in power rails without requiring additional TVS devices alongside the BZD27C100PH.
Does BZD27C100PH require baking before reflow soldering?
No, the BZD27C100PH has moisture sensitivity level (MSL) 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions and placed directly into reflow without pre-baking. This eliminates process steps and reduces risk of moisture-related defects during SMT assembly of boards using the BZD27C100PH.
What package type does BZD27C100PH use?
The BZD27C100PH uses the Sub SMA package - a low-profile surface-mount case with matte tin-plated leads, UL 94V-0 flammability rating, and cathode band polarity marking. Its dimensions and pad layout are optimized for high-density PCBs, and it weighs approximately 0.019 g, supporting automated pick-and-place handling in the BZD27C100PH manufacturing flow.
