Product details
Overview
BZD27C130PW from Taiwan Semiconductor is a 130 V, 5 mA test-current zener diode in SOD-123W package, rated for 1.0 W steady-state power dissipation and 185 V clamping voltage under 10/1000 µs surge, used for precision voltage reference and overvoltage protection in industrial power rails.
For engineers reviewing the BZD27C130PW datasheet, BZD27C130PW pinout, BZD27C130PW application, or BZD27C130PW equivalent, key selection factors include its 123.5–136.5 V zener tolerance at 5 mA, 5000 Ω dynamic impedance, 0.81 µA leakage at 100 V, and -55°C to +175°C junction temperature range.
Technical Context
The BZD27C130PW operates as a single-die silicon zener diode with sharp reverse breakdown characteristics, optimized for stable regulation under low test current (5 mA) and high-voltage clamping during transient events. Its thermal resistance (RθJA = 85°C/W) supports operation up to 175°C junction temperature when mounted on standard PCB copper pads.
It delivers 185 V clamping voltage under 10/1000 µs waveform per IEC 61000-4-5, with 100 V temperature coefficient of zener voltage (0.09–0.13 %/°C), enabling predictable drift compensation in reference circuits across wide ambient ranges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BZT52C130S | Same 130 V nominal zener, but SOD-323 package (smaller footprint, higher RθJA = 125°C/W) | Limited to lower average power (0.5 W) and reduced surge handling (PRSM = 50 W) | Select for space-constrained designs where thermal margin allows derating below 0.5 W continuous |
| Vishay BZX84-C130 | SOD-323 package, 130 V nominal, but wider VZ tolerance (123.5–143 V) and higher ZZT (6000 Ω) | Higher regulation uncertainty and less stable under varying load currents | Acceptable for non-critical clamping where ±8% voltage variation is tolerable |
Compared with BZD27C130PW, BZT52C130S offers smaller size but sacrifices 50% steady-state power and surge capacity, while BZX84-C130 trades tighter voltage control for broader availability and lower cost in consumer-grade applications.

FAQ
What is the zener voltage tolerance of BZD27C130PW at 5 mA test current?
The BZD27C130PW has a guaranteed zener voltage range of 123.5 V (minimum) to 136.5 V (maximum) when tested at IZT = 5 mA, corresponding to ±5% tolerance around the nominal 130 V rating. This specification is validated per Taiwan Semiconductor's D2203 datasheet revision and applies across the full operating temperature range.
Can BZD27C130PW be used for transient voltage suppression in 24 V automotive systems?
Yes, BZD27C130PW is rated for 100 W non-repetitive peak pulse power under 10/1000 µs waveform, with a clamping voltage of 185 V - sufficient to protect downstream 24 V-rated CAN transceivers and microcontrollers during ISO 7637-2 load-dump events. Its 175°C maximum junction temperature also supports under-hood placement.
What is the thermal resistance from junction to ambient for BZD27C130PW?
The BZD27C130PW has a junction-to-ambient thermal resistance (RθJA) of 85°C/W when mounted on a standard 5 mm × 5 mm copper pad, as specified in the Absolute Maximum Ratings table. This value assumes natural convection and defines the temperature rise per watt of dissipated power in typical PCB layouts.
Does BZD27C130PW meet RoHS and halogen-free requirements?
Yes, BZD27C130PW is RoHS compliant and halogen-free per IEC 61249-2-21. The device uses matte tin-plated leads and UL 94V-0 compliant molding compound, and passes JESD201 Class 2 whisker testing - all confirmed in Taiwan Semiconductor's official documentation (Version D2203).
What is the leakage current specification for BZD27C130PW at 100 V reverse bias?
The BZD27C130PW exhibits a maximum leakage current (IR) of 0.81 µA when biased at 100 V reverse voltage and measured at 25°C ambient, as stated in the Electrical Specifications table. This ultra-low leakage supports high-impedance reference networks and minimizes standby power loss in battery-backed systems.
