Product details
Overview
BZD27C160PW from Taiwan Semiconductor is a 1 W, 160 V nominal zener diode in SOD-123W package, designed for precision voltage regulation and transient overvoltage protection in power supply rails and reference circuits. It delivers a zener voltage range of 152–168 V at 5 mA test current, exhibits 6500 Ω dynamic impedance, and supports non-repetitive peak pulse power up to 100 W (10/1000 µs waveform).
For engineers reviewing the BZD27C160PW datasheet, BZD27C160PW pinout, BZD27C160PW application, or BZD27C160PW equivalent, key selection criteria include its 160 V nominal zener voltage, 5 mA test current, 6500 Ω zener impedance, 100 W surge rating, and SOD-123W surface-mount package compatibility with automated assembly.
Technical Context
The BZD27C160PW operates as a single-die silicon zener diode optimized for stable reverse-biased breakdown in low-profile SMD applications. Its thermal design supports junction temperatures from –55 °C to +175 °C, with RθJA = 85 °C/W and RθJC = 24 °C/W enabling reliable operation under sustained 1 W dissipation on standard PCB copper pads.
It features low leakage current (≤0.67 µA at 120 V), a temperature coefficient of zener voltage of +0.09 to +0.13 %/°C, and clamping voltage of 224 V under 10/1000 µs surge conditions - confirming suitability for high-voltage rail stabilization and ESD/surge suppression where tight voltage tolerance and predictable thermal behavior are required.

Equivalent & Alternatives
The following parts are listed as comparable options for similar zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BZT03-C160 | Same 160 V nominal zener voltage, but in DO-41 package (axial lead); 1.3 W Ptot; higher ZZT (10 kΩ) | Requires through-hole assembly; less suitable for high-density SMT designs | Select BZD27C160PW for SMT volume production; choose BZT03-C160 only if axial mounting or higher continuous power is needed. |
| Vishay BZX84-C160 | SOT-23 package; 250 mW Ptot; 160 V VZ at 5 mA; ZZT = 120 Ω - significantly lower impedance but lower power | Limited to low-power reference or signal-level clamping; cannot handle 1 W continuous or 100 W surge | Choose BZD27C160PW where 1 W dissipation or 100 W surge capability is required; BZX84-C160 suits space-constrained, low-power bias networks. |
Compared with BZT03-C160 and BZX84-C160, the BZD27C160PW uniquely balances 1 W power handling, 100 W surge rating, and SOD-123W SMT compatibility - making it optimal for industrial power supplies and high-voltage protection where both thermal robustness and automated assembly are mandatory.

FAQ
What is the nominal zener voltage and tolerance of the BZD27C160PW?
The BZD27C160PW has a nominal zener voltage of 160 V with a guaranteed range of 152 V to 168 V at 5 mA test current. This ±5% tolerance is specified per the manufacturer's electrical characteristics table and reflects the device's precision for voltage reference and regulation applications where tight VZ control is critical.
What is the maximum non-repetitive peak pulse power rating for the BZD27C160PW?
The BZD27C160PW is rated for 100 W non-repetitive peak pulse power under a 10/1000 µs waveform, as confirmed in the Absolute Maximum Ratings table. This rating applies specifically to the BZD27C110PW through BZD27C220PW variants and enables effective transient suppression without external staging in 160 V systems.
Does the BZD27C160PW meet RoHS and halogen-free requirements?
Yes, the BZD27C160PW 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 and verified via material declarations - supporting environmentally regulated industrial and consumer product designs.
What is the zener impedance of the BZD27C160PW and why does it matter?
The BZD27C160PW exhibits a zener impedance (ZZT) of 6500 Ω at 5 mA test current. This value quantifies how much the output voltage changes with current variation - a higher ZZT means greater sensitivity to load or source fluctuations, which must be accounted for in precision reference designs using the BZD27C160PW.
What is the recommended PCB pad layout for the BZD27C160PW to achieve full 1.0 W power rating?
To achieve the full 1.0 W power dissipation rating at TA = 25 °C, the BZD27C160PW must be mounted on a 5 mm × 5 mm copper pad per the manufacturer's Mechanical Data section. Smaller pads reduce thermal conduction and derate power handling - the BZD27C160PW's RθJA of 85 °C/W assumes this minimum copper area.
