Product details
Overview
BZD27C62PWH from Taiwan Semiconductor is a 1 W, 62 V ±5% tolerance silicon Zener diode in SOD-123W package, rated for 10 mA test current, 86.5 V clamping voltage at 1 A surge, and operating up to +175°C junction temperature - used for precision voltage regulation and overvoltage protection in automotive power rails.
For engineers reviewing the BZD27C62PWH datasheet, BZD27C62PWH pinout, BZD27C62PWH application, or BZD27C62PWH equivalent, key selection criteria include zener voltage tolerance (±5%), low leakage (<1.0 µA @ VR), AEC-Q101 qualification, and SOD-123W thermal performance (RθJA = 85°C/W).
Technical Context
The BZD27C62PWH operates as a single-die, surface-mount Zener diode with sharp reverse breakdown at nominal 62 V, designed for stable voltage reference and transient suppression in DC power domains. Its 1 W steady-state dissipation and 300 W non-repetitive pulse rating (100 µs) support both regulation and surge clamping roles.
Thermal design is enabled by SOD-123W's low RθJL (22°C/W) and RθJC (24°C/W), while its AEC-Q101 qualification confirms suitability for automotive under-hood environments. The device exhibits a positive temperature coefficient of +0.09%/°C, ensuring predictable drift across -55°C to +175°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage VZ | 58.9–65.1 V @ IZT = 10 mA - defines precise regulation band for 62 V nominal rail |
| Power dissipation Ptot | 1.0 W @ TA = 25°C - sets continuous thermal limit on standard PCB copper pad |
| Clamping voltage VC | 86.5 V @ IRSM = 1 A (10/1000 µs) - determines maximum transient voltage seen by protected circuit |
| Zener impedance ZZT | 80 Ω @ IZT = 10 mA - impacts regulation accuracy under load variation |
| Leakage current IR | <1.0 µA @ VR = 47 V - ensures minimal standby power loss in high-impedance bias networks |
| Junction temperature TJ | -55°C to +175°C - enables operation in engine control units and power converters |
| Temperature coefficient αVZ | +0.09%/°C - allows accurate drift compensation in temperature-critical references |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BZT52C62S | Same 62 V nominal, SOD-123 package, but rated 500 mW and not AEC-Q101 qualified | Limited to commercial-grade power supplies; unsuitable for automotive under-hood use | Select BZD27C62PWH when AEC-Q101 compliance and 1 W power handling are mandatory |
| Vishay BZX84-C62 | SOT-23 package, 250 mW rating, ±5% tolerance, no AEC-Q101 certification | Lower power density and thermal capability; incompatible with high-surge automotive transients | Choose BZD27C62PWH for designs requiring robust 300 W pulse clamping and 175°C operation |

FAQ
What is the zener voltage tolerance of BZD27C62PWH?
The BZD27C62PWH has a zener voltage range of 58.9 V to 65.1 V at 10 mA test current, corresponding to a ±5% tolerance around the nominal 62 V rating. This tolerance is guaranteed per the manufacturer's electrical specifications table and applies under standard test conditions (TA = 25°C).
Is BZD27C62PWH qualified for automotive applications?
Yes, the BZD27C62PWH is AEC-Q101 qualified, meaning it has passed stress tests including high-temperature reverse bias, temperature cycling, and humidity testing required for automotive under-hood and chassis applications. This qualification is explicitly stated in the product features section of the official datasheet.
What is the maximum clamping voltage of BZD27C62PWH during surge events?
The BZD27C62PWH clamps at 86.5 V when subjected to a 1 A, 10/1000 µs waveform surge - a value specified in the Electrical Specifications table. This clamping voltage defines the upper voltage limit imposed on protected circuitry during transient overvoltage events.
Does BZD27C62PWH have a specified temperature coefficient?
Yes, the BZD27C62PWH has a temperature coefficient of +0.09%/°C, indicating that its zener voltage increases by approximately 0.09% per degree Celsius rise in junction temperature. This value is confirmed in the Electrical Specifications table and supports thermal drift analysis in precision reference designs.
What package type does BZD27C62PWH use, and what are its key mechanical attributes?
The BZD27C62PWH uses the SOD-123W package: a low-profile surface-mount case with matte tin-plated leads, UL 94V-0 flammability rating, cathode polarity marked by a band, and approximate weight of 0.016 g.
