Product details
Overview
BZT52C62 RHG from Taiwan Semiconductor is a surface-mount 62 V ±5% tolerance Zener diode in SOD-123F package, rated for 500 mW power dissipation and tested at 2 mA zener current, used for precision voltage reference and low-power stabilization in DC/DC converters and adapter circuits.
For engineers reviewing the BZT52C62 RHG datasheet, BZT52C62 RHG pinout, BZT52C62 RHG application, or BZT52C62 RHG equivalent, key selection criteria include nominal zener voltage (62.0 V), zener impedance (215 Ω at 2 mA), leakage current (≤0.045 µA at 43.4 V), thermal resistance (350 °C/W), and RoHS/halogen-free compliance.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage under varying load or input conditions. Its 62.0 V nominal zener voltage is specified with ±5% tolerance at IZT = 2 mA, and exhibits 215 Ω dynamic impedance (ZZT) under that test condition.
The device features a single-die configuration in moisture-sensitive level-1 SOD-123F package, with matte tin-plated terminals solderable per J-STD-002 and junction temperature range of −65 °C to +150 °C. Forward voltage is 1.0 V at 10 mA forward current.
Key Specifications

| Zener impedance ZZT | 215 Ω (measured at 2 mA; defines voltage regulation sensitivity to current variation) |
| Leakage current IR | ≤0.045 µA at 43.4 V (ensures minimal standby power loss in high-impedance reference paths) |
| Junction-to-ambient RθJA | 350 °C/W (determines thermal rise under load; requires adequate PCB copper area for full rating) |
| Forward voltage VF | 1.0 V at 10 mA (supports use as clamp or protection diode in forward conduction mode) |
| Package | SOD-123F (standardized 3.3–3.9 mm body length; compatible with automated SMT placement and reflow) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5262B-7-F (Diodes Inc.) | Same 62 V nominal, ±5% tolerance, SOD-123 package; 200 mW rating vs. 500 mW | Limited to lower-power reference roles; unsuitable for >200 mW dissipation scenarios | Select when board space is constrained and thermal budget permits lower power rating |
| SZBZX84-C62LT1G (onsemi) | 62 V ±5%, SOT-23 package; 350 mW rating; higher leakage (≤1 µA at 43.4 V) | Higher leakage may affect precision biasing; larger footprint than SOT-23 but smaller than SOD-123F | Prefer for legacy SOT-23 footprints where thermal margin allows 350 mW operation |
Compared with MMBZ5262B-7-F and SZBZX84-C62LT1G, the BZT52C62 RHG delivers higher power capability (500 mW) and lower leakage (≤0.045 µA), making it optimal for thermally demanding or ultra-low-current reference designs where SOD-123F footprint is acceptable.

FAQ
What is the zener voltage tolerance of the BZT52C62 RHG?
The BZT52C62 RHG has a nominal zener voltage of 62.0 V with a ±5% tolerance, meaning its actual breakdown voltage falls between 58.9 V and 65.1 V when tested at 2 mA. This tolerance is confirmed in the Electrical Specifications table of the official Taiwan Semiconductor datasheet (Version G1804). The BZT52C62 RHG maintains this specification across its qualified operating temperature range.
What package type does the BZT52C62 RHG use?
The BZT52C62 RHG uses the SOD-123F surface-mount package, as explicitly stated in the Ordering Information section and Mechanical Data table of the Taiwan Semiconductor datasheet. It features matte tin-plated leads, moisture sensitivity level 1, and standardized dimensions (3.3–3.9 mm length, 1.5–1.7 mm width). The BZT52C62 RHG is not offered in SOT-23 or other variants.
What is the maximum power dissipation rating for the BZT52C62 RHG?
The BZT52C62 RHG is rated for 500 mW maximum power dissipation at ambient temperature (TA = 25 °C), as listed in both the KEY PARAMETERS and ABSOLUTE MAXIMUM RATINGS sections. Derating is required above 25 °C at 3.5 mW/°C, based on its 350 °C/W junction-to-ambient thermal resistance. This rating applies to the BZT52C62 RHG in its standard SOD-123F package with recommended PCB pad layout.
What is the leakage current specification for the BZT52C62 RHG?
The BZT52C62 RHG has a maximum leakage current (IR) of 0.045 µA when measured at 43.4 V reverse bias, per the Electrical Specifications table. This ultra-low leakage supports high-impedance reference applications. The value is confirmed for the BZT52C62 RHG specifically - not interpolated from adjacent voltages - and reflects testing at TA = 25 °C.
Is the BZT52C62 RHG RoHS and halogen-free compliant?
Yes, the BZT52C62 RHG complies with RoHS Directive 2011/65/EU and WEEE 2002/96/EC, and is halogen-free per IEC 61249-2-21, as stated in the FEATURES section of the Taiwan Semiconductor datasheet. These compliance attributes apply directly to the BZT52C62 RHG part number and are verified for the SOD-123F packaging configuration shipped under the RHG reel code.
