Product details
Overview
BZT52C36-G from Taiwan Semiconductor is a 36 V, ±5% tolerance Zener diode in SOD-123 package, rated for 350 mW power dissipation and 2 mA test current, with 90 Ω dynamic impedance at 2 mA and 0.1 µA leakage at 25.2 V reverse bias - used for precision voltage regulation in low-power analog circuits and reference supply rails.
For engineers reviewing the BZT52C36-G datasheet, BZT52C36-G pinout, BZT52C36-G application, or BZT52C36-G equivalent, key selection criteria include nominal Zener voltage (36 V), tight 5% tolerance, SOD-123 surface-mount compatibility, thermal resistance (357 °C/W), and low leakage performance at 25.2 V.
Technical Context
The BZT52C36-G operates as a single-die, cathode-banded Zener diode optimized for stable reverse-breakdown regulation under controlled test conditions (IZ = 2 mA). Its junction temperature range spans −55 °C to +150 °C, and it meets JESD201 Class 1A whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements.
It exhibits a typical temperature coefficient of +30.4 mV/°C, indicating positive drift with rising temperature, and delivers 37.4 V maximum Zener voltage at IZTC = 2 mA - critical for thermal stability analysis in voltage-reference designs where ambient variation exceeds ±40 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 34.0–38.0 V at IZT = 2 mA - defines regulation window for stable 36 V reference under nominal bias |
| Power Dissipation (PD) | 350 mW - limits continuous DC power handling in PCB space-constrained SOD-123 layout |
| Zener Impedance (ZZT) | 90 Ω at IZT = 2 mA - determines output voltage ripple rejection in low-current regulation loops |
| Leakage Current (IR) | 0.1 µA at VR = 25.2 V - ensures minimal error current in high-impedance reference divider networks |
| Junction Temp Range (TJ) | −55 °C to +150 °C - supports operation in automotive under-hood and industrial control environments |
| Thermal Resistance (RθJA) | 357 °C/W - requires careful copper pour design to avoid exceeding 150 °C junction limit at full PD |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5236B-7-F | Same 36 V nominal, but ±5% tolerance only at IZ = 20 mA; higher ZZT = 17 Ω at 20 mA vs. 90 Ω at 2 mA for BZT52C36-G | Optimized for higher-current regulation (>10 mA); less suitable for micro-power reference use | Select MMBZ5236B-7-F only if circuit delivers ≥15 mA Zener current and thermal budget allows higher PD |
| 1N4736A | Through-hole DO-41 package; 36 V ±5%, but PD = 1 W and ZZT = 10 Ω at 31 mA - incompatible SMT footprint and bias point | Designed for legacy through-hole power supplies; not drop-in replaceable in SOD-123 layouts | Choose 1N4736A only for manual assembly or high-power derating scenarios where SMT is not required |
Compared with MMBZ5236B-7-F and 1N4736A, the BZT52C36-G offers optimal trade-off of SMT compatibility, low-current regulation fidelity (2 mA test point), and thermal efficiency in space-constrained designs - making it preferred for modern embedded voltage references.

FAQ
What is the nominal Zener voltage and tolerance of the BZT52C36-G?
The BZT52C36-G has a nominal Zener voltage of 36 V with a guaranteed tolerance of ±5% at IZT = 2 mA, meaning its actual breakdown voltage falls between 34.0 V and 38.0 V under standard test conditions. This tolerance is specified per the Taiwan Semiconductor datasheet Version C2007 and applies directly to the BZT52C36-G device.
What package type does the BZT52C36-G use, and what are its key mechanical features?
The BZT52C36-G uses the SOD-123 surface-mount package - measuring approximately 2.5 mm × 1.3 mm - with matte tin-plated leads compliant with J-STD-002, UL 94V-0 flammability rating, and JESD201 Class 1A whisker resistance. The cathode is marked by a visible band, and the device weighs ~10.55 mg. These attributes are confirmed in the official Taiwan Semiconductor mechanical data sheet for BZT52C36-G.
What is the maximum power dissipation and thermal resistance of the BZT52C36-G?
The BZT52C36-G has a maximum power dissipation (PD) of 350 mW at TA = 25 °C and a junction-to-ambient thermal resistance (RθJA) of 357 °C/W. These values define its safe operating area and require appropriate PCB copper area to maintain junction temperature below 150 °C. Both parameters are explicitly listed in the Absolute Maximum Ratings table of the BZT52C36-G datasheet.
How does the leakage current specification of the BZT52C36-G impact low-power design?
The BZT52C36-G specifies a maximum leakage current (IR) of 0.1 µA at VR = 25.2 V, which minimizes parasitic loading in high-impedance reference dividers and extends battery life in always-on IoT nodes. This value is measured per the Electrical Specifications table and directly supports ultra-low-quiescent designs where sub-microamp drain is critical - a verified characteristic of the BZT52C36-G.
Is the BZT52C36-G suitable for automotive applications, and what temperature range does it support?
Yes, the BZT52C36-G supports junction temperatures from −55 °C to +150 °C and is qualified to JESD201 Class 1A whisker testing and J-STD-020 Level 1 moisture sensitivity - making it suitable for under-hood and BCM applications. Its thermal and reliability specs are validated per Taiwan Semiconductor's qualification standards for the BZT52C36-G part number.
