Product details
Overview
BZT52-C3V6J from Nexperia is a ±5 % tolerance Zener diode in SOD123 package, rated for 3.6 V nominal Zener voltage at 5 mA, with 500 Ω max differential resistance and 5 μA max reverse current at 1 V, used for low-power voltage reference and overvoltage clamping in consumer power rails.
For engineers reviewing the BZT52-C3V6J datasheet, BZT52-C3V6J pinout, BZT52-C3V6J application, or BZT52-C3V6J equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (210 K/W junction-to-solder-point), forward voltage ≤0.9 V at 10 mA, total power dissipation up to 590 mW, and SOD123 footprint compatibility with automated SMT assembly.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage regulation across load and supply variations. Its 3.6 V nominal Zener voltage is specified at 5 mA test current, with temperature coefficient of −3.5 to 0.0 mV/K and low differential resistance ensuring minimal voltage drift under dynamic current conditions.
Designed for surface-mount use on FR4 PCBs with single-sided copper, it delivers 590 mW total power dissipation at Tamb ≤25 °C and withstands non-repetitive peak reverse power up to 40 W (100 μs pulse), supporting transient suppression in compact DC-DC feedback paths and I/O line protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.4 V to 3.8 V at IZ = 5 mA - defines stable regulation point for 3.3 V rail referencing and biasing |
| Differential Resistance (rdif) | ≤500 Ω - ensures <18 mV output shift per 9 mA load change, critical for precision analog references |
| Reverse Current (IR) | ≤5 μA at VR = 1 V - guarantees low leakage in standby mode for battery-powered systems |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - enables efficient anode-cathode conduction during fault clamping |
| Total Power Dissipation (Ptot) | 590 mW at Tamb ≤25 °C - supports continuous operation in thermally constrained PCB layouts |
| Junction-to-Solder-Point Rth | 210 K/W - allows direct thermal coupling to cathode pad for improved power handling in high-density designs |
| Package | SOD123 - 2.8 mm × 1.7 mm footprint with 0.7 mm lead pitch, compatible with IPC-7351B standard reflow profiles |
Pinout & Package
SOD123 plastic surface-mounted package with two leads: compact 2.8 mm × 1.7 mm outline, 0.7 mm lead pitch, and cathode-marking band aligned to Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side) | Cathode (K) | Connected to regulated output node; marking band identifies polarity for automated optical inspection and placement |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction enabling Zener breakdown conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective regulation where tight voltage accuracy is not required, e.g., non-critical bias networks |

Applications
| Power Rail Clamping | Reference Voltage Generation |
|---|---|
|
Use Scenario: Protecting 3.3 V microcontroller I/O pins from ESD and voltage transients in USB-peripheral interfaces. IC Role / Device Role / Timing Role: Zener diode placed between I/O line and ground to clamp excursions above 3.6 V, diverting surge current away from sensitive input structures. Use Value: Limits voltage to within absolute maximum ratings of 3.3 V logic inputs using only 0.7 mm² board area and no active components. |
Use Scenario: Providing stable bias voltage for op-amp comparators in battery-powered smoke detectors. IC Role / Device Role / Timing Role: Zener diode referenced to ground supplies fixed 3.6 V threshold to comparator input, enabling consistent smoke-alarm trigger level across battery discharge. Use Value: Achieves <±2 % threshold stability over 0–85 °C with 5 μA leakage, extending battery life by avoiding quiescent current of LDO-based references. |
| Feedback Network Regulation | Overvoltage Protection Circuit |
|
Use Scenario: Setting output voltage in adjustable buck converter feedback divider for set-top box power supplies. IC Role / Device Role / Timing Role: Zener diode replaces top resistor in resistive divider to compensate for IC reference drift, fixing regulated output at 3.6 V. Use Value: Improves output accuracy to ±1.5 % over line/load/temperature vs. ±4 % with standard resistor-only divider. |
Use Scenario: Safeguarding lithium-ion charger IC inputs against adapter overvoltage during AC/DC adapter faults. IC Role / Device Role / Timing Role: Zener diode connected between input rail and ground triggers crowbar circuit when input exceeds 3.6 V, disabling charging path. Use Value: Responds within 100 ns to overvoltage events, preventing damage to 5 V-rated charger ICs before internal protection activates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5226BS | Same 3.6 V nominal, ±5 % tolerance, but SOT-23 package (larger footprint, higher Rth(j-a) = 400 K/W) | Less suitable for high-density layouts; requires larger solder pad area and exhibits higher self-heating at 500 mW | Select when legacy SOT-23 tooling exists and thermal derating to 300 mW is acceptable |
| Vishay BZX84-C3V6 | Identical electrical specs but ±2 % tolerance option available; same SOD-123 package and 500 Ω rdif | Offers tighter voltage control for precision analog circuits where 3.6 V ±0.072 V is required vs. ±0.18 V for C-series | Choose for metrology-grade references where tighter initial tolerance justifies ~15 % cost premium |
Compared with MMBZ5226BS and BZX84-C3V6, BZT52-C3V6J provides optimal balance of thermal performance (210 K/W Rth(j-sp)), SOD123 space efficiency, and cost for mid-accuracy regulation-making it preferred for consumer power management where board area and thermal margin are constrained but automotive qualification is unnecessary.

FAQ
What is the maximum continuous reverse power this diode can handle?
The BZT52-C3V6J supports 590 mW total power dissipation at ambient temperature ≤25 °C when mounted on an FR4 PCB with single-sided copper and a 1 cm² cathode pad. Derating is required above 25 °C per the 55 K/W junction-to-solder-point thermal resistance; at 70 °C ambient, maximum continuous power drops to approximately 330 mW.
Does this part have automotive qualification?
No. Per Nexperia's Rev. 2 datasheet (October 2025), the BZT52-C3V6J is explicitly designated as non-automotive qualified. It lacks AEC-Q200 stress testing and is not recommended for safety-critical or automotive applications. Automotive alternatives are available under the -Q suffix (e.g., BZT52-C3V6J-Q) with separate qualification documentation.
How is polarity identified on the SOD123 package?
Polarity is indicated by a visible marking band on the cathode end of the SOD123 package, aligned with Pin 1 per Table 2 of the datasheet. During PCB layout, the silkscreen outline must match the cathode-marked side, and automated optical inspection systems use this band for orientation verification prior to reflow soldering.
Can this Zener be used in forward conduction mode?
Yes-the BZT52-C3V6J has a forward voltage ≤0.9 V at 10 mA, making it usable as a low-drop rectifier or ESD clamp in forward bias. However, its primary design intent is reverse-bias Zener operation; forward conduction should be limited to brief transient events, as sustained forward current above 250 mA risks permanent damage per absolute maximum ratings.
