Product details
Overview
BZT52-C2V7J from Nexperia is a ±5 % tolerance Zener diode in SOD123 package, rated for 2.7 V nominal Zener voltage at 5 mA, with 500 Ω maximum differential resistance and 20 μA reverse current at 1 V, used for low-power voltage reference and regulation in consumer power management circuits.
For engineers reviewing the BZT52-C2V7J datasheet, BZT52-C2V7J pinout, BZT52-C2V7J application, or BZT52-C2V7J equivalent, key selection criteria include Zener voltage tolerance, differential resistance, thermal resistance (210 K/W junction-to-solder-point), forward voltage (≤0.9 V @ 10 mA), and SOD123 surface-mount compatibility with standard FR4 PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load currents. Its ±5 % tolerance (C-series) and 20 μA IR at VR = 1 V support cost-sensitive regulation where precision is secondary to reliability and footprint efficiency.
Designed for ambient temperatures from −55 °C to +150 °C and junction temperatures up to 150 °C, it delivers 590 mW total power dissipation on a 1 cm² cathode pad and exhibits low thermal resistance (55 K/W to solder point), enabling use in thermally constrained PCB areas without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.7 V nominal at IZ = 5 mA; actual range 2.5–2.9 V per ±5 % tolerance - sets precise clamping level for low-voltage biasing |
| Differential Resistance (rdif) | ≤500 Ω max at IZ = 5 mA - determines output impedance and regulation sensitivity to current changes |
| Reverse Current (IR) | ≤20 μA at VR = 1 V - defines leakage-induced error in high-impedance reference nodes |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - ensures minimal conduction loss when used in series or bidirectional protection |
| Total Power Dissipation (Ptot) | 590 mW at Tamb ≤ 25 °C with 1 cm² cathode pad - defines maximum continuous DC power handling on standard PCB |
| Junction-to-Solder-Point Rth | 55 K/W - enables direct thermal coupling to copper pour for localized heat extraction in compact designs |
Pinout & Package
SOD123 plastic surface-mount package: 2-terminal, flat lead, 2.80 mm × 1.70 mm body, 0.70 mm lead width, cathode marked by band on end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking band identifies this terminal - polarity must be observed for correct Zener operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse-biased configuration enables voltage clamping at cathode |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-optimized selection for non-critical reference applications without trimming or calibration |
| Low differential resistance (≤500 Ω) | Maintains <±25 mV output shift over 1–10 mA Zener current variation - suitable for basic analog biasing |
| SOD123 footprint compatibility | Matches IPC-7351B standard land pattern (4.18 mm × 1.11 mm pad spacing) - supports automated placement and reflow |
| 150 °C maximum junction temperature | Allows operation in sealed enclosures or near heat sources without derating below 85 °C ambient |
| Non-repetitive peak reverse power (40 W) | Withstands short-duration transients (100 μs) in surge-protected input stages without degradation |
Applications
| USB Port Overvoltage Clamp | Microcontroller Reset Circuit Reference |
|---|---|
|
Use Scenario: Clamps 5 V USB supply line during hot-plug or ESD events to protect downstream LDOs and USB PHYs. IC Role / Device Role / Timing Role: Zener acts as shunt regulator, conducting excess current above 2.7 V to limit voltage excursion. Use Value: 2.7 V clamping threshold prevents damage to 3.3 V logic interfaces while allowing normal 5 V operation with margin. |
Use Scenario: Provides stable voltage reference for RC-based reset timing in 3.3 V microcontroller systems. IC Role / Device Role / Timing Role: Zener establishes fixed threshold for comparator input in manual or power-on reset generator. Use Value: ±5 % tolerance and low 20 μA leakage ensure predictable reset release time across temperature and unit variance. |
| Low-Power Sensor Bias Supply | LED Current Sink Reference |
|
Use Scenario: Supplies regulated bias voltage to analog sensor ICs (e.g., temperature or humidity sensors) in battery-powered IoT nodes. IC Role / Device Role / Timing Role: Zener serves as passive voltage reference in series with current-limiting resistor to generate stable sensor excitation. Use Value: 590 mW power rating and 210 K/W junction-to-solder-point thermal resistance allow continuous operation at 100 μA load without thermal runaway. |
Use Scenario: Sets reference voltage for constant-current LED driver circuit using single transistor and emitter resistor. IC Role / Device Role / Timing Role: Zener fixes base-emitter reference voltage, enabling predictable current through LED load independent of supply ripple. Use Value: 2.7 V nominal voltage matches common red/green LED forward drop requirements, minimizing headroom loss and improving efficiency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5222BS-7-F (Diodes Inc.) | 2.5 V nominal, ±5 %, SOD-323 package, 200 mW Ptot, 600 Ω rdif | Lower power rating and higher dynamic impedance reduce regulation accuracy under load variation | Select when board space is critical and thermal budget is limited to <200 mW |
| BZX384-C2V7 (Nexperia) | 2.7 V nominal, ±5 %, SOD-323 package, 300 mW Ptot, 500 Ω rdif, same Zener characteristics but smaller footprint | Reduced thermal mass limits sustained current handling; requires tighter layout control for thermal relief | Choose for ultra-compact designs where 300 mW dissipation suffices and SOD-323 placement is preferred |
Compared with BZT52-C2V7J, MMBZ5222BS-7-F offers smaller size but sacrifices 49 % power handling and adds 100 Ω dynamic impedance; BZX384-C2V7 matches electrical specs closely but trades 35 % lower thermal capacity for 30 % smaller footprint - both require re-evaluation of PCB copper area and transient energy absorption.

FAQ
What is the maximum continuous Zener current for BZT52-C2V7J at 70 °C ambient?
At 70 °C ambient, derated power dissipation is 413 mW (590 mW × [1 − (70−25)/125]). With 2.7 V Zener voltage, maximum continuous Zener current is 153 mA (413 mW ÷ 2.7 V). This assumes adequate PCB copper area per datasheet footnote [3] for cathode thermal pad.
Can BZT52-C2V7J be used in place of a 2.4 V Zener diode?
No - BZT52-C2V7J has a nominal 2.7 V Zener voltage (range 2.5–2.9 V); substituting for a 2.4 V part would raise clamping voltage by ≥100 mV, potentially exceeding downstream device absolute maximum ratings. Use BZT52-C2V4 (2.4 V, C-series) instead.
Is BZT52-C2V7J automotive qualified?
No - per Nexperia revision history (Table 11), C-series BZT52 parts are explicitly designated non-automotive qualified. For automotive applications, select the -Q qualified variants (e.g., BZT52-C2V7J-Q) which undergo AEC-Q101 stress testing and have extended temperature validation.
How does the 500 Ω differential resistance affect regulation accuracy under load change?
With 500 Ω rdif, a 1 mA change in Zener current causes ~0.5 mV output shift. At 5 mA nominal current, ±2 mA load variation yields ±1 mV drift - acceptable for bias references but insufficient for precision ADC references requiring <100 μV stability.
