Product details
Overview
BZX84-B10/DG/B3,23 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 10 V nominal breakdown voltage at 5 mA, 250 mW total power dissipation, and 40 W non-repetitive peak reverse power. It serves as a precision reference or overvoltage clamp in low-power analog supply rails and sensor biasing circuits.
For engineers reviewing the BZX84-B10/DG/B3,23 datasheet, BZX84-B10/DG/B3,23 pinout, BZX84-B10/DG/B3,23 application, or BZX84-B10/DG/B3,23 equivalent, key selection criteria include Zener voltage tolerance (±2 %), thermal resistance (330 K/W junction-to-solder point), differential resistance (≤150 Ω at IZ = 5 mA), and SOT23 footprint compatibility with automated PCB assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable DC voltage under varying load or input conditions. Its 10 V nominal Zener voltage is specified at 5 mA test current with a temperature coefficient of +4.5 mV/K, indicating positive drift with junction temperature rise.
The device features a non-connected (n.c.) terminal (Pin 2), enabling simplified layout routing while preserving mechanical stability in the SOT23 package. Its 250 mW steady-state power rating is derated above 25 °C ambient per a defined thermal resistance profile (Rth(j-a) = 500 K/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.80 V to 10.20 V at IZ = 5 mA - defines regulation window for precision 10 V reference applications |
| Tolerance | ±2 % - tighter than ±5 % C-series, suitable for mid-accuracy voltage references |
| Differential Resistance (rdif) | ≤150 Ω at IZ = 5 mA - determines output impedance and load regulation error |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for tp = 100 μs - supports transient surge suppression in low-energy protection circuits |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables operation in industrial ambient environments without active cooling |
| Reverse Current (IR) | ≤20 μA at VR = 7.6 V - ensures low leakage before breakdown onset |
Pinout & Package
Package: SOT23 (TO-236AB), surface-mount plastic package with 3 leads, 1.9 mm × 1.1 mm body size, 0.45 mm lead pitch, and standard reflow-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connected to lower-potential side of regulated node; forward-biased during normal conduction |
| 2 | Not Connected (n.c.) | Electrically isolated terminal; no internal bond wire; used for mechanical anchoring only |
| 3 | Cathode (K) | Connected to higher-potential side; reverse-biased during Zener regulation; primary heat path to PCB |
Key Features
| Feature | Design Value |
|---|---|
| Stable 10 V reference | Guaranteed 9.80–10.20 V range at 5 mA enables accurate biasing of op-amps and ADC references |
| Low thermal resistance | Rth(j-sp) = 330 K/W to cathode solder point improves power handling in compact layouts |
| High surge capability | 40 W peak reverse power withstand for 100 μs pulses supports ESD and transient clamping |
| SOT23 footprint compatibility | Standardized 3-lead SMT outline allows drop-in replacement across BZX84 series variants |
| Wide operating temperature | −55 °C to +150 °C junction range supports deployment in automotive under-hood and industrial control modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5240B | 10 V nominal, ±5 % tolerance, 350 mW Ptot, SOT23 package | Looser tolerance and higher power rating suit cost-sensitive, non-critical regulation | Select when ±5 % accuracy suffices and higher continuous power margin is required |
| Vishay BZX84-C10 | 10 V nominal, ±5 % tolerance, same SOT23 package and 250 mW rating | Higher IR (≤50 μA at VR = 7.6 V) and wider VZ spread reduce reference stability | Choose only for legacy design continuity where ±5 % tolerance is acceptable |
Compared with MMBZ5240B and BZX84-C10, the BZX84-B10/DG/B3,23 offers tighter ±2 % voltage tolerance and lower differential resistance (150 Ω vs. ~200 Ω), making it preferable for applications demanding improved regulation accuracy and reduced load-induced voltage shift.

FAQ
What is the Zener test current for BZX84-B10/DG/B3,23?
The nominal Zener voltage of 9.80–10.20 V is specified at a test current of 5 mA, as defined in Table 8 of the Nexperia datasheet Rev. 7. This current establishes the operating point for regulation accuracy, differential resistance, and temperature coefficient measurements.
Can BZX84-B10/DG/B3,23 be used in place of BZX84-A10?
No - BZX84-A10 has ±1 % tolerance (9.90–10.10 V), while BZX84-B10/DG/B3,23 has ±2 % (9.80–10.20 V). Substituting introduces up to 0.2 V additional uncertainty, which may violate accuracy requirements in precision reference designs.
What is the maximum allowable ambient temperature at full 250 mW dissipation?
Full 250 mW power dissipation is only rated at Tamb ≤ 25 °C. Above this, derating applies: at 75 °C ambient, maximum dissipation drops to approximately 125 mW, based on Rth(j-a) = 500 K/W and Tj(max) = 150 °C.
Is Pin 2 internally connected?
No - Pin 2 is explicitly marked "n.c." (not connected) in Table 2 of the datasheet. It is electrically isolated with no internal bond wire, serving solely as a mechanical anchor for the SOT23 package during PCB mounting and reflow.
