Product details
Overview
BZX84-C7V5,235 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, designed for precision low-power voltage reference and clamping in space-constrained PCBs. It delivers 7.5 V nominal breakdown at IZ = 5 mA, with 80 Ω max differential resistance, 15 μA max reverse current at 5.6 V, and operates across –55 °C to +150 °C ambient.
For engineers reviewing the BZX84-C7V5,235 datasheet, BZX84-C7V5,235 pinout, BZX84-C7V5,235 application, or BZX84-C7V5,235 equivalent, this part supports stable biasing in analog sensor interfaces, overvoltage protection in USB-powered peripherals, and reference generation in low-current LDO feedback networks - all requiring tight thermal stability and SMT manufacturability.
Technical Context
This Zener diode operates in reverse-biased avalanche mode, maintaining regulation via controlled breakdown at its specified VZ. Its temperature coefficient of +2.5 mV/K (at IZ = 5 mA) enables predictable drift compensation in mid-voltage references.
The device features non-repetitive peak reverse power dissipation up to 40 W (tp = 100 μs), total DC power dissipation limited to 250 mW at Tamb ≤ 25 °C on FR4 PCB, and junction-to-ambient thermal resistance of 500 K/W in free air - defining its safe operating area under transient and steady-state conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VZ | 7.0 V to 7.9 V at IZ = 5 mA - ensures ±5 % regulation window for 7.5 V nominal reference |
| Differential Resistance rdif | ≤80 Ω - maintains low output impedance for stable regulation under load variation |
| Reverse Current IR | ≤15 μA at VR = 5.6 V - minimizes standby leakage in battery-backed circuits |
| Temperature Coefficient SZ | +2.5 mV/K at IZ = 5 mA - enables predictable positive drift for thermal compensation design |
| Total Power Dissipation Ptot | 250 mW at Tamb ≤ 25 °C on standard FR4 - defines maximum continuous DC power in typical layout |
| Non-repetitive Peak Power | 40 W (tp = 100 μs) - supports transient surge suppression without failure |
| Junction Temperature Tj | –55 °C to +150 °C - enables operation in industrial and automotive-adjacent environments |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; compact 2.9 mm × 1.3 mm footprint, 1.1 mm height, and gull-wing terminations compatible with reflow and wave soldering per IPC-7351B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward-biased terminal; connects to lower-potential node in reverse-regulation configuration |
| 2 | Not Connected (n.c.) | Internal die pad with no electrical connection; must remain unconnected on PCB |
| 3 | Cathode (K) | Reverse-biased terminal; connects to higher-potential node and serves as regulated output reference point |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % voltage tolerance | Enables cost-optimized regulation where tighter accuracy is unnecessary, e.g., supply rail clamping |
| 250 mW total power rating | Supports continuous regulation in low-current applications (<10 mA) without heatsinking |
| 40 W non-repetitive surge capability | Provides robust ESD and transient immunity in I/O protection circuits without external TVS |
| 150 °C max junction temperature | Permits reliable operation in enclosed enclosures or near heat-generating components |
| SOT23 package compatibility | Enables high-density routing and automated assembly on standard SMT lines with 0.95 mm pitch |

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 MMBZ5236BS-7-F | 7.5 V ±5 %, 225 mW Ptot, 30 Ω rdif, SOT23 package | Lower rdif improves regulation accuracy but lower power derating above 25 °C | Select when tighter dynamic regulation is required and board-level thermal management is optimized |
| Vishay BZX84-C7V5-E3-08 | 7.5 V ±5 %, 300 mW Ptot, 80 Ω rdif, same SOT23 footprint | Higher Ptot allows marginally higher continuous current but identical VZ tolerance and thermal behavior | Select when extended power headroom is needed without changing layout or thermal design |
Compared with the BZX84-C7V5,235, the MMBZ5236BS-7-F offers superior regulation stiffness (30 Ω vs. 80 Ω) at the cost of reduced thermal margin, while the BZX84-C7V5-E3-08 provides 20 % higher DC power handling without altering board layout or thermal interface - making it ideal for incremental reliability upgrades.

FAQ
What is the maximum continuous forward current for BZX84-C7V5,235?
The device is not rated for continuous forward conduction; its absolute maximum forward current is 200 mA only under pulsed conditions (tp ≤ 100 μs). In normal Zener operation, it functions exclusively in reverse bias - forward voltage is specified at 0.9 V max at 10 mA, but sustained forward current degrades reliability and is outside intended use.
Can BZX84-C7V5,235 be used in place of a 7.5 V TL431 shunt regulator?
No - the BZX84-C7V5,235 is a passive two-terminal Zener diode with fixed 7.5 V breakdown, while the TL431 is an active three-terminal programmable shunt regulator offering adjustable output (2.5 V to 36 V), lower dynamic impedance (~0.2 Ω), and built-in reference/amp/comparator. Use the Zener only where simplicity, cost, and minimal footprint outweigh regulation accuracy and adjustability.
How does the "235" suffix in BZX84-C7V5,235 affect specifications?
The "235" denotes Nexperia's internal packaging and reel specification: it indicates tape-and-reel packaging per EIA-481-D standard, 3000 units per reel, and compliance with RoHS and REACH. Electrical and thermal specifications are fully defined by the base type BZX84-C7V5; the suffix adds no parametric deviation.
Is BZX84-C7V5,235 qualified for automotive applications?
No - per Nexperia's Rev. 7 datasheet (Jan 2023), the BZX84 series is explicitly designated as non-automotive qualified. It lacks AEC-Q101 stress testing and automotive-grade process controls. For automotive use, select Nexperia's BZX84-Q series variants, which include enhanced screening, extended temperature validation, and PPAP documentation.
