Product details
Overview
BZT52H-B13,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD123F package, rated for 13 V nominal breakdown voltage at 5 mA, 830 mW total power dissipation, and 110 Ω maximum differential resistance - used for precision voltage reference and overvoltage protection in low-power analog supply rails.
For engineers reviewing the BZT52H-B13,115 datasheet, BZT52H-B13,115 pinout, BZT52H-B13,115 application, or BZT52H-B13,115 equivalent, this page delivers verified Zener parameters, thermal derating guidance, cathode/anode terminal mapping, and direct-fit alternatives for stable 13 V regulation in space-constrained PCB designs.
Technical Context
This Zener diode operates in reverse-biased avalanche mode to maintain a stable 13 V reference across load variations, with temperature coefficient of +0.1 mV/K at IZ = 5 mA and typical reverse current <1 μA at VR = 10.4 V. Its SOD123F footprint enables high-density placement while supporting reflow soldering only.
Thermal resistance from junction to ambient is 330 K/W (free air) and 70 K/W to solder point, enabling reliable operation up to 150 °C junction temperature when mounted on FR4 with 1 cm² cathode pad - critical for thermal stability in unregulated DC-DC feedback paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage (VZ) | 13 V at IZ = 5 mA - defines regulated output level in shunt reference circuits |
| Zener Tolerance | ±2 % - ensures voltage accuracy within ±0.26 V for tight regulation requirements |
| Differential Resistance (rdif) | 110 Ω max - determines load regulation error under current variation |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C - sets maximum continuous power before thermal derating applies |
| Forward Voltage (VF) | 0.9 V at IF = 10 mA - relevant for polarity-check circuits and ESD protection path conduction |
| Reverse Current (IR) | <1 μA at VR = 10.4 V - defines leakage-induced error in high-impedance bias networks |
| Junction Temperature Range | –65 °C to +150 °C - supports industrial and extended-temperature applications |
Pinout & Package
SOD123F surface-mount plastic package: 2-terminal, flat lead, 3.6 mm × 1.7 mm body, 0.7 mm height, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; reverse-bias anode-to-cathode voltage establishes Zener conduction |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes current path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Three tolerance grades | ±1 %, ±2 %, and ~±5 % - enables cost/performance trade-off selection per application accuracy needs |
| Wide voltage range | 2.4 V to 75 V (E24 series) - covers most analog reference and clamp requirements without redesign |
| Low thermal resistance to solder point | 70 K/W - improves power handling in thermally constrained layouts with minimal copper area |
| Reflow-solder compatible | SOD123F footprint optimized for standard Pb-free reflow profiles - eliminates hand-soldering risk |
| Non-repetitive surge rating | 80 A peak reverse current (100 μs pulse) - withstands transient overvoltage events without failure |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C13,115 | ±5 % tolerance, 130 Ω rdif, same SOD123F package | Higher voltage uncertainty (±0.65 V), looser regulation in precision references | Select when cost sensitivity outweighs regulation accuracy; suitable for non-critical clamping |
| MMSZ5243B-7-F | ±5 % tolerance, 13 V nominal, SOD-123 package, 1000 mW Ptot | Higher power rating but wider tolerance and no ±2 % grade option | Choose for higher continuous power margin where ±0.65 V tolerance is acceptable |
Compared with BZT52H-B13,115, the BZT52C13,115 trades regulation accuracy for lower unit cost, while MMSZ5243B-7-F offers greater thermal headroom but lacks tight-tolerance variants - making the H-series optimal for 13 V references demanding ±0.26 V stability.

FAQ
What is the maximum reverse current at 10.4 V for BZT52H-B13,115?
At VR = 10.4 V (80 % of nominal VZ), the reverse current is guaranteed ≤1 μA per datasheet Table 8. This low leakage ensures minimal error in high-impedance voltage divider or bias networks where current draw must be minimized.
Can BZT52H-B13,115 be used in automotive applications?
No - the BZT52H series is explicitly designated as non-automotive qualified per Revision History section 13. Automotive-grade alternatives (e.g., BZT52H-Q series) require separate qualification and are listed on Nexperia's website; use of this part in safety-critical systems is not warranted.
How does thermal resistance affect power derating above 25 °C ambient?
With Rth(j-a) = 330 K/W, power must be linearly derated above 25 °C: Pderated = 830 mW × (1 − (Tamb − 25)/125). At 85 °C ambient, maximum allowable power drops to 332 mW to maintain Tj ≤ 150 °C.
Is the SOD123F package compatible with wave soldering?
No - the datasheet explicitly states "Reflow soldering is the only recommended soldering method" (Section 12). Wave soldering risks thermal damage due to prolonged exposure; reflow profile compliance is mandatory for reliability and void-free joints.
