Product details
Overview
1SMA130ZH from Taiwan Semiconductor is a surface-mount Zener diode rated for 130 V nominal zener voltage at 1.9 mA test current, 1 W power dissipation, and 700 Ω dynamic impedance at IZT, designed for precision voltage regulation and overvoltage protection in automotive and industrial power rails.
For engineers reviewing the 1SMA130ZH datasheet, 1SMA130ZH pinout, 1SMA130ZH application, or 1SMA130ZH equivalent, key selection criteria include its AEC-Q101 qualification, DO-214AC (SMA) package with cathode band polarity marking, low leakage (<0.25 µA at 98.8 V), and non-repetitive surge capability up to 5000 mA.
Technical Context
This device operates as a single-die, glass-passivated Zener diode with a tightly controlled ±5% tolerance on nominal zener voltage and a junction temperature range of –55°C to +175°C. Its low-inductance SMA package supports high-frequency transient suppression and automated placement.
The 1SMA130ZH exhibits a typical leakage current of ≤0.25 µA at 98.8 V (80% of VZ), with zener impedance measured at 700 Ω under 1.9 mA DC bias plus 0.19 mA RMS AC signal at 1 kHz - confirming stable regulation in low-current reference circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ @ IZT | 130 V ±5% at 1.9 mA - defines precise clamping threshold for 120–140 V system protection |
| PD | 1 W continuous - supports steady-state regulation without heatsinking on standard PCB copper |
| ZZT @ IZT | 700 Ω - ensures minimal voltage deviation under load changes in feedback or reference paths |
| IR @ VR | <0.25 µA at 98.8 V - enables ultra-low quiescent current in battery-backed or energy-harvesting circuits |
| TJ max | +175°C - allows operation in under-hood automotive or high-ambient industrial environments |
| Surge ISM | 5000 mA (non-repetitive, 1/120 s) - withstands lightning-induced transients per ISO 7637-2 Pulse 1/2 |
| Package | DO-214AC (SMA) - industry-standard SMT footprint compatible with JEDEC MS-013, 5 mm × 3.5 mm body |
Pinout & Package
DO-214AC (SMA) package: molded epoxy case with matte tin-plated leads, cathode indicated by a visible band; polarity-critical for reverse-bias operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / low-impedance path during surge | Connected to ground or lower-potential rail; carries forward surge current up to 30 A (IFSM) |
| Cathode | Zener breakdown terminal / regulated output node | Connected to protected node; maintains stable 130 V clamp when reverse biased above VZ |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD47 |
| Glass passivated junction | Eliminates moisture ingress risk and improves long-term VZ stability vs. silicon nitride alternatives |
| Low inductance SMA package | Reduces ringing during fast transients - critical for EMC-compliant CAN/LIN bus protection |
| Moisture sensitivity level 1 | Enables direct placement without baking; supports lead-free reflow per J-STD-020 |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU Directive 2011/65/EU for green manufacturing |
Applications
| Automotive Power Rail Protection | Industrial Sensor Reference Supply |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5372B | Same 130 V nominal VZ, but 5 W rating in DO-201AD package; higher thermal mass, larger footprint | Suitable for higher-power derating scenarios where board space permits larger package | Select 1N5372B only if >1 W continuous dissipation is required and DO-201AD layout is available |
| BZX84-C130 | 130 V ±5%, but 300 mW rating in SOT-23; significantly lower surge capability (1000 mA max) | Limited to low-energy signal-level clamping, not suitable for power rail protection | Choose BZX84-C130 only for space-constrained signal conditioning, not for 1SMA130ZH's 1 W/5000 mA use cases |
Compared with 1N5372B and BZX84-C130, the 1SMA130ZH uniquely balances 1 W continuous power, 5000 mA surge robustness, and compact DO-214AC packaging - making it optimal for automotive and industrial SMT designs requiring both precision and ruggedness.

FAQ
What is the exact zener voltage tolerance and test condition for 1SMA130ZH?
The 1SMA130ZH has a nominal zener voltage of 130 V with a standard tolerance of ±5%, measured at 1.9 mA test current (IZT) while maintaining lead temperature at 30°C ±1°C per JEDEC registration. This ensures consistent clamping behavior across production lots and operating conditions.
Is 1SMA130ZH suitable for automotive applications?
Yes, the 1SMA130ZH is AEC-Q101 qualified and rated for junction temperatures from –55°C to +175°C. Its glass-passivated junction, low leakage (<0.25 µA), and 5000 mA non-repetitive surge capability make it appropriate for under-hood and powertrain-related voltage regulation and protection in automotive ECUs and ADAS modules.
What is the maximum non-repetitive surge current rating for 1SMA130ZH?
The 1SMA130ZH is rated for a non-repetitive peak reverse surge current of 5000 mA, defined as a 1/120 second duration half-sine wave pulse per JEDEC standards. This rating applies at ambient temperature and supports compliance with ISO 7637-2 transient immunity requirements.
Does 1SMA130ZH have a halogen-free and RoHS-compliant construction?
Yes, the 1SMA130ZH meets RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The molding compound is UL 94V-0 rated, and terminals are matte tin plated - ensuring environmental compliance and solderability in lead-free reflow processes.
What package type and polarity marking does 1SMA130ZH use?
The 1SMA130ZH uses the DO-214AC (SMA) surface-mount package with a visible cathode band marking the cathode terminal. The anode connects to the unmarked end, and polarity must be observed for correct reverse-bias operation in regulation or protection circuits.
