Product details
Overview
SMBJ130AH from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, rated for 600W peak pulse power, 130V working stand-off voltage (VWM), and 209V maximum clamping voltage (VC) at 3.0A peak impulse current. It provides robust ESD and electrical fast transient protection for automotive and industrial power rails.
For engineers reviewing the SMBJ130AH datasheet, SMBJ130AH pinout, SMBJ130AH application, or SMBJ130AH equivalent, key selection criteria include its AEC-Q101 qualification, 1μA leakage at 130V, 150°C junction temperature rating, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, and unidirectional polarity with cathode band marking.
Technical Context
The SMBJ130AH operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 144–159V breakdown range (VBR @ 1mA). Its glass-passivated junction ensures stable clamping performance under repetitive transients, while the DO-214AA package supports automated placement and meets JESD201 Class 2 whisker resistance.
Thermal design is enabled by RθJC = 10°C/W and RθJA = 55°C/W ratings, allowing reliable operation up to 150°C junction temperature. It delivers sub-1ps response time and maintains <1μA blocking leakage above 130V, meeting stringent automotive immunity requirements per ISO 7637-2.

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12V/24V supply lines in engine control units (ECUs), body control modules (BCMs), and infotainment systems from load dump and inductive switching spikes. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between power rail and ground, absorbing energy from ISO 7637-2 Pulse 1 (−120V/−150V) and Pulse 2a (−100V). Use Value: Limits rail voltage to ≤209V during 3.0A surge, preventing damage to downstream DC-DC converters and microcontrollers rated for 36V absolute max. | Use Scenario: Safeguarding analog sensor inputs (e.g., pressure, temperature, position sensors) in PLCs and motor drives against ESD and fast transients. IC Role / Device Role / Timing Role: Low-leakage (≤1µA) TVS placed at connector interface, shunting ESD events before they reach precision amplifier front-ends. Use Value: Maintains signal integrity with <1µA leakage at 130V, avoiding DC offset errors in µA-level sensor bias networks while clamping ±15kV contact ESD per IEC 61000-4-2. |
| LED Lighting Driver Protection | Telecom Power Supply Input Protection |
Use Scenario: Shielding constant-current LED drivers in automotive headlamps and street lighting from voltage surges caused by relay switching or lightning-induced coupling. IC Role / Device Role / Timing Role: Unidirectional TVS connected across input terminals of buck/boost driver ICs, triggered only during overvoltage events. Use Value: Withstands 600W peak pulses and clamps to 209V, ensuring driver ICs (e.g., TPS92692, LM3409) remain within their 65V absolute maximum rating. | Use Scenario: Front-end protection for 48V telecom power supplies subjected to repetitive surges per ITU-T K.20/K.21 standards. IC Role / Device Role / Timing Role: Primary surge suppression device on DC input bus, coordinated with upstream fuses and downstream MOVs. Use Value: Provides precise 130V standoff and 209V clamping-tighter tolerance than generic MOVs-enabling accurate coordination with secondary overvoltage protection circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | Same VWM (130V), but VBR min/max = 144–176V vs. 144–159V; higher VC = 231V @ 2.7A | Less precise clamping; higher let-through voltage may stress downstream 200V-rated components | Select SMBJ130AH when tighter VBR distribution and lower VC are required for margin-critical designs |
| SMAJ130AHE3/57T | VWM = 130V, but SMA package (DO-214AC); PPK = 400W; VC = 219V @ 2.3A | Lower power rating and larger clamping voltage reduce protection margin in high-energy surge environments | Choose SMBJ130AH for 600W capability and DO-214AA footprint compatibility in space-constrained automotive PCBs |
Compared with SMBJ130A and SMAJ130AHE3/57T, SMBJ130AH offers superior clamping precision (209V vs. 231V/219V) and full 600W surge capacity in the industry-standard SMB outline-critical for AEC-Q101-compliant automotive power rail protection where voltage margin and thermal robustness are non-negotiable.

FAQ
What is the breakdown voltage range for SMBJ130AH?
The SMBJ130AH has a guaranteed breakdown voltage (VBR) range of 144 V to 159 V at 1 mA test current, measured per ANSI/IEEE C62.35. This narrow distribution ensures consistent clamping behavior across production lots and supports precise overvoltage protection design margins in safety-critical automotive applications.
Is SMBJ130AH suitable for bidirectional transient protection?
No, SMBJ130AH is a unidirectional TVS diode intended for DC rail protection with defined polarity. For bidirectional applications, Taiwan Semiconductor specifies parts with "CH" or "CAH" suffixes (e.g., SMBJ130CH). Using SMBJ130AH in AC or bipolar configurations risks failure due to forward conduction during negative half-cycles.
What is the maximum clamping voltage of SMBJ130AH and at what current is it specified?
The SMBJ130AH has a maximum clamping voltage (VC) of 209 V, specified at a peak impulse current (IPP) of 3.0 A using the standardized 10/1000 µs double-exponential waveform. This value defines the highest voltage seen by protected circuitry during a surge event and is validated per IEC 61000-4-5 test conditions.
Does SMBJ130AH require moisture baking before reflow soldering?
No, SMBJ130AH has a moisture sensitivity level (MSL) of 1 per J-STD-020, meaning it is not moisture-sensitive and can be used directly in standard SMT reflow processes without pre-bake. This eliminates handling complexity and reduces risk of delamination or popcorning during assembly.
How does SMBJ130AH meet automotive electromagnetic compatibility requirements?
SMBJ130AH meets ISO 7637-2 Pulse 1 (load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (line impedance coupling) requirements, and is AEC-Q101 qualified for temperature cycling, high-temperature reverse bias, and ESD. These certifications validate its suitability for automotive power rail protection in harsh EMI environments.
