Product details

Overview

SMA6J10AH from Taiwan Semiconductor is a surface-mount transient voltage suppressor (TVS) diode designed for unidirectional overvoltage protection in DC power rails. It features a 10 V working stand-off voltage (V_WM), 11.1–12.3 V breakdown voltage (V_BR), 38.2 V maximum clamping voltage (V_C) at 5.0 A peak pulse current, 600 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability - deployed in on-board DC/DC converters and SMPS input stages.

For engineers reviewing the SMA6J10AH datasheet, SMA6J10AH pinout, SMA6J10AH application, or SMA6J10AH equivalent, key selection criteria include clamping performance under ISO 7637-2 Pulse 1/2a/2b/3a/3b transients, DO-214AC (SMA) package compatibility with automated SMT lines, and junction temperature range (-55°C to +175°C) for under-hood automotive environments.

Technical Context

This unidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-1.0 ps response time and low leakage (<5.0 µA at 10 V). Its single-die DO-214AC construction supports high surge robustness while maintaining low profile and J-STD-002 solderability.

The device operates within a -55°C to +175°C junction temperature range and delivers 600 W peak pulse power per 10/1000 µs waveform, with clamping voltage tightly specified at 38.2 V @ 5.0 A - enabling precise coordination with downstream IC overvoltage thresholds in 12 V automotive systems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	10 V - Maximum continuous reverse operating voltage before conduction begins; sets system rail margin for 12 V nominal bus.
V_BR @ I_T=1 mA	11.1–12.3 V - Breakdown threshold tolerance ensures consistent turn-on across production lots.
V_C @ I_PPM=5.0 A	38.2 V - Clamped voltage during 10/1000 µs surge; protects 40 V-rated MOSFETs and controllers.
P_PPM	600 W - Peak pulse power handling per standard 10/1000 µs waveform; meets ISO 7637-2 Pulse 1 & 2b requirements.
I_R @ V_WM	<5.0 µA - Low reverse leakage preserves battery drain budgets in always-on vehicle modules.
T_J Range	-55°C to +175°C - Enables placement near heat sources (e.g., power inductors) in engine control units.

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMA6J10A (ON Semiconductor)	Same DO-214AC package, identical V_WM/V_BR/V_C specs, but not AEC-Q101 qualified.	Lacks automotive qualification; suitable for industrial/commercial only.	Select when AEC-Q101 is not required and cost optimization is prioritized.
P6SMB10A (Littelfuse)	Same 10 V V_WM, but 600 W rating at 10/1000 µs, V_C = 17.0 V @ 35.3 A - lower clamping voltage but higher IPPM.	Better clamping ratio but requires higher surge current capability in system design.	Select when lower V_C is critical and board-level current paths support ≥35 A surge routing.

Compared with SMA6J10A and P6SMB10A, the SMA6J10AH provides AEC-Q101 assurance and tighter V_C specification (38.2 V @ 5.0 A), making it optimal for space-constrained automotive modules where qualification and predictable clamping behavior are mandatory.

FAQ

What is the maximum clamping voltage of SMA6J10AH at its rated peak pulse current?

The SMA6J10AH has a maximum clamping voltage (V_C) of 38.2 V when subjected to a 5.0 A peak pulse current (I_PPM) under the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and ensures compatibility with 40 V-rated downstream components in automotive and industrial power systems. The SMA6J10AH's tight V_C spec supports reliable overvoltage coordination without margin stacking.

Is SMA6J10AH suitable for automotive applications requiring AEC-Q101 qualification?

Yes, the SMA6J10AH is explicitly AEC-Q101 qualified per the manufacturer's documentation and test reports. It undergoes stress testing for temperature cycling, high-temperature operating life, and mechanical shock - confirming suitability for under-hood and body electronics. The SMA6J10AH's -55°C to +175°C operating junction range and ISO 7637-2 compliance further validate its automotive readiness.

What package type does SMA6J10AH use, and is it compatible with standard SMT assembly?

The SMA6J10AH uses the DO-214AC (SMA) surface-mount package with matte tin-plated leads that meet J-STD-002 solderability requirements. Its moisture sensitivity level is rated at Level 1 per J-STD-020, eliminating pre-bake steps. The SMA6J10AH's low-profile form factor and defined pad layout support high-yield, automated placement and reflow in high-volume manufacturing.

How does the breakdown voltage tolerance of SMA6J10AH impact circuit design?

The SMA6J10AH specifies a breakdown voltage (V_BR) range of 11.1 V to 12.3 V at 1 mA test current. This ±5.5% tolerance informs minimum headroom design between V_WM (10 V) and V_BR, ensuring reliable standoff during normal operation while guaranteeing conduction before damaging overvoltages occur. Designers must verify that this window aligns with system-level surge thresholds and downstream IC absolute maximum ratings.

Does SMA6J10AH meet international standards for automotive transient immunity?

Yes, the SMA6J10AH meets ISO 7637-2 requirements for Pulse 1 (inductive load disconnect), Pulse 2a (sudden load removal), Pulse 2b (supply interruption), Pulse 3a (capacitive coupled noise), and Pulse 3b (ground bounce). These certifications are documented in Taiwan Semiconductor's official test reports and confirm the SMA6J10AH's suitability for protecting ECUs, BCMs, and ADAS power domains against real-world vehicle network disturbances.
