Product details
Overview
SMB10J16CAH from Taiwan Semiconductor is a bidirectional 1000W transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, with 16V standoff voltage (VWM), 17.8–19.7V breakdown voltage (VBR @ 1mA), and 26.0V clamping voltage (VC @ 38.5A). It delivers AEC-Q101 qualification and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive load-dump and inductive switching protection.
For engineers reviewing the SMB10J16CAH datasheet, SMB10J16CAH pinout, SMB10J16CAH application, or SMB10J16CAH equivalent, key selection criteria include bidirectional clamping capability, 1000W peak pulse power rating at 1ms, junction temperature range of –55°C to +175°C, and compliance with automotive ESD and electrical fast transient immunity standards.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-1ps response time and stable clamping under repetitive transients. Its symmetrical I-V characteristic enables protection against both positive and negative polarity surges without external polarity management.
Designed for surface-mount placement in space-constrained automotive ECUs and lighting modules, it features matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance, with UL 94V-0 molding compound and MSL Level 1 moisture sensitivity.

Applications
| Automotive Body Control Module (BCM) | LED Headlamp Driver Protection |
|---|---|
Use Scenario: Protects microcontroller I/O and CAN transceiver lines from load-dump spikes during battery disconnect/reconnect events. IC Role / Device Role / Timing Role: Bidirectional clamping device placed at board-level input filter stage, shunting surge energy to ground before reaching sensitive logic. Use Value: Limits transient voltage to ≤26.0 V during 1000W pulses, preventing latch-up or gate oxide damage in 3.3V/5V automotive MCUs. | Use Scenario: Shields constant-current LED driver ICs from inductive kickback generated by relay or MOSFET switching in headlamp dimming circuits. IC Role / Device Role / Timing Role: Parallel-connected TVS across driver output, activated within <1 ps to clamp flyback voltage before driver overvoltage shutdown triggers. Use Value: Enables use of lower-voltage-rated driver ICs (e.g., 30V max) while surviving 40V+ inductive spikes common in 12V automotive systems. |
| Industrial PLC Digital Input Module | Automotive Infotainment Power Rail Protection |
Use Scenario: Guards 24V DC digital input channels against EFT bursts and cable discharge events in factory automation equipment. IC Role / Device Role / Timing Role: Primary front-end surge suppression element on field-side connector, coordinated with series impedance and filtering capacitors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | Same DO-214AA package, 1000W PPK, but VBR = 17.8–19.7V and VC = 26.0V - identical electrical specs; differs only in manufacturer (Bourns) and RoHS/halogen-free compliance documentation | Approved for same AEC-Q101 and ISO 7637-2 use cases; Bourns variant has alternate date coding and tape/reel packaging configuration | Select SMBJ16CA when dual-sourcing is required or when Bourns' supply chain alignment better matches production schedule |
| P6SMB16CA | Same footprint and ratings, but VBR = 17.8–19.7V and VC = 26.0V; manufactured by Vishay; slightly higher RθJA (110°C/W vs. 100°C/W) and different MSL level (Level 1 confirmed) | Validated in identical automotive lighting and BCM applications; minor thermal derating difference requires verification at >85°C ambient | Choose P6SMB16CA where Vishay's long-term product longevity assurance or regional distribution coverage is prioritized |
Compared with SMBJ16CA and P6SMB16CA, SMB10J16CAH offers identical clamping performance and automotive qualification, but with Taiwan Semiconductor's optimized thermal resistance (RθJA = 100°C/W) and documented halogen-free compliance per IEC 61249-2-21 - advantageous for thermally constrained PCB layouts and strict environmental compliance programs.

FAQ
What is the polarity configuration of SMB10J16CAH?
SMB10J16CAH is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative transients without requiring orientation during PCB placement. Unlike unidirectional variants (e.g., SMB10J16AH), it has no cathode band marking and functions identically regardless of terminal connection - critical for protecting differential or AC-coupled signal paths in automotive networks.
Does SMB10J16CAH meet AEC-Q101 stress test requirements?
Yes, SMB10J16CAH is fully AEC-Q101 qualified, having passed temperature cycling, highly accelerated life testing (HALT), and ESD testing per the AEC-Q101-004 standard. This qualification confirms its suitability for under-hood automotive applications where reliability under thermal shock, humidity, and voltage stress is mandatory - a requirement explicitly stated in the official TSC datasheet Version A2102.
What is the maximum clamping voltage of SMB10J16CAH under surge conditions?
The maximum clamping voltage of SMB10J16CAH is 26.0 V at a peak pulse current (IPPM) of 38.5 A, measured using the standardized 10/1000 μs double-exponential waveform. This value is guaranteed across the full operating temperature range and ensures downstream components see no more than 26.0 V during worst-case transients - a key parameter verified in the Electrical Specifications table of the SMB10J16CAH datasheet.
Can SMB10J16CAH be used in place of SMB10J16AH in a design?
No - SMB10J16CAH is bidirectional while SMB10J16AH is unidirectional. Substituting them without circuit review risks failure: SMB10J16AH conducts forward current during negative transients, potentially damaging upstream drivers. SMB10J16CAH must be used only where symmetrical clamping is required; if polarity is controlled elsewhere in the system, SMB10J16AH may offer lower leakage but requires correct orientation.
What is the thermal resistance from junction to ambient for SMB10J16CAH?
The junction-to-ambient thermal resistance (RθJA) of SMB10J16CAH is 100 °C/W, measured under standard JEDEC test conditions (single device on 1-inch² FR-4 board with 2 oz copper). This value defines the allowable power derating above 25°C ambient - for example, at 85°C ambient, maximum usable peak power drops to ~600W per the Pulse Derating Curve in the SMB10J16CAH datasheet Figure 2.
