Product details
Overview
SMB10J36AH from Taiwan Semiconductor is a unidirectional 1000W transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, with 36V standoff voltage (VWM), 40.0–44.2V breakdown voltage (VBR @ 1mA), and 58.1V clamping voltage (VC @ 17.2A). It delivers AEC-Q101 qualification, <1.0ps response time, and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive load-dump and inductive switching protection.
For engineers reviewing the SMB10J36AH datasheet, SMB10J36AH pinout, SMB10J36AH application, or SMB10J36AH equivalent, key selection criteria include unidirectional polarity, 1000W peak pulse power rating at 1ms, junction temperature range of –55°C to +175°C, and compliance with JESD201 Class 2 whisker resistance and J-STD-020 moisture sensitivity level 1.
Technical Context
This TVS diode operates as a shunt-clamping overvoltage protector, triggered when reverse voltage exceeds VBR (40.0–44.2V), diverting transient current away from downstream circuitry. Its glass-passivated junction ensures stable leakage performance (<1µA @ 36V) and robust surge handling under repetitive or single-pulse stress.
Designed for automotive-grade reliability, SMB10J36AH supports bidirectional variants via CAH suffix (e.g., SMB10J36CAH), but the AH version is strictly unidirectional with cathode band marking. Thermal performance includes RθJL = 20°C/W and RθJA = 100°C/W, enabling operation up to 175°C junction temperature without derating in PCB-constrained layouts.
Key Specifications

Applications
| Automotive Power Rail Protection | LED Lighting Driver Protection |
|---|---|
Use Scenario: 12V battery-fed ECUs exposed to load-dump pulses up to 35V and inductive kickback during relay switching. IC Role / Device Role / Timing Role: Shunt-clamping TVS placed between power rail and ground, activated within <1ps to clamp transients below IC absolute maximum ratings. Use Value: Limits peak rail voltage to ≤58.1V during 1000W transients, preventing latch-up or gate oxide rupture in MCU and CAN transceivers. | Use Scenario: Constant-current LED drivers in headlamps subjected to ESD events and fast-switching noise from adjacent DC-DC converters. IC Role / Device Role / Timing Role: Unidirectional TVS on driver output node, absorbing ±8kV contact ESD (IEC 61000-4-2) and electrical fast transients. Use Value: Maintains <1µA leakage at 36V standby, avoiding false triggering while clamping ESD pulses to safe levels for GaN/BJT driver stages. |
| Industrial Sensor Interface Protection | Automotive Body Control Module (BCM) |
Use Scenario: Analog sensor inputs (e.g., pressure, temp) connected to long harnesses in factory automation systems vulnerable to induced surges. IC Role / Device Role / Timing Role: Low-capacitance TVS on signal line, placed immediately before ADC input or op-amp buffer. Use Value: Provides 58.1V clamping without adding signal distortion-no impact on 12-bit ADC accuracy due to sub-1pF parasitic capacitance. | Use Scenario: BCM power distribution network managing window lifters, door locks, and mirror controls with multiple inductive loads. IC Role / Device Role / Timing Role: Primary rail-level TVS on fused 12V feed, coordinated with secondary TVS on individual load outputs. Use Value: Withstands repeated 100A surge currents (IFSM) and maintains clamping stability across –40°C to +125°C ambient, ensuring functional safety integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ36A | Same DO-214AC (SMA) package; 36V VWM, 58.1V VC @ 17.2A, but lower PPK (400W) and no AEC-Q101 qualification | Not rated for automotive under-hood use; limited to industrial/commercial environments | Select SMAJ36A only if AEC-Q101 and 1000W pulse rating are not required |
| ON Semiconductor 1.5SMC36A | DO-214AB (SMC) package; 36V VWM, 58.1V VC @ 17.2A, 1500W PPK, AEC-Q101 qualified, but larger footprint and higher RθJA (70°C/W) | Better power handling but requires more PCB area and thermal relief; less suitable for space-constrained modules | Choose 1.5SMC36A when higher surge margin is needed and board space allows SMC footprint |
Compared with SMAJ36A and 1.5SMC36A, SMB10J36AH uniquely balances AEC-Q101 compliance, 1000W pulse capability, and compact DO-214AA footprint-making it optimal for automotive body electronics where space, qualification, and transient immunity must coexist.

FAQ
What is the polarity configuration of SMB10J36AH?
SMB10J36AH is a unidirectional TVS diode, configured with anode and cathode terminals. The cathode is marked by a band on the DO-214AA package body. It conducts only during reverse-biased overvoltage events and blocks forward current up to 3.5V at 50A, making it suitable for DC power rail protection where polarity is fixed.
Does SMB10J36AH meet automotive qualification standards?
Yes, SMB10J36AH is AEC-Q101 qualified and tested per the full stress test schedule including high-temperature operating life, temperature cycling, unbiased highly accelerated stress test, and ESD. It also meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements-confirming its suitability for automotive power networks.
What is the maximum clamping voltage for SMB10J36AH under transient conditions?
The maximum clamping voltage (VC) for SMB10J36AH is 58.1 V at a peak pulse current (IPPM) of 17.2 A, measured using the 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and ensures protected ICs remain below their absolute maximum voltage ratings during standardized surge events.
Can SMB10J36AH be used in bidirectional applications?
No-SMB10J36AH is unidirectional only. For bidirectional transient suppression, Taiwan Semiconductor offers the SMB10J36CAH variant, which uses a center-tapped dual-diode configuration. Using SMB10J36AH in AC or reversible-polarity circuits may result in forward conduction failure or permanent damage.
What packaging and reel quantity is available for SMB10J36AH?
SMB10J36AH is supplied in DO-214AA (SMB) package on tape-and-reel format, with 3,000 units per reel. The tape meets EIA-481 standards, and the reels are compatible with standard high-speed pick-and-place equipment, supporting automated SMT assembly without modification.
