Product details
Overview
SMA6J15AHR3G from Taiwan Semiconductor is a 600W surface-mount transient voltage suppressor (TVS) diode with a 15V working standoff voltage (VWM), 16.7–18.5V breakdown voltage (VBR), and 23.6V clamping voltage (VC) at 25.4A peak pulse current, designed for automotive and industrial power line surge protection in DC/DC converters and SMPS.
For engineers reviewing the SMA6J15AHR3G datasheet, SMA6J15AHR3G pinout, SMA6J15AHR3G application, or SMA6J15AHR3G equivalent, key selection criteria include its DO-214AC (SMA) package, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, 175°C junction temperature rating, and 1.0ps typical response time-critical for robust ESD and load-dump immunity in embedded power systems.
Technical Context
This unidirectional TVS diode operates as a reverse-biased avalanche clamp, activated when transient voltage exceeds VBR (16.7–18.5V @ 1mA). Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0µA @ 15V).
The device handles 600W peak pulse power per 10/1000µs waveform, with clamping voltage fixed at 23.6V under 25.4A impulse, enabling predictable overvoltage limiting without system shutdown during ISO-compliant transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 16.7 / 18.5 V @ 1 mA - Confirmed avalanche onset range for reliable turn-on threshold |
| VC @ IPPM | 23.6 V @ 25.4 A - Clamped voltage during full 600W transient, defining worst-case rail overshoot |
| PPPM | 600 W (10/1000µs) - Peak surge energy absorption capacity per IEC/ISO standard waveform |
| TJ max | 175 °C - Maximum junction temperature enabling operation in under-hood or high-ambient industrial environments |
| IR @ VWM | <1.0 µA - Negligible leakage current preserving efficiency in always-on power rails |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, single-diode configuration with cathode band polarity marking. Weight: 0.060 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional clamp configuration |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12V rail); avalanche conduction occurs when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity stress |
| ISO 7637-2 compliance | Validated for automotive load-dump (Pulse 2b), supply interruption (Pulse 3b), and coupled transients (Pulse 1/2a/3a) |

| Moisture sensitivity level 1 | Enables standard SMT reflow without baking, reducing manufacturing overhead |
Applications
| Automotive Body Control Module (BCM) | Industrial DC/DC Converter Input Stage |
|---|---|
Use Scenario: Protecting 12V supply lines in BCMs against battery load-dump pulses up to 35V and ISO 7637-2 Pulse 2b. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between input rail and ground, conducting only during overvoltage events. Use Value: Limits rail voltage to ≤23.6V during 600W transients, preventing damage to MCU power supplies and CAN transceivers. | Use Scenario: Safeguarding isolated DC/DC converter primary-side inputs from switching noise and external surges in factory automation equipment. IC Role / Device Role / Timing Role: Standoff protector on input bus; remains non-conductive below 15V, activates within 1ps when transients exceed VBR. Use Value: Maintains system uptime by absorbing 10/1000µs surges without latch-up or degradation, supporting >100,000 surge cycles. |
| LED Driver Power Supply | USB-C PD Adapter Secondary Side |
Use Scenario: Suppressing inductive kickback and lightning-induced surges on constant-current LED string drivers used in street lighting. IC Role / Device Role / Timing Role: Reverse-biased TVS across output terminals, clamping flyback spikes generated by MOSFET switching. Use Value: Prevents LED driver IC failure by capping transient voltage at 23.6V while sustaining 175°C operation in enclosed luminaires. | Use Scenario: Protecting secondary-side 20V output rails in USB-C PD adapters against coupling from primary-side transients and ESD events. IC Role / Device Role / Timing Role: Clamp placed between VOUT and GND, rated for 15V nominal but tolerating 23.6V clamping during 25.4A impulses. Use Value: Enables compliance with IEC 61000-4-2 Level 4 (15kV air/8kV contact) without additional filtering components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J15AHE3/73 (Vishay) | Same DO-214AC package, identical VWM/VBR/VC specs, RoHS/halogen-free compliant | Qualified to AEC-Q101; preferred for automotive production where qualification traceability is required | Select SMA6J15AHE3/73 when AEC-Q101 certification is mandatory; otherwise SMA6J15AHR3G offers equivalent electrical performance |
| P6SMB15A (ON Semiconductor) | Same 15V VWM, but higher VC = 24.4V @ 24.5A; 600W rating, DO-214AA (SMB) package (larger footprint) | Higher clamping voltage increases risk of downstream overstress; SMB package requires PCB layout change | Choose P6SMB15A only if existing design uses SMB footprint and 0.8V higher clamping is acceptable |
Compared with SMA6J15AHE3/73, SMA6J15AHR3G provides identical clamping behavior and surge rating but lacks AEC-Q101 documentation; versus P6SMB15A, it delivers tighter VC control and smaller DO-214AC footprint-critical for space-constrained DC/DC modules.

FAQ
What is the maximum clamping voltage of SMA6J15AHR3G under peak pulse conditions?
The SMA6J15AHR3G has a maximum clamping voltage (VC) of 23.6 V when subjected to its rated peak pulse current of 25.4 A, measured using the standardized 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuits during surge events and is confirmed in the official Taiwan Semiconductor datasheet revision E2102. The SMA6J15AHR3G maintains this clamping performance across its specified operating temperature range.
Is SMA6J15AHR3G compliant with automotive transient standards?
Yes, SMA6J15AHR3G meets ISO 7637-2 requirements for Pulses 1, 2a, 2b, 3a, and 3b, making it suitable for automotive power line protection including load-dump and supply interruption transients. It is not AEC-Q101 qualified out-of-the-box, but its electrical and thermal specifications-including 175°C TJ max and glass-passivated junction-support automotive under-hood deployment when validated per customer requirements. The SMA6J15AHR3G datasheet explicitly cites ISO 7637-2 compliance.
What is the package type and mounting configuration of SMA6J15AHR3G?
SMA6J15AHR3G uses the DO-214AC (SMA) surface-mount package, featuring a single-diode configuration with cathode indicated by a band. It is supplied in tape-and-reel format (7,500 units per reel) and is compatible with standard reflow soldering processes. The SMA6J15AHR3G package meets UL 94V-0 flammability rating and JESD201 Class 2 whisker resistance, supporting automated placement and high-reliability assembly.
How does SMA6J15AHR3G compare to SMA6J15A in terms of specifications and marking?
SMA6J15AHR3G is the tape-and-reel variant of the SMA6J15A base part, with identical electrical and thermal specifications-including VWM = 15 V, VBR = 16.7–18.5 V, VC = 23.6 V, and 600 W peak power. The "HR3G" suffix denotes packaging (high-reliability tape-and-reel, 7,500/reel, green compound), while the marking code is "6BM". No parametric difference exists between SMA6J15A and SMA6J15AHR3G-the SMA6J15AHR3G designation reflects fulfillment format, not functional variation.
What is the steady-state power dissipation rating for SMA6J15AHR3G?
The SMA6J15AHR3G has a steady-state power dissipation (PD) rating of 4 W at TA = 25°C, as specified in the Absolute Maximum Ratings table. This value applies to continuous DC or low-frequency reverse-bias conditions-not transient events. For sustained power handling, thermal design must ensure junction temperature remains ≤175°C; derating is required above 25°C ambient, per the published pulse derating curve in the SMA6J15AHR3G datasheet.
